Physics Education Research involving demonstrations and simulationsPREFACE TO THE EXPANDED VERSIONBefore composing the Resource Letter, PhD-2: Physics Demonstrations, I prepared this much larger list, with considerably more detailed annotations. This original list was then reduced down to accommodate the size restrictions of the American Journal of Physics, but the notes were helpful in determining details of the reduction. Because it contains a large amount of material that could not be put in the AJP, I have decided to put this expanded version on the web, so that more interested people could have the benefit of the additional references as well as my more detailed thoughts regarding these materials. I have also included the Table of Contents for convenience in finding information in this larger format.I have personally reviewed all of the books and web sites in this list. The books selected were (1) those found in my personal library, about 50 titles collected over my approximately 40 year career at the University of Maryland, (2) a large collection that will be found in the University of Maryland Physics Lecture-Demonstration Facility, and (3) all of the books on demonstrations that I could find in the American Association of Physics Teachers store and libraries at the American Center for Physics in their College Park, Maryland, building. In addition, I have included several books that were called to my attention during the AJP review process. I have perused the web sites and used computer programs from the sites that are reviewed, and have given special attention to several of those that I found helpful in my teaching as well as in the Physics is Phun public demonstration programs.This Resource Letter provides a guide to physics demonstrations, computer simulations of physics demonstrations, and physics education research regarding use and effectiveness of demonstrations and simulations. Articles, books, and materials on the internet are cited for the following: professional journals dealing with demonstrations, web sites of professional organizations, workshops including use of demonstrations and simulations, books dealing with demonstrations in classroom teaching as well as informal settings, web sites for physics demonstrations, videos of physics demonstrations, demonstration simulations, and physics education research regarding use of demonstrations in teaching.INTRODUCTIONUse of physics demonstrations is important in several major areas: (1) physics classes in college/university and pre-college, (2) demonstration shows and/or programs, (3) hands-on and museum settings, (4) hallway or corridor demonstrations, and (5) home or other informal use. Although there is a substantial overlap in the equipment and materials for these activities, there are significant differences in both the sophistication of the apparatus and the approach toward the demonstrations. This document will attempt to provide some information regarding all of these areas, with emphasis on use of demonstrations in lectures. During the past fifteen years, web sites have come on line with virtually all the information necessary to construct and teach using almost any demonstration. More recently, using high-quality digital video cameras and computer-based editors, many sites have created large collections of videos showing their demonstrations in use. Another recent development is the availability on the web of a large variety of computer simulations of demonstrations. Physics education research is currently studying these teaching materials and provides us with well documented data on how they may be effectively used. Important related information can be obtained from many University web sites, including sources of equipment and materials, lists of demonstrations used in various classes, and suggested demonstrations for elementary physics classes to guide the less experienced teacher. JournalsA number of Journals include information regarding physics lecture demonstrations and their use, and several have included (at various times in their history) columns dealing with demonstrations. The American Journal of Physics (AJP) regularly discusses demonstrations, often at a relatively advanced level, while The Physics Teacher (TPT) is aimed at both high school and college education. The Physics Teacher includes papers on demonstrations in every issue, usually at a lower technical level than the AJP. Over the years several columns in these periodicals have been featured dealing largely with demonstrations, sometimes appearing regularly and sometimes appearing irregularly. Many of these columns have been incorporated into book form and published by the AAPT; see the list of demonstration books for additional information. The indexes for papers in the AJP and TPT, found yearly in the December issues, are organized using the Physics and Astronomy Classification Scheme (PACS). The primary topics of interest here are:01.50.M Demonstration experiments and apparatus01.50.P Laboratory experiments and apparatus01.40.F Research in physics education02.70 Computational techniques; simulationsThe primary journals in which relevant literature will be found are those published by the American Association of Physics Teachers and the American Physical Society: The American Journal of PhysicsThe Physics TeacherThe Journal of Physics Education ResearchPhysical Review Special Topics - Physics Education ResearchOther journals in which articles of interest may be found include:Physics Education, a journal published in Great Britain, regularly includes interesting papers on demonstrations and other topics of current interest.The Journal of Chemistry Education regularly includes articles dealing with demonstrations common to both physics and chemistry.Journal of College Science Teaching, published by the National Science Teachers Association, includes articles in Education Research having common interest among the sciences.Journal of the National Science Teachers Association contains mostly articles of more general interest.The Science Teacher, published by the National Science Teachers Association (NSTA), deals with high school level science in general, so physics is a smaller component than in the above journals.The Scientific American including Jearl Walker “Amateur Scientist” columns (also available on CD; see below).Professional web sites and conferencesWeb sites of interest are provided by a variety of professional and commercial concerns. The AAPT web site now has direct web links to virtually all articles in the history of the American Journal of Physics and The Physics Teacher, available to all members of the AAPT. , The American Association of Physics Teachers web site.

Some articles from these conferences will be found on various web sites; see section on Physics Education Research. (A), Journal of Research in Science Teaching, Wiley Online Library. (A)Workshops for teachers, AAPT New Faculty Workshop. Quoting from the AAPT Workshop announcement: “Since 1996, the American Association of Physics Teachers has sponsored workshops designed to help new faculty at research and four-year institutions understand how to become more effective educators and support their quest to gain tenure.” These workshops, available to tenure track faculty at research an four-year institutions at the nomination of your department chair, cover material that is important in development of teaching techniques for younger faculty. Summaries of the materials covered in the workshops will be found on the web site, including recent developments in Physics Education Research. (A)“AAPT Summer Meeting Lecture Demonstrations Workshop.” In the two days prior to the Summer Meeting of the American Association of Physics Teachers (AAPT), the Physics Instructional Resource Association (PIRA) presents a workshop on lecture demonstrations, open to all interested individuals attending the meeting. The workshop generally presents the “PIRA 200,” a collection of 200 of the most important demonstrations used in the teaching of physics. In addition to showing the actual demonstrations as used by the presenters at their institutions, the workshop provides lots of ancillary material for use with the demonstrations as well as information regarding how to obtain or construct your own demonstrations. These workshops are very informational, especially for the beginning teacher or demonstration professional, and are highly recommended. (I), At the AAPT Summer Meeting, held in a different American city each summer, many workshops are held in the two days preceding the meeting. The range of workshops offered is different each year; generally a group of workshops covering the more important topics to physics high school and/or college teachers, such as modeling, interactive physics lecture demonstrations, or tutorials, may be offered. See the AAPT Conferences web page for details. Workshops are often available at sectional AAPT meetings, but the selection may be more limited. (I), Modeling Instruction in High School Physics, Physical Science, Chemistry, and Biology, Arizona State University. This is an annual workshop, originally designed and led by Professor Hestenes at ASU for high school teachers. Materials for the workshop have been expanded to include physical science and chemistry, and will include biology beginning in 2011. (I), Fundamentals of Inquiry: workshops designed to introduce teachers to inquiry. These workshops often include work with demonstrations; some of the materials in the Exploratorium Snackbooks, as well as some materials on the Exploratorium web site, was produced in these workshops. (E)Books and articles primarily regarding formal classroom lecture demonstrations.Over the years, the topic of physics demonstrations has attracted a large number of authors. Lamentably, many of the excellent early publications are no longer in print. In listing some of these publications here, I wish to recognize that they are worthy of inclusion in any complete Physics Demonstration Facility library, and hope that they will be considered for re-publication by the AAPT, or at least duplicated inexpensively so that they may be available to more interested people. One notable exception is the classic book by Sutton, published in 1938, which has, with urging and support from the Physics Instructional Resource Association, been reprinted by the American Association of Physics Teachers.Included in this collection are a number of books with experiments primarily directed toward the student laboratory. Over the years I have used many of these books as both reference materials and models for how to construct and/or present the experiment as a lecture demonstration.“Resource Letter PhD-1: Physics Demonstrations,” John A. Davis and Bruce G. Eaton, Am. J. Phys. 47, 835-840 (1979). This is the original Resource Letter on Physics Demonstrations. Many of the publications listed in this Resource Letter are still of great current interest, and may be included in the current version. Items that may be less current or unavailable may be left out of the current list, so individuals interested in some of this earlier work should peruse Resource Letter PhD-1 for completeness. (I)Demonstration Experiments in Physics, Richard Manliffe Sutton (American Association of Physics Teachers, College Park, MD 20741-3845, 2003). In addition to being an excellent source of physics demonstration ideas, this is one of the earliest and most important English books on physics demonstrations, and remains a classic. The original, sponsored by the American Association of Physics Teachers and published by McGraw-Hill in 1938, was at long last reprinted in 2008 by the AAPT, and is available once again. The textual material is accompanied by a limited number of very helpful drawings and photographs; this book is an excellent source of ideas and inspiration. Over the years I have obtained much inspiration and many excellent ideas from Sutton. I very strongly recommend that every demonstration facility and physics teacher have a copy in their library. (I)Physics Demonstration Experiments, Volumes 1 and 2, Edited by Harry F. Meiners, sponsored by the American Association of Physics Teachers (The Ronald Press Co. for the AAPT, New York, 1970). This set of two excellent reference books remains a necessity for all physics demonstration libraries. It includes over 1100 demonstrations, with over 2200 photographs and drawings. Much of the equipment for these demonstrations is described in great detail, along with circuits and some machine shop sketches. Although some of the electronics has become outdated, the book remains among the most complete guides to construction of physics demonstrations. I have obtained many useful ideas from Meiners, and have found it immensely helpful for both conceptual and construction ideas. (E,I)A Demonstration Handbook for Physics, Second Edition, George D. Freier and Frances J. Anderson (American Association of Physics Teachers, Stony Brook, New York, 1971, 1981). This is one of the basic manuals that should be found in every physics demonstration facility library and on every physics teacher’s bookshelf. It contains a large number of demonstrations in outline form, using stick figures and simple drawings to illustrate the principal features of the demonstration. Although the discussions are very brief, one can quickly leaf through the information and easily get lots of good ideas. (E)Selective Experiments in Physics: General Instructions, Mechanics, Heat, Light, Electricity, Sound, and Nuclear Physics, authored by various combinations of: C. J. Overbeck, R. R. Palmer, R. J. Stephenson, and Marsh W. White, V. E. Eaton, Miles J. Martin, and Ralph S. Minor (Central Scientific Company, Chicago, 1940-1964) This is a collection of almost 300 classic demonstrations using equipment available up through the 1970s from CENCO, consisting of individual sheets that occupy three large binders. Some of this equipment is now unavailable, and some is outdated, but the discussions in much of this work remain both classic and helpful. Each demonstration listed has a discussion of the apparatus and the object of the demonstration; most include drawings and equations at the engineering physics level. (E)Although it is long out of print, many demonstration descriptions are now available in PDF format on the CENCO web site: to the individual demonstration descriptions are preceded by this introduction:From the 1940s through the 1970s, Cenco (later known as Central Scientific) published 298 selective science experiments geared to college physics courses. Of course, the firm hoped instructors would purchase Cenco lab equipment to conduct the experiments, but the directions, diagrams, and photographs provided invaluable assistance to any physics ics include Mechanics, Heat, Light, Electricity, Sound, Nuclear Physics, and General Instructions. From the photocopies foreword: Clearly written with diagrams, illustrations and mathematical formulas.Exploratorium Cookbook, Volume One: A Construction Manual for Exploratorium Exhibits, Raymond Bruman and the Staff of the Exploratorium (The Exporatorium, San Francisco, California, 1991). This book includes instructions for building 82 exhibits related to light and images; vision; sound and hearing; electricity and magnetism; color; mechanics; and patterns. (E)Exploratorium Cookbook, Volume Two: A Construction Manual for Exploratorium Exhibits, Ron Hipschman and the Staff of the Exploratorium (The Exporatorium, San Francisco, California, 1990). This book includes instructions for building 52 exhibits related to light and images; plant and animal behavior; electricity and magnetism; heat and temperature; the physics of sound; mechanics; exponentials; patterns; and vision. (E)Exploratorium Cookbook, Volume Three: A Construction Manual for Exploratorium Exhibits, Ron Hipschman and the Staff of the Exploratorium (The Exporatorium, San Francisco, California, 1993). This book includes instructions for building 67 exhibits related to electricity and magnetism; light; sound, speech, and hearing; vision; heat and temperature; mathematics and patterns; mechanics; and neurophysiology. (E)The above three “cookbooks” describe demonstration experiments that have been constructed and used as hands-on materials at the Exploratorium in San Francisco. I have used these plans to construct demonstrations that are useful both for hands-on activities as well as actual classroom and lecture hall demonstrations. They provide a wealth of excellent practical advice, and are strongly recommended. (E)The Exploratorium Science Snackbook (Exploratorium Teacher Institute, San Francisco, California, 2011). This book was created as a collection of work of attendees at the Exploratorium Teacher Institute. It contains over 100 science activities of a slightly simpler and less formal nature than the cookbooks, covering many basic areas of physics. This one is particularly good for make-and-take projects and demonstrations that can be made more easily by less experienced teachers with more readily available materials. (E)HANDS-ON SCIENCE: A Teacher's Guide to Student-Built Experiments and the Exploratorium Science Snackbook: The Exploratorium Science Snackbook: what it is and how you can use it, Paul Doherty (The Exploratorium, San Francisco, California, 1993, 1994, 1995, 1996). Several articles on how to use the Exploratorium Snackbook along with some nice examples of “snacks.” Samples of the book contents will be found on the web site: . (E)Exploratorium Snacks. (The Exploratorium, San Francisco, California, 2011). This site is a “book” containing direct links to over 110 “snacks,” each of which includes complete information about their construction and use, along with lots of related comments. For quick information about simple demonstrations, you can’t beat this page: . Also given is a link to the page where you can order a hard copy of the book. (E)Apparatus for Teaching Physics: Reprints of Articles from THE PHYSICS TEACHER April 1963 – December 1971, Committee on Apparatus for Educational Institutions (American Association of Physics Teachers, College Park, Maryland 1972). This compilation includes almost 300 titled segments, with each segment containing at least one classroom demonstration. Although all of the ideas in the book can be found as articles or notes in Apparatus for Teaching Physics columns in THE PHYSICS TEACHER, the convenience of finding them in a single source with an excellent index is very helpful. Many of the demonstrations have photographs or drawings, and in some cases they are accompanied by letters regarding the demonstrations submitted after publication, detailing some of the issues in the demonstrations and allowing correction of errors. This is a nice book, if you can get it. (E)A Potpourri of Physics Teaching Ideas, Edited by Donna Berry Conner (The American Association of Physics Teachers Publications Department, 1987). This book contains reprints of articles regarding demonstrations taken from THE PHYSICS TEACHER over the period April 1963 to December 1986. Many physics demonstration topics are included; in addition a large number of other articles describe various aspects of construction and use of demonstrations. The book is a convenient way to have lots of ideas regarding demonstrations and their use readily at hand. (E)Apparatus for Teaching Physics, Edited by Karl C. Mamola (American Association of Physics Teachers, College Park, Maryland, 1999). This is a collection of reprints of articles from Apparatus for Teaching Physics columns from THE PHYSICS TEACHER over the period from 1987-1998. This book continues the helpful and convenient tradition of having selected sets of articles on demonstrations such as those contained in this book and the previous two entries. (E)Interactive Physics Demonstrations, Joe Pizzo (American Association of Physics Teachers, College Park, Maryland, 2001). This book contains 46 physics demonstration experiments first published in Deck the Halls columns of THE PHYSICS TEACHER from 1972 to 2001. These demonstrations are not only useful for your class, but also as hands-on experiments in the classroom or hallway exhibits. (E)Physics Demonstration Experiments at William Jewell College, Wallace A. Hilton (William Jewell College, Liberty, Missouri, 1971). During the 1960s and 1970s, Wallace Hilton was one of the great early proponents for high quality physics lecture demonstration and laboratory equipment. He authored many articles in physics journals as well as several books published by William Jewell College regarding his work. I have found the materials that he describes in his publications of the highest quality, and very helpful in the development of University of Maryland Lecture-Demonstration Facility materials. This book includes about 300 demonstrations with lots of photographs and drawings, along with a collection of journal reprints. I strongly recommend this book as well as several others that Professor Hilton produced. (E,I)Physics Demonstrations: A Sourcebook for Teachers of Physics, Julien Clinton Sprott (University of Wisconsin Press, Madison, Wisconsin 53711, 2006). This is an excellent book, with a collection of 85 demonstrations, covering most areas of physics, ideal for use in either the classroom or public programs. Professor Sprott has used these demonstrations as the basis for a series of very successful public programs, The Wonders of Physics, which has run continuously since 1984. The book includes details about the construction of the demonstrations, concise explanations of the ideas that the demonstrations illustrate, information about sources of materials, comments about the possible pitfalls and dangers that may arise during their use, and insight into Professor Sprott’s unique staging and humor. A DVD set showing all of the demonstrations is included with the book, and additional DVDs of all of the Wonders of Physics programs are also available from the University of Wisconsin (See section on demonstration videos.). (E)The Dick and Rae Physics Demo Notebook, D. Rae Carpenter, Jr. and Richard B. Minnix (DICK and RAE, Inc., Lexington, Virginia, 1993). This is a collection of around 600 demonstrations made popular by Dick and Rae through a long-standing series of summer demonstration workshops held at the Virginia Military Institute in Lexington, Virginia. It contains good experiments, good explanations, and clear drawings and photographs, and should be on every demonstrator’s bookshelf. (E)String and Sticky Tape Experiments, Rodney D. Edge (American Association of Physics Teachers, College Park, Maryland, 1987). This book contains instructions for construction of physics demonstrations using almost no materials – at least not expensive materials. There is a great deal of charm in actually using common items to illustrate the great concepts of physics. I used this book in teaching a seminar on demonstrations to perspective high school physics teachers, and was very surprised and pleased that how many physics toys and experiments could be clearly demonstrated using these basic materials. Neat book, especially for the high school teacher with little or no equipment budget who needs a quick and inexpensive demonstration on regular occasion. (E)A Demo A Day: A Year of Physics Demonstrations, Borislaw Bilash II and David P. Maiullo (Flinn Scientific, Inc., Batavia, IL 60510, 2009). This is a very nice, recent contribution to the demonstration profession, aimed at the high school physics teacher who is “a first-year novice, full of enthusiasm and seeking to become the best physics teacher possible,” and who has lots of ambition, but “limited experience in building equipment and performing demonstrations.” As such, the book provides lots of demonstrations, lots of information regarding how they are constructed or otherwise put together, and very helpful hints, unique to each demonstration, regarding use of the demonstration in class. The authors have substantial experience with use of demonstrations; I would recommend this book for any teacher, including those with some experience. (E)How Things Work, H. Richard Crane (American Association of Physics Teachers, College Park, Maryland, 1992). This book is a collection of “How Things Work” columns from The Physics Teacher over the period 1983-1991. It includes explanations for over 65 devices from that period that use physics or technology in a neat way, along with suggested experiments using the apparatus being discussed or that illustrate the physics concepts involved. Although it is twenty years old, it contains lots of good ideas for class discussion and for individual homework assignments. (E)How Things Work, Louis A. Bloomfield (John Wiley and Sons, Inc., New York, 1997). This is the excellent book written for use in the general education physics course How Things Work by Professor Bloomfield at the University of Virginia. It includes enough topics to keep you busy for a few years; most topics are accompanied by suggestions for classroom demonstrations and other activities for classroom discussion. If you do not offer the class How Things Work at your University, you should consider it, and then develop neat demonstrations to enhance your interest and the excitement of the students. An Instructor’s Manual is available from the publisher. (E)How Everything Works: Making Physics Out Of the Ordinary, Louis Bloomfield (John Wiley and Sons, Inc., New York, 2008). This is a 720 page extension – from things to everything - of Bloomfield’s earlier book, How Things Work. It seems to be written as much for more informal physics reading as for physics classes, and it adds a large number of topics. It covers a huge number of topics, with lots of figures and an informal yet very informative approach. This book is an excellent supplement to the previous text. (E)Chemical Demonstrations : A Handbook for Teachers of Chemistry, Volume 1, Bassam Z. Shakhashiri (University of Wisconsin Press, Madison, Wisconsin, first edition, 1983)Chemical Demonstrations : A Handbook for Teachers of Chemistry, Volume 2, Bassam Z. Shakhashiri (University of Wisconsin Press, Madison, Wisconsin, first edition, 1985)Chemical Demonstrations : A Handbook for Teachers of Chemistry, Volume 3, Bassam Z. Shakhashiri (University of Wisconsin Press, Madison, Wisconsin, first edition, 1989)Chemical Demonstrations : A Handbook for Teachers of Chemistry, Volume 4, Bassam Z. Shakhashiri (University of Wisconsin Press, Madison, Wisconsin, first edition, 1992)Chemical Demonstrations : A Handbook for Teachers of Chemistry, Volume 5, Bassam Z. Shakhashiri with Rodney Schreiner and Jerry Bell (University of Wisconsin Press, Madison, Wisconsin, first edition, 2011).These five volumes, containing a total of about 2000 demonstrations, are the most extensive set of books of chemistry demonstrations. Bassam Z. Shakhashiri, Professor of Chemistry at the University of Wisconsin, was Assistant Director of the National Science Foundation for Science and Engineering Education from 1984 to 1990. The first four volumes are written more for chemistry teachers, while the fifth volume, with its focus largely light and color, is also aimed more at the general population of chemistry demonstration lovers. It has sections on the eye and chemical processes in the human visual system. I have found this series very useful in helping to explain many physics demonstrations that are also used in chemistry, in offering alternate ways to present and to discuss the demonstrations. Educational Innovations sells these Shakhashiri books as well as eleven videos of his annual chemistry demonstration program, “Once Upon a Christmas Cheery in the Lab of Shakhashiri.” I recommend these books as part of your demonstration library. (E)Physical Principles of Electricity and Magnetism, R. W. Pohl, translated into English by Winifred M. Deans (Glasgow, Blackie, and Son, London, 1930).Physical Principles of Mechanics and Acoustics, R. W. Pohl, translated into English by Winifred M. Deans (Glasgow, Blackie, and Son, London, 1932).Einführung in die Physik, Robert Wichard Pohl (Springer-Verlag, Berlin, 1930-present). These books, in the original German, comprise a three-volume series that describes many of the demonstrations using the classic equipment available from Klinger Educational Equipment up through the 1980s. Although this equipment is largely no longer available, the quality of the equipment and the related literature is so substantial that the books are well worth reading if you have reasonable familiarity with German. At least two of the books have been translated into English, as listed above. (E,I)Novel Experiments in Physics – a selection of laboratory notes now used in colleges and universities, Walter R. French, Jr., John G. King, Harry F. Meiners, W. C. Kelly, H. V. Neher, Alan M. Portis, Howard P. Stabler, Allan M. Sachs (Sponsored by the Committee on Apparatus for Educational Institutions of the American Association of Physics Teachers, Published by the American institute of Physics, New York, 1964). This 450 page book contains reprints and preprints of articles from the American Journal of Physics as well as less formal laboratories used at a number of universities in the U.S. While this book describes use of equipment in laboratories at the level of engineering physics, much of the equipment is useful at this time as classroom demonstrations. About eighty experiments are included, each including drawings or pictures, circuit diagrams where appropriate, and excellent information and analysis of the experiment. (I)Novel Experiments in Physics II – a selection of laboratory notes now used in colleges and universities, F. E. Christensen, Ronald Bergsten, Sabinus H. Christensen, Ernest Coleman, Harold A. Daw, Robert H. Johns, and John H. Miller III (Sponsored by the Committee on Apparatus, American Association of Physics Teachers, Stony Brook, New York, 1975). This is a continuation, by popular demand, of the first Novel Experiments in Physics, published in 1964. The second book is about 500 pages in length and contains an additional 45 experiments. (I)Experiments in Physics, second edition, Wallace A. Hilton (William Jewell College, Liberty, Missouri, first edition, 1967, second edition, 1971). This book contains descriptions of about forty experiments useful in laboratories at William Jewell College; many of the experiments are very useful as lecture demonstrations in either engineering or non-calculus physics classes. Each experiment includes photographs of the apparatus (some of which use outdated equipment) as well as nice analyses, which are useful in preparing lectures in which the experiment would be carried out as a demonstration. Experiments include mechanics, heat, sound, electricity and magnetism, optics, and atomic and nuclear physics. (I)Physics Experiments and Projects: Volume 1. Properties of Materials, W. Bolton (Pergamon Press, Ltd., Oxford, England, 1968).Physics Experiments and Projects: Volume 2. Waves and Particles, W. Bolton (Pergamon Press, Ltd., Oxford, England, 1968).Physics Experiments and Projects: Volume 3. Atomic Physics, W. Bolton (Pergamon Press, Ltd., Oxford, England, 1968).Physics Experiments and Projects: Volume 4. Electricity, W. Bolton (Pergamon Press, Ltd., Oxford, England, 1968).The above set of four small books was written to guide students at the High Wycombe College of Technology and Art in a discovery type physics laboratory course: After going through the experiments, the theory evolves as a discussion of the results. The descriptions are short and sketchy, with the student laboratories preceded by a brief classroom discussion of the physical concept. The experiments are neat, and the format is similar to but less detailed than the physics “inquiry” manuals now being used in many laboratories. These labs would certainly serve as a good set of ideas for inquiry learning laboratories at the intermediate level, and would also be useful in suggesting inquiry learning ideas for classroom demonstrations. (E)Demonstrations and Experiments for Physics, John M. Fowler (Washington University, St. Louis, Missouri, 1964). This is a very thoughtfully done summary of materials used for a new two-year general physics course at Washington University, carried out with an NSF grant by John M. Fowler and E. D. Lambe from 1962-1964. It includes a number of nice demonstrations, including a relatively inexpensive phase-locked six-harmonic Fourier synthesizer, along with labs and other areas for discussion. Professor Fowler was important in the early development of the American Association of Physics Teachers and the Commission on College Physics. (E)The Lloyd William Taylor Manual of Advanced undergraduate Experiments in Physics, Thomas Benjamin Brown, Editor-in-Chief (Addison-Wesley Publishing Company, Reading Massachusetts, 1959). This book includes experiments in virtually all areas of physics at the upper undergraduate level. Many of the experiments are readily adopted to demonstrations, and can be used in lower level physics courses, and the book is also very useful in understanding the experiment in depth without going to a graduate or post-graduate text. Explanations include lots of drawings, with equations when appropriate. (I)Experiments in Physics, sixth edition, Leonard Rose Ingersoll, Miles Jay Martin, and Theodore Alton Rouse (McGraw-Hill Book Company, Inc., New York, 1953). This book includes discussions of about 80 upper level physics experiments, along with an informative section on physics apparatus in general. Areas covered are A. mechanics, B. Heat, C. Electricity and Magnetism, D. Wave Motion and Sound, and E. Light. Many of these experiments are useful as lecture demonstrations, and the book provides helpful insight into the background and uses of the devices, generally at the level of engineering physics. (I)Apparatus Drawings Project, Robert G. Marcle, Sponsored jointly by the American Association of Physics Teachers and the American Institute of Physics (Plenum Press, New York, 1962). This is an excellent, but dated, book with drawings and suggestions for construction of thirty experiments. Although the tube type electronics is now virtually obsolete, this book does illustrate the care and thought process that must go into the design and fabrication of a demonstration to achieve its greatest impact. Many of the demonstrations remain basics for a well rounded demonstration facility. This book provides a good template for development of quality demonstrations, so a modern version of this book would be an excellent contribution to the demonstration community. (I)Building Scientific Apparatus, John H. Moore, Christopher C. Davis, and Michael A. Coplan (Addison-Wesley Publishing Company, Reading, Massachusetts, 1983). This book contains a large number of basic hints about parts and materials with which you must be familiar if you build demonstration apparatus from scratch. Included in its 480 plus pages are sections on virtually every technique required to construct demonstrations, which would be especially helpful for those with limited access to experienced machinists and technicians. Also included are hints about how to get the most out of your apparatus once it is built, including handling of noise and other electrical issues. These topics are discussed as part of a more general discussion of several issues, such as vacuum technology, optical systems, and data acquisition, with a lot of physics thrown in. If you are developing demonstrations in one of the areas discussed, it is worth reviewing. (I,A)The Overhead Projector in the Physics Lecture, Walter Eppstein (Rensselaer Polytechnic Institute, Troy, New York, 1962) This short booklet, an internal publication of RPI, was written by a professor obviously very adept at the using the overhead projector and very clever at developing some of the early demonstrations using it. Although it is largely out of date, small demonstrations sold by some of the current Japanese manufactures are bringing back use of the overhead projector. In some demonstration facilities it is actually emerging as a more useful and less expensive device to provide simple demonstrations in large lecture halls. (E)Optics Demonstrations with the Overhead Projector, Douglas S. Goodman (Optical Society of America, 2000). This is a substantial spiral-bound book with 350 pages, showing that use of the overhead projector in physics teaching is still alive and well. It contains a large number of interesting demonstrations covering most areas of classical optics; because the equipment can be small compared with lecture-size apparatus, cost and storage can be minimized. The Optical Society of America and SPIE, an international society advancing light-based research and education, sponsor a number of efforts in teaching of optics, including workshops and publications at all levels. (E,I)“Science and Fun in a ‘Magic Show of Light,’” in Optical Demonstrations on an Overhead Projector for elementary school students, Joe J. Lones, Nadezhda K. Maltseva, and Kurt N. Peterson, (SPIE, 2007). This is a very detailed and informative article describing use of the book Optics Demonstrations with the Overhead Projector in presenting a program for elementary school students. On the web at: (E)Experiments and Demonstrations in Physics: Bar-ilan Physics Laboratory, Yaakov Kraftmakher (World Scientific Publishing Co. Pte. Ltd., Singapore, 2006). The author describes demonstrations and laboratories at the Bar-ilan University. With over 500 pages, this is a relatively complete book, using mostly Pasco Scientific equipment for both lecture demonstrations and laboratories. Also included is a section on student projects. A paperback is available. (E,I)Physics in 700 Experiments, Michael J. Higatsberger, Translated from the original German by Peter D. Potter (Blick in die Welt, Frankfurt, Germany, 1981). This book includes 713 physics experiments covering most areas of physics. It is unique in that it provides interesting variants of the experiments, such as determination of the caloric value of nutrients, and applications that are generally left out of most texts of this type, but make the concepts really relevant and very interesting. If you want mainstream concepts, with interesting asides and some different ideas for illustrating these concepts, both for the demonstrations that you use in your teaching and in your physics demonstration programs, you will get lots of ideas from this book. (I)700 Science Experiments for Everyone – Revised and Enlarged Edition, compiled by the United Nations Educational, Scientific, and Cultural Organization (Doubleday & Company, Inc., Garden City, New York, 1956, 1962). This book contains 700 experiments in science, many of which deal with physics. The expressed purposes of the book include teacher training, sourcebook for science teachers, basis for workshop study in science teaching, and ideas for assembling a collection of science materials and kits. As such, it contains a substantial section on sources of materials, and a section on the psychology of science teaching and learning. The demonstration descriptions are short, and explanations of the science are generally not included. (E)Turning the World Inside Out and 174 Other Simple Physics Demonstrations, Robert Erlich (Princeton University Press, Princeton, New Jersey, 1990). This book describes classroom demonstrations that can be developed and performed in class, even at the University level, with a minimum of effort and expense. Many of these are ways to do classic demonstrations in a simpler way, or adding some interesting sidebar to the demonstration. Erlich discusses his philosophy of demonstrations, gives an extensive table showing how you can keep down the cost of the equipment, and generally provides commentary on the experiments. Lots of reference material is presented, along with tips for use of the demonstrations in class. (E)Why Toast Lands Jelly-Side Down: Zen and the Art of Physics Demonstrations, Robert Erlich (Princeton University Press, Princeton, New Jersey, 1997). This book describes how to design and build your own physics demonstrations equipment, the Erlich provides a large section on his philosophy of what makes a good (or bad) demonstration and how demonstrations can be used most effectively in class. After a thorough 20-page discussion of philosophy, Erlich uses the next 170 pages to describe demonstrations that he has constructed and used following his philosophy. He also provides a nice bibliography of physics demonstration books. Both of Professor Erlich’s books are well worth having available for teaching ideas. (E)Clouds in a Glass of Beer: Simple Experiments in Atmospheric Physics, Craig F. Bohren (John Wiley & Sons, Inc., New York, 1987). This book is a compilation of demonstrations that Professor Bohren developed while teaching a university course in meteorology, and was revised from various publications that he wrote with a co-author between 1981 and 1987. While the demonstrations are generally useful at the elementary physics level, the depth into which the explanations go and the sophistication of some of the concepts involved make the book useful for discussions even at the graduate physics level. No matter the level, you will find this book very interesting and challenging. (I) The Complete Collection of THE AMATEUR SCIENTIST on CD-ROM: Science Fair Edition (Bright Science; CDR edition, 2006). This outstanding CD-ROM contains all of the Amateur Scientist articles from the 1950s through 1999, including articles by Albert Ingalls, C. L. Stong, Jearl Walker, and Forrest Mims, and the complete Amateur Scientist article index from 1928 to 1999. If you are interested in possible science fair projects, or just interested in reading about interesting physics, this is an excellent place to start. (E)The Flying Circus of Physics With Answers, Jearl Walker (John Wiley & Sons, New York, 1977). Note: an earlier version without answers was published in 1975. This is a collection of over 600 “questions” regarding the application of physics concepts to things that most of us experience at one time or another in our daily lives. Although many of the questions are rather complicated, important physical laws and ideas can be identified as relevant or critical in their explanation; this book guides us in our inquiry regarding these phenomena. It includes short answers for each problem, backed up by over 1600 references from physics and other journals. This is an excellent source of ideas for discussion, among parents and children, curious people of all ages, and teachers trying to interest their students in physics and show how physics is relevant to the real world. This book should be in every physicist’s library. (E, I)Ink Sandwiches, Electric Worms, and 37 Other Experiments for Saturday Science, Neil A. Downie (The Johns Hopkins University Press, Baltimore, Maryland, 2003). This unusual book contains 39 unusual, perhaps even off-beat physics and engineering demonstrations, organized into twelve sections that the author has used in an educational outreach program called the Saturday Activity Centre. Each demonstration discussion contains nice sketches and/or electrical circuit drawings, along with a description of the demonstration, explanation of the science involved, hints for using it successfully, references, and a clever quote that you can use in your accompanying PowerPoint slide show. This book is worth having for the uniqueness of its ideas. You will have to read the book to find out what an ink sandwich is. (I)Physics Can Be Fun, Y. Perelman, translated from the Russian by Arthur Shkarovsky (Mir Publishers, 1986). This unique book has many experiments that you can carry out without lots of equipment, with lots of very interesting applications of the basic ideas to historical issues, with chapters on a variety of physics concepts that we meet in everyday life. Some of these topics include extrapolations of the basic concepts to include illusions, perpetual motion machines, and tricks that were used to verify religious “miracles” in bygone ages. (I)101 Classroom Demonstrations and Experiments for Teaching Physics, David Kutliroff (Parker Publishing Company, Inc., West Nyack New York, 1975) David Kutliroff has collected the most effective and reliable physics demonstrations from his experience as a high school physics teacher and his work on the staff of the Summer Institutes for High School Physics Teachers at Rutgers University, making use of equipment normally found in the average high school physics supply room. He includes hints on how to use the demonstrations most effectively and some of the issues that might arise in their use. The book is well illustrated and includes a nice index. (E)Invitations to Science Inquiry, Second Edition, Tik L. Liem (Science Inquiry Enterprise, 1990). This is a large book, containing over 350 demonstrations of physics as well as other sciences that are appropriate for middle school and high school. The demonstrations are accompanied by clear instructions and suggested teacher questions. It is a good book to have as a reference for quick and solid ideas. (E)Hands-On Physics Activities with Real-Life Applications: Easy-to-Use Labs and Demonstrations for Grades 8 – 12, James Cunningham and Norman Herr (The Center for Applied Research in Education, 1994). One of the two-part PHYSICAL SCIENCE CURRICULUM LIBRARY, along with a similar book on chemistry. Contains over 200 demonstrations and experiments with detailed descriptions. (E)Physics Demonstrations, Edited by Shoma Kutasov (Penn Books, Los Angeles, 1978). This book includes over 300 demonstrations covering most areas of physics; each demonstration includes a sketch or drawing and a very brief statement of what it does; no detailed discussion of the demonstration in action or explanation of why it works is included. While these demonstrations formed the nucleus of the demonstration experience for Soviet high school physics students in the time period around 1960-1970, more explanation is necessary for this book to achieve optimum usefulness for many current physics teachers. It assumes that the teacher has a significant amount of physics demonstration equipment at his or her disposal. (E)Optics Experiments and Demonstrations, C. Harvey Palmer (The Johns Hopkins University Press, Baltimore, Maryland, 1962). This 320 page book contains about 59 demonstration experiments along with information on their construction and use, with appropriate use of mathematics when it is helpful. Basic areas include ray optics, wave optics, polarization and crystal optics, and spectroscopy. The discussion with each demonstration is well chosen. (I)Experiments in Optical Physics third edition, Wallace A. Hilton (William Jewell College, Liberty, Missouri, first edition, 168, second edition, 1969, third edition, 1974). This book contains about 70 experiments in all areas of optics, used in laboratories and independent study projects at William Jewell College, but many of which are imminently usable as demonstrations in general physics as well as intermediate optics classes. There are lots of apparatus photographs, hints about how to successfully set up the apparatus, and guides to their analysis. A very nice feature of this book is the list of about 240 references covering optics, teaching of optics, and sources of optics equipment (many of which still exist). (I)Teaching light & Color, Edited by Thomas D. Rossing and Christopher J. Chiaverina (American Association of Physics Teachers, College park, Maryland, 2001). This book is an outstanding source of ideas for teaching courses in light and color, containing a large number of papers reprinted from the The Physics Teacher, Physics Today, Jearl Walker’s The Amateur Scientist column in The Scientific American, and others. Also included are the American Journal of Physics Resource Letter TLC-1: Teaching light and color and an extensive set of color prints. This is an excellent source of ideas to use in a light and color course. (E)Exploring Laser light, T. Kallard (Optosonic Press, New York, 1977). This book includes nearly 300 pages, with about 150 titles in the table of contents. It covers literally any imaginable optics demonstration that can be done with a laser, with excellent sketches, photographs where helpful in visualizing many optical phenomena, and lots of helpful information on a range of topics in geometrical optics, physical optics, and holography. It also includes a list of vendors for optical equipment, a very inclusive bibliography, and an excellent index. This is another book that can be very helpful in setting up demonstrations for classroom or lecture use. (I)Science Fun Experiments in Optics, Logix Enterprises Ltd., Montreal, Quebec, Canada, 1972). This is a very nice book, at the high school or amateur scientist level, with 136 optical activities, many of which involve a good bit of sophistication; the book originally came with a kit of optical components, but is of interest on its own. It describes a large number of optical illusions and tricks, lenses, photography, eyesight and correction with eyeglasses, and other optical instruments. This book contains lots of neat stuff! The company still exists; one of their items is a working model of an early computer that they call the “Old Computer Museum.” (I)Liquid Crystal Devices, Edited by Thomas Kallard (Optosonic Press, New York, 1973). If you are interested in liquid crystals and liquid crystal devices, this is the book for you. Included are papers on virtually any liquid crystal application at the time, a list of patents and patent holders, and a bibliography with over 1100 entries. An excellent set of indexes is also provided. (A)Experiments in the hearing and Speech Sciences, Barry Voroba, Ph. D. (Starkey Laboratories, Inc., Eden prairie, Minnesota, 1978). This book provides background information and about 66 demonstrations providing a thorough experimental basis for the study of audiology at the undergraduate level. The book is written for use with the Starkey laboratories Hearing Science Laboratory, a piece of demonstration equipment that is very useful in a class such as introductory Physics of Sound. However, many of the experiments can be done without the basic Starkey equipment, and perusal of this book gives an instructor a significant background in some of the important issues in the psychophysics of sound. I have used the Hearing Science Laboratory device and this manual for years in a class on the Physics of Music at the University of Maryland, and strongly recommend it to other instructors. (E)Experiments on an Air Track, T. Walley Williams, III (The Ealing Corporation, Cambridge, Massachusetts, 1969). Contains eleven demonstration experiments, with information on their setup and analysis. (E)Experiments on an Air Table, George Marousek and T. Walley Williams, III (The Ealing Corporation, Cambridge, Massachusetts, 1969). Contains a nice section on experimental techniques, with twelve demonstration experiments and hints for performance and analysis. This should be a helpful book for those using interactive demonstration techniques. (E)An Experimental Introduction To kinetic Theory, Harold Daw (The Ealing Corporation, Cambridge, Massachusetts, 1974). This is the original booklet that came with the air table to describe its set of kinetic theory demonstrations. It includes discussion of the photographic techniques (basically the same today but with better, digital cameras), analysis of the photography, and a large number of photographs taken with the apparatus described. This could be helpful in developing the equipment for use as a classroom demonstration. (E)Similarities in Wave Behavior, Dr. John N. Shive (Bell Telephone laboratories, Incorporated, 1961-1973). Dr. Shive was the inventor of the Shive Wave Machine while he was the Director of Education and Training at Bell Telephone Laboratories. This is truly and outstanding book: I have used it regularly as a source of ideas in explaining wave concepts, and as a source of ideas for demonstrations using the Shive Wave Machine. The wave machine itself is now manufactured by several companies dealing with physics equipment, and has become a staple in demonstrating a large variety of wave phenomena. If you can get a copy, I would strongly suggest that you do so. (E)The Physics of Technology, Bill G. Aldridge, Philip DiLavore, Bruce B. Marsh, John W. McWane, Carl R. Stannard, and Homer Wilkins, Produced by the Tech Physics Project (McGraw-Hill Book Company, New York, 1975). This book contains the set of 27 Physics of Technology units, written largely at the high school or introductory college physics level. Each unit has a description of the system, experiments that can be done to understand some of the physics involved, the design and construction of the apparatus, and questions that can form the basis of further discussion. (E)Hands-On Physics Activities with Real-Life Applications: Easy-to-Use Labs and Demonstrations for Grades 8-12, James Cunningham and Norman Herr (The Center for Applied Research in Education, 1994). This book has about 200 individual activities using everyday examples to illustrate important ideas in physics. Investigations include some problems, with answers, and explanations for the experiments and observations, some of which use mathematics. The principal author has also written a companion book, “Hands-On Physics Activities with Real-Life Applications,” as well as the paperback “The Sourcebook for Teaching Science, Grades 6-12: Strategies, Activities, and Instructional Resources.” (E)Preconceptions in Mechanics: Lessons Dealing with Students’ Conceptual Difficulties, second edition, Charles Camp and John J. Clement (American Association of Physics Teachers, College Park, Maryland, 2010). This book contains 24 lessons in mechanics with the goal of reducing preconceptions and physics myths in favor of experimentally based learning. It includes activities, experiments and quizzes, plus homework assignments with answers, and has an appendix of teaching suggestions. Many of the ideas are useful in a more standard curriculum as well. (E)The following books were written as workshop manuals for the AAPT sub-group of high school physics teachers known as Physics Teaching Resource Agents, or PTRAs. All of the books are currently available from the American Association of Physics Teachers. As such, they are written for teachers who wish to introduce this material using lots of demonstrations and experimental laboratories at the high school level. All of these books include the following materials: interactive activities, background materials and bibliographies, media resources, applications, events for use in physics Olympiads or other competitions, and test questions with answers. After reviewing them, I strongly believe that as a series they should be part of every high school physics teacher’s library; they are useful either as a curriculum on their own or as supplementary material for class built on other texts. Both these books and other books in the PTRA Series section of the AAPT Physics Store may be found at the web page: Teaching About Color and Color Vision: an AAPT/PTRA Workshop Manual, Bill Franklin (American Association of Physics Teachers, 1997). This book includes information, labs, and demonstrations emphasizing the topics of color vision, thin films, and optical activity. It includes a good materials list, bibliography, and assessment questions with answers. (E)Teaching About D.C. Electric Circuits: an AAPT/PTRA Workshop Manual, Earl Feltyberger, James Mallmann, Judy Schmidt and Thomas Senior (American Association of Physics Teachers, College Park, Maryland, 1995). Included are sections with introductory materials and equipment, ideas for presentation, experiment background information, lots of questions in the form of hands-on experiments, and Olympiad events. (E)Teaching About Electrostatics: an AAPT/PTRA Workshop Manual, Robert A Morse (American Association of Physics Teachers, College Park, Maryland, 1992). This book describes how to build and use electrostatic demonstration equipment, including some of the original Franklin devices. It also includes a good bibliography with technology references, and additional activities for students. (E)Teaching About Impulse and Momentum: an AAPT/PTRA Workshop Manual , Bill Franklin (American Association of Physics Teachers, College Park, Maryland, 2004). This book holds a number of hands-on activities and demonstrations of impulse and momentum, and discusses important applications such as automobile safety, rocketry, and gravity “slingshots.” It includes a large section of background material, about a dozen lab activities, and a number of relevant demonstrations with explanations. Several Olympiad events are described, and a nice collection of questions with answers is provided. (E)Teaching About Kinematics: an AAPT/PTRA Resource, Jane Bray Nelson and Jim Nelson (American Association of Physics Teachers, College Park, Maryland, 2000). This book uses interactive demonstrations in a thorough experiment-based study of kinematics. Included are 48 activities, each with analysis, calculations, and questions with answers. (E)Teaching About Lightwave Communications: an AAPT/PTRA Workshop Manual, Mark Davids, R. Stephen Rea and Paul Zitzewitz (American Association of Physics Teachers, College Park, Maryland, 1994). This book includes a nice section on demonstrations and displays, lots of references using technology media, ideas for Olympiad events, and a light wave communication quiz. (E)Teaching About Magnetism: an AAPT/PTRA Workshop Manual, Robert Reiland (American Association of Physics Teachers, College Park, Maryland, 1996). This book covers lots of demonstration experiments in the areas of magnetostatics and electromagnets.Teaching About Energy: an AAPT/PTRA Resource, John L. Roeder (American Association of Physics Teachers, College Park, Maryland, 2008). This book includes lots of interesting and relevant demonstrations and experiments, activities, and problems, and should inform the student about some of the technical aspects of our current world energy issues. Emphasis is on forms of energy and energy transfer, ending with some of the issues that will face the world in the near future. (E)The Role of Toys in Teaching Physics: an AAPT/PTRA Workshop Manual, Jodi and Roy McCullough (American Association of Physics Teachers, College Park, Maryland, 2009). This is a book of nearly 300 pages that includes a large number of toys that can be used as demonstrations and questions to initiate class discussion. I have found in teaching several courses that using toys to demonstrate any physical principle is not only an effective teaching tool, but also acts as a great attention-getter, and I recommend this book as a good source of ideas. (E)Teaching for the First Time: an AAPT/PTRA Resource for the beginning physics teacher, Jan Mader and Mary Winn (American Association of Physics Teachers, College Park, Maryland, 2008). Among other materials, this book provides helpful information regarding use of interactive demonstrations in all areas of the high school physics curriculum, and provides lots of classroom demonstration experiments and suggestions for their use. (E)Exploring Physics in the Classroom: an AAPT/PTRA Manual, George Amann, Jon E. Barber, and Hank J. Ryan (American Association of Physics Teachers, College Park, Maryland, 2005). This book has two major parts: Section 1 is “exploratory,” where classroom demonstrations are used to explore the laws of physics. Section 2 is “practicum,” where laws of physics are applied to real life situations. Nine exploratory units and 12 practicum challenges are presented in the book. Discussion and sample calculations are given for each. (E)The Role of the Laboratory in Teaching Introductory Physics: an AAPT/PTRA Resource, Jim Nelson and Jane Bray Nelson (American Association of Physics Teachers, College Park, Maryland, 1995).this book presents about 30 lab activities with data sheets, including questions for the students to answer during the labs. There are lots of interesting activities; the labs cover statics, mechanics, optics, electricity, magnetism, and more. (E) Inspiration Regarding Teaching with DemonstrationsThe Art and Science of Lecture Demonstration, Charles Taylor (Taylor & Francis Group, New York and London, 1988). This book discusses how to present physics lecture demonstrations, based on the experiences of the author as a distinguished Professor of Physics at University College, Cardiff, Wales. Professor Taylor described his experiences using demonstrations in teaching in the Gregynog Lectures at the University College of Wales, Aberystwyth, during the 1987-1988 academic session, and packaged the content of these lectures into this book. He describes some of the history of demonstration lectures in England at the Royal Institution, discusses in detail what he means by the term “demonstration,” and proceeds to illustrate techniques for use of demonstrations. He includes chapters on topics such as “Controversy about the value of demonstrations” and “The use of drama.” This book is excellent; anyone who wishes to be an outstanding physics lecture demonstrator should be familiar with both the issues and techniques that Professor Taylor discusses. (E,I,A)“Best Practices in Physics Demonstrations,” or “Oh, I thought this was just for entertainment.” Brian A. Pyper, AAPT UT/ID section meeting, Boise, ID, March 2008. Interesting and entertaining slide show with some helpful comments: (I)“The Lecture Demonstration: Try It, They’ll Like It,” D. Rae Carpenter and Richard B. Minnix, Phys. Teach. 19, 391-392 (1981). Encouragement for every physics teacher to use demonstrations as an integral part of their teaching. (I)“Demonstrations as an aid in the teaching of physics,” Wallace A. Hilton, Phys. Teach. 19, 389-390 (1981). A great teacher and demonstrator seeks to inspire other physics teachers. (I)“The lecture demonstrations: A Developing Crisis,” John B. Johnston, Phys. Teach. 19, 393-394 (1981). The author asks for greater support of demonstrations as an integral component of a physics course. (I)“Confessions of a converted Lecturer,” 90-minute recorded seminar by Professor Eric Mazur, as presented to the Perimeter Institute, 10110081, Phys. Teach. 49, 254 (2011). This item in The Physics Teacher “websights” column discusses the presentation and gives links to a text file and a PDF download. (A), A YouTube version of the previous Mazur lecture presented at University of Maryland, Baltimore County campus. (A) “Millikan Award Lecture (1998): Building a Science of Teaching Physics,” Edward F. Redish, University of Maryland, College Park Am. J. Phys. 67, 562-573 (1999). Inspirational summary of the state of science education with lots of provocative examples. . (A)Physics Lecture Demonstrations, with some problems and puzzles, too, compiled and annotated by Donald Simanek. Discussion of demonstration presentations with lots of helpful suggestions and demonstration examples. , (A)How Does A Thing Like That Work?, David G. Willey. This is the home page for Willey, a physics professor at the University of Pittsburgh at Johnstown, Pennsylvania and very popular lecturer. He regularly appears at a large number of public forums, such as the Tonight Show. () Four of his most dangerous demonstrations are explained in an article in the Skeptical Inquirer (Volume 23.6, November/December 1999): information is linked to his home page.Books of demonstrations primarily for informal and pre-high school use.Bet You Can!, Vicky Cobb and Kathy Darling (Avon Books, 1983). Bet You Can't!, Vicky Cobb and Kathy Darling (Avon Books, 1983). These two wonderful books are very appropriate for elementary school students. Bet You Can! includes 62 tricks that, surprisingly, you can do because of the laws of physics; Bet You Can't! includes 82 tricks that, surprisingly, you can’t do because of the laws of physics. We use some of these activities at our yearly University spring open house to entertain small children who came with their parents. I also gave this set of books to my elementary school grandchildren.Demonstrations in Physics, Julius Sumner Miller (Ure Smith, Sidney, Australia, 1969). Julius Sumner Miller was a very popular demonstrator of physics during the 1950s and 1960s. In the 1970s he regularly appeared on the Johnny Carson Tonight Show; I remember staying up late for the Tonight Show so that I could see Professor Miller’s neat demonstrations. His demonstrations are quick, simple, and compelling, and the explanations short and sweet. Lamentably, this book is out of print, but it is available every now and then at used book stores. (E)These two books contain interesting “physics in real life” questions that originally appeared as a daily column in The Australian newspaper; each day would have the answer for the previous day’s question along with a new question for the current day. The questions are interestingly phrased, accompanied by a handwritten “blackboard lecture” type line drawings, and mostly were the sort of thing that inquisitive people had pondered at some time in their lives. These books include some very interesting and well-phrased questions that can be used to enhance a physics lecture at almost any level. (E)Millergrams: Some Enchanting Questions for Enquiring Minds, Julius Sumner Miller (Ure Smith, Sydney, Australia, 1966; Doubleday & Company, Inc. Garden City, New York, 1970). The Second Book of Millergrams: Some More Enchanting Questions for Enquiring Minds, Julius Sumner Miller (Ure Smith, Sydney, Australia, 1966; Doubleday & Company, Inc. Garden City, New York, 1970). Physics Fun and Demonstrations with Professor Julius Sumner Miller, Rocco Blasi (Central Scientific, Chicago, Illinois, 1968). I found this book on Amazon, with no other information than price. It may have other demonstrations than the previous books, or it may be available if the others are not. If you are looking for a book about interesting informal demonstrations, anything about Professor Miller will be a winner. (E)Secrets of 123 Science Tricks and Experiments, Edi Lanners (Tab Books Inc., Blue Ridge Summit, Pennsylvania, 1981). This book emphasizes the type of counterintuitive tricks that are often used as physics demonstrations to get the attention of the class. Most experiments are accompanied by classic drawings that remind me of those in magic trick books in the early twentieth century. It is a fun book, with lots of ideas to keep motivated upper elementary and middle school students well occupied, and provide neat demonstrations to physics and science teachers at the middle school or even high school level. (E)333 Science Tricks & Experiments, Robert J. Brown (Tab Books Inc., Blue Ridge Summit, Pennsylvania, 1984). 333 More Science Tricks and Experiments, Robert J. Brown (Tab Books, Inc., Blue Ridge Summit, Pennsylvania, 1984).These two books contain science experiments that formed the newspaper column “Science for You” that ran in the L. A. Times Syndicate. The author suggests that the experiments, many of which he created, should be challenging for ages up to middle school, and can be both a learning process and provide interesting and fun activities for parents to do with their children. The experiments are interesting and compelling; many are accompanied by short explanations. If you are looking for quick and easy experiments for all occasions, these books should be in your library. (E)200 Illustrated Science Experiments for Children, Robert J. Brown (Tab Books, Blue Ridge Summit, Pennsylvania, 1987). This is a thoughtfully prepared book containing several chapters of experiments in physics, including tricks, projects to build from many areas of interest, and additional chapters on chemistry and biology. Each experiment has an equipment list, a procedure, and a brief explanation of what is happening. Many of these experiments were run in the “Science for You” column of the L. A. Times Syndicate. (E)More Science for You: 112 Illustrated Experiments, Robert J. Brown (Tab Books, Blue Ridge Summit, Pennsylvania, 1998). This is a continuation of the science demonstrations prepared for the “Science for You” L. A. Times column. (E)Physics for Kids - 49 Easy Experiments with Optics, Robert W. Wood (Tab Books, Blue Ridge Summit, Pennsylvania, 1990). The author suggest using this book as a sort of individual optics course, by doing the experiments in order, the earlier being the simpler. There are lots of nice line drawings, good explanations of the experiments, and even some more general history and philosophy about light. Each experiment includes a materials list, suggestions for how to set up the experiment, and a brief explanation. This would make a nice book for an upper elementary student who is interested in light. (E)Gadgeteer's Goldmine! 55 Space-Age Projects, McComb, Gordon, (TAB Books, McGraw-Hill, Inc., 1990) This is a manual with instructions for how to build a collection of electronic devices, including such items as a Tesla coil, Van de Graaff, a zenon strobe, and several laser systems. It is written for the knowledgeable amateur, but contains circuitry that may involve danger as well as ambiguities due to obsolete parts. According to reviewers, these projects should only be undertaken by a mature student who has some familiarity with high-voltage circuitry. (I)The following are three of about ten books constituting the “Janice VanCleave Science for Every Kid” Series. The experiments are relatively simple, generally requiring materials that are found around the house or are easily purchased. Most experiments are accompanied with a motivation, suggestions for performing the experiment, and a brief explanation of the physics involved. The experiments are appropriate for upper elementary school students with guidance from a parent; some make use of simple algebra. (E)Janice VanCleave’s Physics for Every Kid: 101 Easy Experiments in Motion, Heat, Light, Machines, and Sound, Janice Pratt VanCleave, (John Wiley & Sons, Inc., New York, 1981). Janice VanCleave's Magnets: Mind-boggling Experiments You Can Turn Into Science Fair Projects, Janice Pratt VanCleave, (John Wiley & Sons, Inc., New York, 1993). Janice VanCleave's Energy for Every Kid: Easy Activities That Make Learning Science Fun, Janice Pratt VanCleave, (John Wiley & Sons, Inc., Hoboken, New Jersey, 2006). Mr. Wizard’s Supermarket Science: More than 100 fascinating and fun experiments using easy-to-find everyday items. Don Herbert, illustrated by Roy McKie (Random House, New York, 1980). Lots of “classic” science experiments, including many involving physics, with brief explanation of the science. These are particularly appropriate for upper elementary school students with their parents! (E)Entertaining Science Experiments with Everyday Objects, Martin Gardner, Illustrated by Anthony Ravelli (Dover Publications, Inc, New York, 1960, 1981). This book contains about 100 simple and compelling physics experiments that can be done with materials commonly available in the home. It includes a number of classic tricks and illusions, and surprising experiments designed to get the attention of an observer. If you want good ideas to use with your middle school student or as quickies for your physics class, this book is a good choice. (E)Science experiments and amusements for children, Charles Vivian (Dover Publications, Inc., New York, 1963). This book includes about 75 physics demonstrations that can be done with materials that are generally found in most homes. It includes nice photographs of the demonstrations as constructed, and sketches showing how to construct the demonstrations or analyze the situations. The ideas are very usable at the upper elementary school level. (E)Fizz Factor: 50 Amazing Experiments with Soda Pop, Steve Spangler (Wren Publishing, Englewood, Colorado, 2003). The experiments in this book are best done at home and outside, to keep from getting in trouble with your janitorial staff (or your wife or mother, whatever the case may be). Steve Spangler is probably best known for his large set of demonstration videos done on a television station in Denver (listed in the section on videos). He describes compelling, if rather messy, demonstrations, with lots of interesting facts, and brief explanations. The book also includes some interesting reading at the beginning, including the “story” of soda pop, chemicals normally found in the drinks, and perhaps a few reasons to never drink it. Many of the experiments have safety warnings, and he suggests use of goggles, along with a good dose of common sense. (E)Tons of Scientifically Provocative and Socially Acceptable Thins to Do with Balloons under the Guise of Teaching Science, Glenn McGlathery and Larry Malone (Teacher Ideas Press, A Division of Libraries Unlimited, Inc., Englewood, Colorado, 1991). The title sort of says it all here; this book is certainly useful if you want your elementary school students to pay attention, and probably for things like scouting merit badges, birthday parties and University Open Houses that attract elementary school children. It does in fact contain 83 interesting and compelling physics experiments, along with simple explanations and comments calling attention to the actual physics principles involved. The authors provide correlation tables with the appropriate grade level (K-6) for each experiment, provide lists of the concepts involved, and relate the experiment to the chapter in several of the more popular school science textbooks. (E)Science on a Shoestring, Herb Strongin (Addison-Wesley Publishing Company, Reading, Massachusetts, 1985, 1976). This book contains nearly 50 elementary science experiments covering several areas of science, including physics. The range of grade levels for each activity is provided at the heading of each experiment description. Drawings of setups are includes where appropriate, along with many photographs of actively engaged students. An appendix provides a list of materials with their sources, mostly supermarkets or hardware stores; all materials are available from a single source in the form of a kit discussed in the book. (E)Taking Charge: An Introduction to Electricity, Larry E. Schafer (National Science Teachers Association, Washington, DC, 1992). This book includes 14 activities on static electricity and 11 activities on current electricity at the middle school level. Each activity includes some background, an objective, suggested activities and/or challenges, and possible additional activities that extend the activity’s study. A Guide for Teachers at the end of the book provides the list of necessary materials and some suggested sources. (E)Safe and Simple Electrical Experiments, Rudolf F. Graf (Dover Publications, Inc., New York, 1964). This book contains 101 simple and safe experiments on the topics of Static Electricity, Magnetism, and Current Electricity and Electromagnetism, written in an informal manner for mainly non-school use. Each experiment includes a list of materials – usually very simple - along with simple instructions and lots of drawings (The title page advertises “164 illustrations.”). This book is particularly nice for groups like scouting dens, cub scout merit badges, or other informal groups where an interest in group intellectual activities is appropriate. At the beginning of the book the author provides “A Brief Chronological History of Great Discoveries in Electricity” between 2637 B.C. and 1895. (E)Flying Tinsel: An Unusual Approach to Teaching Electricity, Grant Mellor (Cuisenaire Company of America, Inc., White Plains, New York, 1993). This book includes 29 experiments, divided roughly equally between three units: Static Electricity, Current Electricity, and Electromagnetism. The book suggests grade levels 5-8, but the development took place with 5th and 6th graders at the school where the author taught. Some of the activities might be challenging to average 5th graders; for example, the author discusses Ohm’s law and solves problems with the aid of the equation. Each experiment is accompanied by a list of materials, an overview, and a brief discussion of necessary teacher background. Other issues are discussed as necessary; many helpful drawings are included where appropriate. A nice glossary is included, and some discussion is presented regarding obtaining materials: some of the materials needed are more sophisticated than those of the average “kitchen physics” book. (E)Simple Physics Experiments With Everyday Materials, Judy Breckenridge, Illustrations by Frances W. Zweifel (Sterling Publishing Co. Inc., 1993). This book, replete with cartoon animals, is written for children in grades 3-6. I thought it rather fun, but some of the explanations are too oversimplified for the editorial reviewer. (E)Electronics for Kids () This material is a class project at the Erie Institute of Technology. It describes twelve experiments with electronics that are safe for elementary school children. Also included are a list of seven additional science experiment reference books and several good science web sites. Take a look. (E) G. Demonstration web sitesThe Physics Instructional Resource Association (PIRA) first met informally at the 1984 Summer Meeting of the AAPT at the University of Maryland. In 1986 the group began meeting formally, and in 1987 adopted the name “Physics Instructional Resource Association.” Since that time PIRA has taken the lead in developing a large number of demonstration based resources for physics teachers, demonstrations technicians, laboratory technicians, and other people interested generally in physics teaching equipment. PIRA also offers a demonstration workshop prior to the yearly AAPT Summer Meeting.Much of the work done by PIRA has been in the area of organizing demonstrations into a universal topical arrangement, called the PIRA Demonstration Classification Scheme (DCS), linked below. The DCS organization includes the major areas of physics, sub-topics of these major areas, individual demonstrations, and demonstration references. This allows interested individuals to communicate quickly with each other and to find information about any specific demonstration or demonstration topic. PIRA has collected this information in an enormous data base of on demonstrations and their use, called the PIRA Demonstration Bibliography, which is also linked below. This compilation identifies about 2,500 basic demonstrations, and includes over 10,500 entries: basic physics demonstrations and variants, listings of the demonstration in each of the important reference manuals identified by the group, and reference papers in various scientific journals. The DCS can be viewed on-line, or can be downloaded from the PIRA Demonstration Bibliography page linked below. Many of the members of PIRA have organized their physics demonstration laboratories around the PIRA DCS numbering system. PIRA has also compiled lists of the 200 and 500 most popular demonstrations, so that any teacher or demonstration technician may be guided in developing new demonstrations that are of the greatest general interest. The PIRA Demonstration Workshop generally features the PIRA 200 demonstrations. The web sites below are associated with the efforts of PIRA and the individual members of that group. or , The PIRA Home Page., The PIRA Demonstration Classification Scheme. , The PIRA 200 Demonstration List., The full PIRA Demonstration Bibliography.Michael Thomason, the Physics Learning Labs Director for the University of Colorado Physics Department and host for the PIRA web site, has provided a Global Demonstration Web Spider that can search more than 60 University Physics Demonstration web sites for information regarding any demonstration using the name, the PIRA number, or key words. This system has become an enormous aid in teaching: finding new demonstrations, looking at alternative explanations for any physics demonstration, surveying photographs and plans for a demonstration that you may wish to duplicate, or finding reference materials that may be helpful for any of the above. , The Global Demo Web Spider. The first University physics demonstration web site was created by Keith Warren at North Carolina State University in early 1995; ten years later there were over seventy-five such sites. The PIRA Global Demonstration Web Spider includes over 60 University physics demonstration web sites, listed at the web site. Below, I have selected a smaller number of these sites, along with a few others, and comment very briefly on the features included on these sites which demonstration devotees or teachers might find of interest. Hopefully this information can be used to aid the development and use of demonstrations as well as to compare demonstration use and availability among peer institutions. Criteria for inclusion in the list below include: (1) photographs and videos of demonstrations that might be useful in understanding and/or duplicating the apparatus, (2) a significant number of original demonstrations, including physics and astronomy, on the site, or (3) other information that may be helpful in the development and use demonstrations, such as finding the most popular demonstrations for use in basic physics courses or information on procurement. The last two entries include lists of University traveling physics demonstration programs; two university museums of antique physics equipment will also be found near the end of the list.

SCIENCE HOBBYIST: Top Page, Bill Beaty. While this web site is not exactly what you would call a university physics demonstration page, it does have information about lots of physics demonstrations as well as a mind-numbing collection of other information, as can be seen by viewing the top page. Through the years I have had a lot of fun and learned a lot of things that helped me in understanding my work better by perusing this web site. The highlights include: demonstration lists, physics toys, physics and electronics projects, a large textbook errors, science fair information and projects, and a collection of other unusual topics. It is worth knowing what is in this site if you are in the business and need good ideas or answers to weird questions from time to time. Nice site! (E) of Vermont Physics Department Antique Demonstrations and Apparatus. This is a very nice pictorial catalog, including a large amount of historical equipment, catalogued by maker, device, topic and date. (I) for Natural Philosophy, Thomas Greenslade, Kenyon College. This is an outstanding collection of historical physics demonstration equipment, collected and organized by Thomas Greenslade, the world expert on antique physics equipment. The site displays pictures, descriptions, documentation, and references for about 1850 pieces of apparatus. This is an incredible treasure, well worth any time taken to browse through the site. (I), The Little Shop of Physics, Brian Jones, Colorado State University. This group has a collection of more than 100 physics demonstrations that are used in several excellent programs aimed at pre-college students and teachers. They hold an annual demonstration open house at the University, and present a variety of demonstration workshops for teachers. (I), Department of Physics, University of Illinois at Urbana-Champaign SCIENCE 2 SCHOOLS. This is the home page of the University of Illinois Physics Van. On the page is a map of the United States with indicators linked to all of the known traveling physics programs in the states. Click on the geographical indicator or on the state to get contact information for the program in which you are interested. The site seems up-to-date. According to the director, Mats Selen, anyone who wants to have something added to the map can email physvan@illinois.edu. Very nice site! (E), American Physical Society: Physics on the Road Programs. This is the formal listing of 22 traveling physics programs known to the American Physical Society. This is not a complete list, compared with the UIUC list above, so people interested in advertisement for their physics road shows should contact the webmaster and send in their information. (E)Demonstration videos, The Video Encyclopedia of Physics Demonstrations, John A. Davis, Brett Carroll, Richard E. Berg, and Jearl Walker, Spanish translations by Adelaida Lopez-Mejia, Josip Slisko, and Raul A. Brito Orta (The Education Group, Inc., 2011) This is a professionally produced set of 600 physics demonstrations, covering all areas of physics. Accompanying written literature discusses the demonstrations in some depth, provides reference material, and gives further information regarding their use. These videos are very appropriate for use in high schools and college/university basic physics courses, especially where demonstrations are not readily available. The Education Group has made many of these films available to students and faculty at certain schools and universities by a special licensing agreement; talk with the company representative to see if your school can make such an arrangement. A full set of 25 DVDs with both English and Spanish narrative is now available from The Education Group; other language narratives are being prepared. (E), Physics Curriculum & Instruction, Physics DVD Titles. Twenty videos of approximately 30 minute length are available, covering the following areas of physics: mechanics (6 films), heat (3 films), sound and waves (3 films), light (2 films), electricity and magnetism (3 films), space flight (3 films) and high-speed photography (1 film). Each individual film includes about eight of the popular physics demonstrations. These films are very professionally done. (E) , Wonders of Physics, Julien Clinton Sprott (University of Wisconsin, 1986-2010). The Wonders of Physics is the title given to the yearly series of public demonstration lectures that Professor Sprott had presented at the University of Wisconsin since 1986. All 27 of these lectures have been videotaped, and are available from the University of Wisconsin in DVD format. Two additional DVDs, with individual demonstration segments for about 85 of the demonstrations which Professor Sprott discusses in his book, Physics Demonstrations: A Sourcebook for Teachers of Physics, are available with the book. Professor Sprott is a highly respected researcher and outstanding teacher, and his Wonders of Physics programs are immensely popular. Information regarding the purchase of these materials is found at the above URL. (E), The Kinetic Karnival Of Jearl Walker, Jearl Walker (WVIZ/PBS Ideastream?, Cleveland, Ohio, 2011). This is a set of six 30-minute videos created by Professor Walker in the 1970s. Titles include: 1. Forces and Collisions, 2. Rotation, 3. Fluid Flow and Friction, 4. Viscosity, 5. The Leidenfrost Effect, and 6. The Science of Cooking. They are all very creatively done, with nice short explanations of the phenomena demonstrated. Video orders can be placed with the WVIZ/PBS Ideastream? Idea Center?: . If you are contemplating doing the “finger in molten lead” or the “walking on red-hot coals” demonstrations, you should probably watch the video entitled The Leidenfrost Effect. These experiments can be very dangerous; serious injury can occur if something goes wrong, even when you believe that you are doing the demonstrations properly. (E), Steve Spangler’s Science, Steve Spangler (Steve Spangler’s Science, 2011). This web site contains over 300 short videos of physics demonstration experiments as performed by Steve Spangler on his weekly Science Mondays segments on KUSA-TV 9 News in Denver. The production is professional and the explanations are brief. These videos can be nicely used in a number of classroom situations, so are well worth reviewing. (E) Demonstrations in Acoustics, Richard E. Berg and David G. Stork (Physics Department, University of Maryland, 1979, 2004). This is a set of two 2-hour DVDs with over 75 individual demonstrations in 29 titled segments; topics include vibrations, waves, and sound, at the level of an introductory non-major college course; a complete listing with further descriptions will be found on the web site. The material was recorded in 1979, and re-issued in DVD format in 2004. These demonstrations, along with large number of others, are used in the Physics of Sound course at the University of Maryland. (E) , The Physics Video Demonstration Database, Cornell University (Matthias Liepe, 2008-2011). The Database includes about 180 films produced at Cornell as well as a number of films submitted by other institutions. (E,I) University of Wisconsin. About 113 short films (most originally 8mm film loops) have been converted to Quicktime movie format and can be seen on this web site. Many of these films can be purchased in DVD format in the Physics Single-concept Films described below. (E) Wake Forest University Physics Demonstration Videos. This web site includes over 150 short videos of demonstrations covering many topics of the general physics curriculum. (E), Engineering and Physics Video Demonstrations, Dave Hall (Colorado State University, 2011). This site contains a very large number of demonstration videos, along with simulations, covering a large number of physics and engineering topics. These materials are short and to the point, and are of excellent technical quality and carefully designed for clarity, both in the videography and in the physics explanations provided. This is one place that you should always look if you need high-quality short films. A short list of other physics film sources is also given. (E,I,A) Alfred Leitner's Old Physics Stories. This page includes links to five movies, in the areas of low temperature physics (at Michigan State University) and classical optics (at Rensselaer Polytechnic Institute), produced by Professor Alfred Leitner. As an MSU physics graduate student in the 1960s, my laboratory was across the hall from Professor Leitner’s production studio, and I found his experiments and videos on superconductivity and superfluid He3 to be immensely interesting and insightful. At this site you will be able to view and download any of the five excellent movies that Professor Leitner has produced. (I), Physics Movies [mpg’s], Robert Barrett, Messiah College. This web page contains short film loops on wave motion produced by Professor Barrett in the 1960s era, as well as some films that he produced in later years. I have used several of these in teaching elementary physics as well as sound and light courses for non-physics students, and found them very helpful. You may download the films from this site. (E)The six DVD set shown below was originally compiled in videodisc format as a project of the American Association of Physics Teachers to collect a number of classic physics 8mm film loops and 16mm films into a single set using DVD format (originally videodisc format), to make them more accessible to physics teachers, most specifically for middle schools and high schools; the commercial advertising material suggests that they are for grade 7 and above. The original films contain a large number of interesting and very well done demonstrations and laboratory experiments, the best of which were excised from the original films, given new narrations, and included with slides and other materials in the final DVD product. The original videodisc set came with a printed “Directory with Bar Codes,” a very detailed descriptive manual that could be used to find any particular video segment of interest and have the videodisc player go immediately to that segment when the bar code is scanned (if you have one of the players with the bar code feature). It appears that the first (Part A and Part B) and third (Part E and Part F) of the videodiscs are still available at this time, but all six of the Parts (A through F) are available in the DVD format. Each DVD comes with a CD-ROM manual containing lesson plans, activities, and reference materials. I prefer the original, complete movies, over these segments, and appreciate the comments given by the original scientists who appeared in the movies. Although some of the material is potentially useful at lower levels, I find the sum product a bit disappointing for use in the college/university setting. My hope is that more of these classic films will be converted to DVD and re-issued in the original version, even though they may seem “quaint” by today’s standards.Physics: Cinema Classics A: Mechanics (I), (American Association of Physics Teachers, College Park, Maryland) (E)Physics: Cinema Classics B: Mechanics (II) & Heat, (American Association of Physics Teachers, College Park, Maryland) (E)Physics: Cinema Classics C: Waves (I), (American Association of Physics Teachers, College Park, Maryland) (E)Physics: Cinema Classics D: Waves (II) & Electricity and Magnetism, (American Association of Physics Teachers, College Park, Maryland) (E)Physics: Cinema Classics E: Conservation Laws, (American Association of Physics Teachers, College Park, Maryland) (E)Physics: Cinema Classics F: Angular Momentum and Modern Physics, (American Association of Physics Teachers, College Park, Maryland) (E)The three sets of physics single-concept films below, most of which were originally published in the 1960s and 1970s as silent 8mm film loops, have been converted to DVD format and a soundtrack added. A Teacher’s Guide is also provided, with information that was originally printed on the boxes that held the film loops. Over my 40-plus years of University teaching, I have found many of these loops to be both convenient and helpful, and am very happy to see them re-issued in this more convenient and modern format. Physics Single-concept Films: Collection 1, Robert G. Fuller, Editor (AAPT Instructional Materials Center, 1993). This set includes Unit 1: Motion (9 loops), Unit II: Motion in the Heavens and Modern Physics (7 loops), Unit III: Momentum and Energy and Waves (10 loops), and Unit IV: Collisions (9 loops). These films were originally produced in 1968 by the National Film Board of Canada with U.S. National Science Foundation Support. (E)Physics Single-concept Films: Collection 2, Robert G. Fuller, Editor (AAPT Instructional Materials Center, 1993). This set includes Unit I: Mechanics (12 loops), Unit II: Collisions and Periodic Motion (10 loops), Unit III: Behavior of Gases (8 loops), and Unit IV: Light and Electricity and Magnetism (8 loops). These films were originally produced commercially and known as Ealing film loops. (E)Physics Single-concept Films: The Miller Collection, Robert G. Fuller, Editor (AAPT Instructional Materials Center, 1993). This set includes Unit I: Mechanics (7 loops), Unit II: Waves (7 loops), and Unit III: Molecular, Atomic, and Nuclear Physics (7 loops). These films were originally included in a series produced by Franklin Miller, Jr. of Kenyon College, Gambier, Ohio, at the Ohio State University with a grant from the National Science Foundation. (E)Twin Views of the Tacoma Narrows Bridge Collapse, This DVD provides two video segments documenting the collapse of the Tacoma Narrows Bridge: (1) the 3’20” segment from the original Tacoma Narrows Bridge Collapse silent 8mm film loop by Franklin Miller, and (2) the 7’40” segment taken from the videodisc The Puzzle of the Tacoma Narrows Bridge Collapse by Fuller, Zollman, and Campbell, that includes an audio track with comments by one of the bridge engineers and a reporter for the local paper who lost his dog and his car in the carnage. (The original interactive videodisc included this video and a lesson on how the collapse occurred. However, the explanation presented is incorrect, so I would not suggest using the videodisc even if it were still available.) These are both very riveting videos, and, in combination with the User’s Guide containing background information, make an excellent product. (E)Frames of Reference, J.N. Patterson Hume and Donald Glenn Ivey (PSSC Physics Films, 1960). This classic film has been converted to DVD format, and is now available from the AAPT with a Barcode and Chapter Guide for use with pre-college students. Although the original black-and-white video is dated, and might be viewed as “quaint” by today’s standards, it is a thoroughly captivating experience to see and hear the two original experts present really interesting material in their unique way. Viewing this movie is an excellent use of 28 minutes of a physics class. (E)Frames of Reference, J.N. Patterson Hume and Donald Glenn Ivey (PSSC Physics Films, 1960, distributed in videodisc format by Central Scientific Company, Franklin Park, Illinois, Copyright EDC, Inc., 1960). This is the videodisc format that is still available from CENCO. (E)Photons/Interference of Photons, John G. King (PSSC Physics Films, 1959, distributed in videodisc format by Central Scientific Company, Franklin Park, Illinois, Copyright EDC, Inc., 1959). These two films form a nice set, narrated by the original researcher. It is instructional to see how Professor king describes his apparatus and explains the physics involved. I have found it helpful to combine this video with the actual demonstration in classes on quantum physics. (E,I)Charles and Ray Eames: Pioneers of Visual Ideas, Visual Pathfinders, Catalog #31537 (Ray Eames and Laserdisc Corporation of America, 1988). This videodisc includes the original “Powers of Ten” video, with its outstanding narration by Philip Morrison, which I strongly prefer over the version published later with a different narrator. Another video on this disc is “Tops,” showing a number of tops of indigenous American people; I showed this one as people came into the lecture hall for our public Physics is Phun program on rotational physics, “Going in Circles with Physics.” I have not found a current source for the materials on this videodisc, but hope that they will be re-issued. Note that “Powers of Ten” can also be found in several versions on YouTube. (E) , University of Maryland, Physics Lecture-Demonstration Facility, AUDIO-VISUAL LIST. Beginning in the 1960s, the University of Maryland Physics lecture-Demonstration Facility collected a very large number of physics films from a variety of sources. This web page lists these films by physics topic, and includes over 600 titles. We obtained these films from a variety of sources, including purchase and the now defunct Commission on College Physics. It is included solely to provide information on the breadth of physics films that have been produced over the last fifty years. (E)Physics computer simulationsAn enormous number of physics simulations have been developed during recent years, many of which are readily available on both University and commercial web sites. The earliest programs were written for the Apple Macintosh in JAVA language, and were called “Applets.” At this point, simulations are readily found in JAVA, Shock, and Flash (“Flashlets”). Professor Wolfgang Christian holds the copyright on the term “Physlet?,” so the copyright symbol should be attached to that term. Terms such as simulation, animation, Applet, and model, as well as Physlet? apply to these programs. This document provides links to information on the web and in books based on two primary criteria: (1) a significant number of quality simulations are available from the source, and (2) these simulations must for the most part be original, not simply a listing of those written by another source.Physlet Physics: Interactive Illustrations, Explorations and Problems for Introductory Physics, Wolfgang Christian and Mario Belloni (Addison-Wesley, Reading, Massachusetts, 2004). This CD-ROM contains over 800 Physlet? exercises. (E)Physlet?

These labs are designed to accompany the Kinetic Books physics texts, and are written at three levels: Conceptual Physics, Principles of Physics (Physics AP/B exam level), and Physics for Scientists and Engineers (Physics AP/C exam level). They have a very informative web site: that describes both their electronic textbooks and their virtual physics laboratories, and allows visitors to surf through some of the lessons and labs. They claim that their materials are good for use in high schools and colleges as well as home schooling, and on their web site have included a list of over 100 colleges and universities that have purchased their products, including a few non-American English speaking schools. This book is currently available from the AAPT. (E), Physlets?: The Physlets resource page, with links to important pages and references (Wolfgang Christian, Davidson College, 2005-present).

(I,A), Physics by Demonstrations, (Oracle ThinkQuest, 1999). “Projects by students for students.” Set of 21 simulations covering most major topics in physics. (E)Physics Education Research involving demonstrations and simulationsBeginning by about 1980, serious study was initiated in the area to be known later as “Physics Education Research.” Initially, the results of this research were published in The Physics Teacher and The American Journal of Physics; in 1999 the AJP began to issue supplements for Physics Education Research once or twice a year. In 2005 this research area was formally recognized by the American Physical Society, with its own journal: Physical Review Special Topics - Physics Education Research has been published twice yearly since that time. One of the sub-topics included in this endeavor is the use of demonstrations in physics teaching. Investigations have included whether demonstrations actually have any value in teaching, or are more of a distraction, a confusing influence or simply entertainment. Quantitative and qualitative techniques for the teaching and the evaluation of learning using demonstrations have been developed, and using these techniques studies have been carried out regarding the best techniques for use of demonstrations in the classroom and lecture hall. “Resource Letter: PER-1: Physics Education Research,” Lillian C. McDermott and Edward F. Redish, Am. J. Phys. 67, 755-767 (1999). This is an outstanding, and very complete, bibliography of materials from the earlier period of Physics Education Research, including earlier bibliographical reference materials and well documented conference proceedings. One of the important topics of then current research regards the effectiveness of demonstrations in teaching physics; a large section of the document is subdivided into detailed studies in learning in the various topics of general physics, with smaller sections detailing the state of other significant aspects of student learning, such as learning of concepts and how to apply mathematics to physics. (A)Peer Instruction: A User’s Manual, Eric Mazur (Prentice Hall, Upper Saddle River, NJ, 1997). Professor Mazur has pioneered the concept of Peer Instruction (PI), often using a demonstration as the centerpiece of a discussion regarding the physics topic under study. In PI using demonstrations, students are given the opportunity to vote as to the outcome of a demonstration experiment before the experiment is carried out, then given the opportunity to further discuss the outcome after seeing the demonstration. This provides the student with some additional motivation in learning the subject matter as well as the opportunity to learn from each other. This book provides help with the procedure as well as a large number of questions and demonstrations. (A)Review of “Peer Instruction: A User’s Manual,” Mark D. Sommers, Am. J. Phys. 67, 359-360 (1999).

Gavrin, and Wolfgang Christian (Prentice-Hall, Upper Saddle River, NJ 07458, 1999). From the cover material: “[JiTT] is an exciting new teaching and learning methodology designed to engage students by using feedback from pre-class web assignments to adjust classroom lessons so that students receive rapid response to the specific questions and problems they are having.” The book includes some philosophy, strategies for implementation of this procedure, and lots of questions for use in most physics topics. The book should be very helpful to any teacher implementing JiTT, and even for general ideas regarding concept tests. (A)“Peer Instruction: Ten years of experience and results,” Catherine H. Crouch and Eric Mazur, Am. J. Phys. 69, 970-977 (2001). From the abstract: “We report data from ten years of teaching with Peer Instruction ~PI! in the calculus- and algebra-based introductory physics courses for nonmajors; our results indicate increased student mastery of both conceptual reasoning and quantitative problem solving upon implementing PI. We also discuss ways we have improved our implementation of PI since introducing it in 1991. Most notably, we have replaced in-class reading quizzes with pre-class written responses to the reading, introduced a research-based mechanics textbook for portions of the course, and incorporated cooperative learning into the discussion sections as well as the lectures. These improvements are intended to help students learn more from pre-class reading and to increase student engagement in the discussion sections, and are accompanied by further increases in student understanding.” (A) “Peer Instruction: Engaging students one-on-one, all at once,” Catherine Crouch, Jessica Watkins, Adam Fagen and Eric Mazur, in Reviews in Physics Education Research, edited by E.F. Redish and P. Cooney (American Association of Physics Teachers, College Park, MD, 2007). From the abstract: “We describe Peer Instruction (hereafter PI) and report data from more than ten years of teaching with PI in the calculus- and algebra-based introductory physics courses for non-majors at Harvard University, where this method was developed. Our results indicate increased student mastery of both conceptual reasoning and quantitative problem solving upon implementing PI. Gains in student understanding are greatest when the PI questioning strategy is accompanied by other strategies that increase student engagement, so that every element of the course serves to involve students actively.” Experiences at several universities are included. (A)“Using JiTT with Peer Instruction,” Jessica Watkins and Eric Mazur, in Just in Time Teaching Across the Disciplines, edited by Scott Simkins and Mark Maier, pp. 39-62 (Stylus Publishing, Sterling, VA, 2009). From the abstract: “Separately, both JiTT and PI provide students with valuable feedback on their learning at different times in the process -- JiTT works asynchronously out of class, and PI gives real-time feedback. Together, these methods help students and instructors monitor learning as it happens, strengthening the benefits of this feedback.” (A)“Peer Instruction: From Harvard to Community Colleges,” Nathaniel Lasry, Eric Mazur and Jessica Watkins, Am. J. Phys. 76, 1066-1069 (2008). From the abstract: “…not previously reported are the following two findings: First, although students with more background knowledge benefit most from either type of instruction, PI students with less background knowledge gain as much as students with more background knowledge in traditional instruction. Second, PI methodology is found to decrease student attrition in introductory physics courses at both four-year and two-year institutions.” (A)“Peer Instruction: Results from a Range of Classrooms,” Adam P. Fagan, Catherine H. Crouch, and Eric Mazur, Phys. Teach. 40, 206-209 (2002). Summarizes results from PI use in University, four-year college, two-year college, and high school.

Response times under various circumstances, helpful in design of a curriculum using these questions. (A), The Physics Suite, Karen Cummings, Priscilla Laws, Edward F. Redish, Patrick Cooney, David Sokoloff, Ronald Thornton. From the web summary of the Suite: “Based upon Halliday, Resnick, and Walker’s FUNDAMENTALS OF PHYSICS 6e, this narrative text is designed to work with interactive learning strategies that are increasingly being used in physics instruction (for example, microcomputer-based labs, interactive lectures, etc.). In doing so, it incorporates new approaches based upon Physics Education Research (PER), aligns with courses that use computer-based laboratory tools, and promotes Activity Based Physics in lectures, labs, and recitations.” The Physics Suite includes a number of individual books, including the next two entries in this list. See the link for detailed description. , Teaching Physics With the Physics Suite, Edward F. Redish. As part of The Physics Suite, this wide-ranging book includes philosophy, practical advice, and lots of information about physics, physics learning, and physics education research, and contains an enormous bibliography of literature based on sound physics education research. It is certain to be helpful not only if you use the Physics Suite, but also in virtually any physics teaching endeavor. The link leads to a late version of the book before publication. (A)Interactive Lecture Demonstrations, Active Learning in Introductory Physics, D. R. Sokoloff and R. K. Thornton (John Wiley & Sons, Hoboken, New Jersey, 2004). This book, part of the Physics Suite, contains a large number of interactive lecture demonstrations, that is, questions based on the use of classroom demonstrations which are presented to the class during the discussion of the experiment, usually by way of prediction of the outcome of the demonstration. Graphs are used in lieu of complex calculations; many of the demonstrations involve plotting graphs obtained using probes available from Vernier or Pasco, so the student is familiarized with equipment that can also be used in the lab. Demonstrations, organized by topic, cover most areas of the general physics curriculum. This book contains a number of excellent ideas, and is well worth obtaining. (E) The Physics Question of the Week, Richard E. Berg (Physics Department, University of Maryland, 2001-2010). The Physics Question of the Week includes 365 physics “brainteaser” type questions in the form of demonstrations, which are asked and answered in the form of quick and relatively simple experiments, many of which are presented in video format. These are very useful as interactive demonstrations using the Peer Instruction technique. A topical list is linked at the beginning of the QOTW home page.

Holcomb, and Rosanne Di Stefano, Phys. Today 64, 32-37 (1993). The Introductory University Physics Project (IUPP) was a major study of the calculus-based introductory physics courses at nine major American University physics departments. The goal of the study was to evaluate four new curriculum models that were developed for the project. This paper lays out the goals and the techniques used in implementing the research. Some of the preliminary results are presented in the next paper in this list. (A)“The IUPP evaluation: What we were trying to learn and how we were trying to learn it,” R. Di Stefano, Am. J.

Hake, Proceedings of the UNESCO-ASPEN Workshop on Active Learning in Physics, University of Peradeniya, Sri Lanka, 2-4 December 2002. This paper discusses methods to assess the effectiveness of use of demonstrations on student learning of physics concepts, and suggests a general procedure. It should be noted that a variety of techniques have been used in this type of evaluation and there remains a large amount of controversy regarding the effectiveness of demonstrations as opposed to computer simulations, so this topic is significant. Almost 100 references are listed in the test, with direct links to on-line PDF versions of many papers. (A) “Classroom Demonstrations: Learning Tools or Entertainment?,” Catherine H. Crouch, Adam P.

From the abstract: “This paper reports on learning gains for two different Projects over ten years. In Project 1, the ILDs were implemented from 1999 to 2001 with students who had successfully completed senior high school physics. The learning gains for students not exposed to the ILDs were in the range 13% to 16% while those for students exposed to the ILDs was 31% to 50%. In Project 2, the ILDs were implemented from 2007 to 2009 with students who had not studied senior high school physics. Since the use of ILDs in Project 1 had produced positive results, ethical considerations dictated that all students be exposed to ILDs. The learning gains were from 28% to 42%. On the one hand it is pleasing to note that there is an increase in learning gains, yet on the other, we note that the gains are nowhere near the claimed 80%.” (A)“Teaching Physics: Figuring Out What Works,” E.

There was no statistically significant difference between the pre and post data of the students in the two groups. Students who performed the virtual experiment were able to answer questions dealing with work and potential energy more correctly, though neither group was able to offer sound reasoning to support their answers.” (A) “The impact of a science demonstration on children's understandings of air pressure,” Daniel P. Shepardson, Elizabeth B. Moje, Amy M. Kennard-McClelland, Journal of Research in Science Teaching 31, 243–258, March 1994. This paper is available for purchase on line from the Wiley On-Line Library. From the published abstract: “Constructivist theory guided our investigation of the impact of a scientific demonstration on children's understandings of air pressure. Primary data sources included children's written and oral interview responses. For one-third of the children, the demonstration reinforced previous understandings. These children appeared to utilize their prior knowledge and experiences to construct the purpose and meaning of the demonstration. Therefore, these children's understandings were not sufficiently challenged by observing the demonstration or the social interactions that occurred. Recommendations for using demonstrations to promote children's scientific understandings are presented herein.” (A), “Toward a modeling theory of physics instruction,” David Hestenes, Am. J. Phys. 55, 440-454 (1987). This paper provides one basis for much of the contemporary effort to reform physics teaching, along with other efforts and publications by the author. It describes much of the content of the Modeling Instruction Program at Arizona State University. (A), Modeling Instruction Program Research, David Hestenes. This very informative web site presents information with links to articles regarding research into the modeling theory as well as links to discussions regarding the Force Concept Inventory, both supportive and critical. (A)One of the important discussions that have taken place in the Physics Education Research community has been over the issue of how to evaluate the effectiveness of the testing procedures. One such tool is the Force Concept Inventory, a multiple-choice test that has been used for a number of years to evaluate students’ understanding of Newton’s laws. The following set of papers provides some background regarding the discussion of this issue., “Force Concept Inventory,” David Hestenes, Malcolm Wells, and Gregg Swackhamer, Phys. Teach. 30, 141-158 (1992). An early article describing research supporting the Force Concept Inventory. (A) “What does the Force Concept Inventory Actually Measure?,” Douglas Huffman and Patricia Heller, Phys. Teach. 33, 138-143 (1995). This article suggests that analysis of the Force Concept Inventory may be more complicated than Hestenes, Wells, and Swackhamer suggest. (A), “Interpreting the Force Concept Inventory: A response to Huffman and Heller,: David Hestenes and Ibrahim Halloun, Phys. Teach. 33, 502 (1995). Hestenes and Halloun take issue with the criticism of Huffman and Heller. (A), “Interpreting the Force Concept Inventory: A Reply to Hestenes and Halloun,” Patricia Heller and Douglas Huffman, Phys. Teach. 33, 503-511 (1995). This is the answer by Huffman and Heller to the responses by Hestenes and Halloun to the original Huffman and Heller article above. (A), “Beyond problem solving: Evaluating introductory physics courses through the hidden curriculum,” UMD PERG PhD Dissertation: Jeffery M. Saul (1998). Chapter 4 of the thesis, Multiple Choice Concept Tests: The Force Concept Inventory (FCI) presents an analysis of the arguments regarding the concerns about the Force Concept Inventory. (A), “Common Concerns About the Force Concept Inventory,” Charles Henderson, Phys. Teach. 40, 542-547 (2002). Discusses some of the issues that remained after almost ten years of use of the Force Concept Inventory. (A), fci force concept inventory, contains a number of links to FCI related publications, as well as a link to the actual FCI questions and answers. A physics teacher can obtain these files, but must first be identified as legitimate. (A)A provocative teaching technique is to purposefully create incorrect models or simulations and ask students to find the errors, either through the physics or the programming. The following examples illustrate this technique.“Teaching Physics (and Some Computation) Using Intentionally Incorrect Simulations,” Anne J. Cox, William F. Junkin, III, Wolfgang Christian, Mario Belloni, and Francisco Esquembre, Phys. Teach. 49, 273-276 (2011). From the abstract: “[W]e have developed a series of simulations that are intentionally incorrect, where the task is for students to find and correct the errors.” These simulations deal with electric fields. (A), Electric Field: What is Wrong? Package, Anne Cox, Wolfgang Christian, and Francisco Esquembre. (The Open Source Physics Project is supported by NSF DUE-0442581). , Question of the Week # 2: Racing Balls, Richard E. Berg, University of Maryland Physics Lecture-Demonstration Facility. This link has been inserted here to call attention to one of the most interesting of the interactive demonstrations. Among groups of high school students, university students, physics majors, physics graduate students, and physics professors, the percentages who guess the correct result for the outcome of this experiment is about the same, with the predictions approximately well distributed among the possible outcomes. See the next entry. (E,I,A) , Two-tracks animations, from Tom Thaden Koch, Ph. D. thesis: “A Coordination Class Analysis of College Students' Judgments about Animated Motion.” For this project, students reviewed computer animations that show (by purposefully using incorrect programming) each of the three possible solutions to the racing balls problem, and the results, along with the logic obtained from interviews with the students, are discussed. From the animations, any of the three possible solutions may seem reasonable even to many experienced physicists!! (Follow the series of links from the link “animations” to the end to see the two-track, flat track animations.) This is a clear illustration of issues that can arise with use of computer modeling in lieu of actual demonstrations. (A)AcknowledgmentsI give special thanks to PIRA and to several of the individual members who were very helpful in providing information important to this document, as well as Professor Joe Redish (University of Maryland) for his insightful comments regarding physics education research. I also thank the reviewers, particularly Wolfgang Rueckner (Harvard University) and Dale Stille (University of Iowa) for their helpful suggestions. Most importantly, I thank Keith Warren (North Carolina State University) and Brad Shue (now at the University of Cincinnati) for a very thoughtful and detailed conversation at the 1995 AAPT Summer Meeting, during which they told me about the new interconnection of computers known as the World Wide Web, and how it could be used to propagate pictures and information about physics demonstrations. This discussion inspired me to create the physics demonstration web site at the University of Maryland in 1996. ................
