AP Chemistry ClassDr. Steve W. AltstielTentative Class Syllabus AP Chemistry (2015-16)COURSE DESCRIPTIONStudents develop the ability to use scientific skills and processes to explain the composition and interactions of matter. Students use mathematics to predict and analyze the outcomes of chemical reactions and the interactions of matter and energy. Science skills and processes learned in this course build on those developed in biology and prepare students for continued development of scientific inquiry in other science disciplines. Topics of study include: structure of matter, states of matter, chemical reactions, and descriptive chemistry. Laboratory work is an integral component of this course. The completion of General Chemistry and Algebra I are prerequisites.COURSE OUTLINEFirst SemesterUnitReview of 1st Year ConceptsElectronic Structure of AtomsPeriodic Properties of ElementsChemistry of NonmetalsBasic Concepts of Chemical BondingMolecular Geometry and Boding TheoriesGasesLiquids and Intermolecular ForcesSolids and Modern MaterialsProperties of SolutionsReactions in Aqueous SolutionsChemical KineticsThermochemistrySecond SemesterUnitChemical ThermodynamicsChemical EquilibriumIntroduction to Organic ChemistryAcid-Base EquilibriaAdditional Aspects of Aqueous EquilibriaElectrochemistryPreparation for AP Exam?REQUIRED TEXTBOOK AND MATERIALSBrown, T. L., LeMay, H. E., Bursten, B. E., Murphy, C. J., & Woodward, P. M. (2012). Chemistry, the central science (12th ed., AP ed.). New Jersey: Pearson Prentice Hall.Hill, J. C. (2012). Student guide (12th ed.). New Jersey: Pearson Prentice Hall.Waterman, E. L. (2014). Test prep series for AP chemistry: To accompany chemistry, the central science (12th ed., AP ed.). New Jersey: Pearson Prentice Hall.Student supplied materials:a. Loose leaf paper and notebook?b. Pencils (for math problems/equations) and pens (blue or black only)c. Graphing calculator (TI-83/84 or TI-83/84 Plus)CLASSROOM PROCEDURESHomework Policy: Students have up to 3 days grace period to turn in a late assignment for 75% credit.? No homework will be accepted after that date unless arrangements have been made with the instructor prior to the expiration of the grace period.? Students who turn in their assignment by the due date and earn a C or less on the assignment are allowed to redo their assignment for a higher score, but the redo must be turned in before the end of the three day grace period. Students must show all work for assignments requiring calculations.Examination Policy: Students that earn a C or less on any exam are allowed to take a “redo” test at home.? They are allowed to use any resources to work on the test, however it must be returned no later than 3pm the following school day.? Upon grading the redo test, the student is eligible to earn back ? of the points they missed as long as their score warrants that addition.? For example, if a student scores 75 pts. out of 100 on an exam, they can earn back 12.5 of the 25 points they missed in order to score an 87.5; however if they only earn an 84 on the makeup exam, then their final score will be an 84.Makeup Work Policy: Makeup of missed labs will be scheduled to accommodate as many students as possible at one time.? Tests are to be made up as soon as possible. If a test is not made up within a one week (seven day) grace period, a “MSG” (missing) will be placed in GradeSpeed, which registers as a zero.Tardiness:? Students are required to be in their seats and ready to work before the tardy bell rings. If a student is not grossly tardy (>5 minutes late), does not disrupt the class upon entering and immediately starts working upon arrival; the student will be marked tardy, but I will not deduct points for their tardiness.? However, habitual tardiness (>5 tardies per semester) will result in point deductions, referrals to and follow-up with parents.Preparation:? Students must bring all required materials (text book, calculator, pen/pencil, homework and paper) to class each class period and be ready to work.Lab Exercises:? Safety is supreme.? Students will wear an apron and goggles when directed.? Open toed shoes are not allowed on lab days. Ladies and gentlemen with long hair must pull back and tie their hair.End of class:? Class is dismissed by the instructor - NOT by the bell.Help outside class:? Help is available after school Sunday through Wednesday if needed, except for afternoons with faculty meeting commitments.GRADING CRITERIAComponentPercentageAttendance/Participation10%Homework/Classwork**25%Lab Reports25%Exams/Projects40%?** If a student is absent on the day classwork is collected and graded, the student will either be exempted from the classwork with no penalty, or required to make up the work within the three day grace period.LETTER GRADESA+100%C76%A96%C-72%A-92%D+69%B+89%D66%B86%D-62%B-82%F59%C+79%Contact at:? ?steve.altstiel@eu.dodea.edu AP ExamAll students enrolled in this course will take the AP Chemistry Exam. The AP Chemistry Exam will occur on May 2, 2016 at 8:00 AM.Lab Report ExpectationsEach lab report should be concise (no more than 1-3 pages of text; data, graphs and calculations may make the entire document longer) and have all of the following sections:AbstractThe abstract should be a short summary of the experiment and the conclusions.? A good abstract should have the following information:Description of experimental purpose.Description of the experimental method.Short summary of the results.IntroductionThe introduction is where the theory and the purpose of the experiment are discussed.The theory of the experiment is a discussion of the chemistry behind the experimental method.? For example, if the lab is an acid-base titration, a short discussion of how titrations work, how the results are generated, what indicators are used, etc.The purpose section of the report is to tell the reader “what are we trying to learn by doing this experiment?”? For example, in a titration, we may be trying to determine the concentration of an acid, or the pKa of a substance.?The above listed parts should tie together to explain how the chosen method will answer the questions that we are trying to determine.Methods and MaterialsDetails of the experimental procedure and what chemicals and equipment are used in the experiment.This is not a section for a step-by-step, bulleted procedure.? This is a narrative outlining important steps.?You need to use your discretion to decide what is important; for example, do you need to specifically mention that you washed glassware? ?Should you mention that you found that if you stirred consistently for only 3 minutes, the reaction turned partly cloudy; but if you stirred the reaction for 3 minutes, then chilled the reaction beaker, the reaction became solid precipitate??Decide what is important. ??DataAs expected, this is the section where the data collected is listed and what calculations are needed to determine the results.? In this section, the following information must be included:Raw data collectedCalculations needed to determine the resultsIf there is a single calculation that must be done multiple times, then a single set of the calculations can be shown in order to illustrate the appropriate steps.Charts, graphs or images that are generated.Results/ConclusionThis section should be a summary of the results that were generated, only in summary form instead of chart-based form. ?Some explanation of assumptions that were made should be discussed.There should be a short summary of what can be concluded from the experiment.Did you determine what you were expecting?Did something happen to confuse or negate the results?ReferencesIf in the introduction a textbook or other reference was needed to explain the method, those should be listed.Appropriate references should be provided by indicating a reference point in the text(1) and then a listing in the reference section.? Typically, references are meant to be a short way of providing the source of the information.? The goal is to provide the reader with all of the information necessary for them to find the reference.For example, if the above reference (1) was from the Journal of Biological Chemistry from January 2006, written by John Doe on pages 25-28, the appropriate reference would be cited as follows:Doe, John.??J. Biological Chemistry; (2006); vol 1; Pgs 25-28.Books and other types of reference materials can be sited in other ways, if you have materials to be cited please let me know and I will provide you with the resources to correctly site your materials.Sample AssignmentName ____________________________Period____________________________Date_____________________________1.
