"A mind, once stretched, can never return to its old dimensions"CP Chemistry Voorhees, 2017-2018Room 317Course Objectives:to apply scientific methods of inquiry, math, computer tools, and interdisciplinary connections in your study of chemistryto gain an in-depth knowledge of basic chemical and physical principles to become experienced with standard safety and operating procedures in a chemical laboratoryto develop interpersonal, study, writing, and presentation skillsText:Chemistry (? 2002) by Addison-Wesley.Materials:3-ring binder (1 inch-for chemistry only), 3-hole punch paper, dividers or folders, blue or black pens, pencilsCalculator (must have log and exponent, graphing a plus)Activated account on school computer network Assignments/You are responsible for what is covered in class. To succeed, you must Homework: come to class prepared and keep up with the assigned readings, homework, special assignments, and labs. (Don’t procrastinate in getting help if you need it.)I will check for the completion of homework at the beginning of class and may occasionally collect it. Homework will account for approximately 10% of your grade.All assignments are to be submitted on the specified due dates. If you are absent the day the assignment is due, it is to be turned in the day you return. No assignments will be accepted after the indicated due date except for legitimate reasons. You are responsible for knowing your assignments and their due dates.Tests/Quizzes:Tests and quizzes will be based on notes, reading, labs and classroom discussions. Tests are always announced in advanced, quizzes may not be. Be prepared to take a test the day it is scheduled, even if you were absent any day before. If you are absent the day of a test you must take it the day you return. (Exceptions will be made for extended absences). Make-up tests are generally more challenging. You are responsible for scheduling a make-up for a test with the teacher. In general, a make-up test will only be delayed for the same number of days you were absent. Laboratory:Your laboratory grade will be based upon how you conduct yourself in lab, on the written lab reports, and on pre-lab quizzes or assignments. Reports are due at the beginning of a class period. Labs handed in any time after the beginning of class will be considered late. There will be a reduction of the lab grade for each day late.Although data may be shared with a lab partner, the body of the lab is individual work and copying will not be tolerated.Extra Help:I will be available for extra help Monday, Wednesday and Thursday after school. Forming a study group with classmates is helpful. But remember, you are responsible for turning in work that is your own.Grading:An approximate distribution of your grade follows. Some special assignments/projects will be counted as a laboratory or quiz grade. Grades are calculated on a points system and these percentages are approximate.Tests/Quizzes45%Laboratory35%Do Now10%Homework 10%Total-100%Conduct: Arrive to class on time. Visits to the restroom and lockers should take place before the class period is scheduled to begin. If there is an urgent need to leave the classroom, you are required to get permission and sign out. Only one person is allowed to be out of the classroom at any given time.Classroom Rules:My expectations are that we will treat each other with respect and courtesy. Enter the room quietly and be ready to work each day.Avoid language that insults, hurts, or offends others. Remain seated until the bell rings.No cell phones should be visible during instruction.Leave the room neat. This is a shared space as well as our “home” for the year. Keep it clean. Consequences:verbal warningteacher detentionparent phone call immediate removal from the classroom at discretion of the teacheradministrative referralCP Chemistry – Syllabus Text: Chemistry (? 2002) by Addison-Wesley.Unit 1: Introduction to Chemistry and Matter Objectives:Define chemistry and matter.Define observation, hypothesis, experiment, theory, and law in scientific process.Apply the scientific method of investigation.Define energy and distinguish between kinetic and potential energy.Explain the law of conservation of mass-energy.Describe and distinguish between mixtures and pure substances, homogeneous and heterogeneous substances, elements and compounds.Differentiate between physical and chemical properties of matter.Distinguish physical and chemical changes in matter.Explain the relationship between chemical change and energy.Review lab techniques, equipment, and safety.Laboratory/AssignmentsLaboratory Techniques, Equipment, and SafetyCandle observationsEvidence of Interaction-Copper II ChloridePhysical and Chemical ChangeHomeworkUnit 2: The Measurement of Matter and Problem Solving Objectives:List and use the SI base/or derived units for mass, length, volume, time, and temperature.Express and convert quantities using the common SI prefixes.Use the factor-label (dimensional analysis) to obtain the desired unit in solving problems.Use significant figures to express the exactness of measurements.Express any number in scientific notation.Make use of scientific notation in addition, subtraction, multiplication, and pare and contrast the accuracy and precision of a measurement.Determine the densities of different substances.Perform calculations using density measurements.Laboratory/AssignmentsDensity of metalsDensity and Pennies.Coke Density and Accuracy and Precision of Lab Glassware.HomeworkUnit 3: Atomic Theory Objectives:Discuss the Dalton’s atomic theory.Discuss the historical development of the atomic theory and contributions from Thompson, Rutherford, Bohr, and Schrodinger.Identify and describe the three fundamental particles of the atom and how they are arranged in or about the nucleus.Define atomic number and atomic mass and use them to fine the number of protons, neutrons, and electrons in an atom.Describe how atoms of isotopes of an element differ and explain why atomic masses are not whole numbers.Calculate the average atomic mass given the isotope distribution of an element.Recognize general shape of s, p, d, f atomic orbitals.Identify the number of electrons in the outermost energy level.State the importance of a noble gas configuration and explain and use the octet rule.Draw electron-dot diagrams for the elements, monatomic ions, and excited state atoms.Laboratory/AssignmentsFlame TestsGas tubes and spectroscopesHomeworkUnit 4: Periodic Table Objectives:Describe the early attempts at classifying elements.State the Periodic Law.Explain the basis for the arrangement of the modern periodic table.Recognize the organization of the periodic table into s, p, d, and f blocks.Use the periodic table to predict the electron configurations of elements.Identify metals (alkali, alkaline earth, transition, inner transition), nonmetals, metalloids, halogens, and noble gases on the periodic table.Summarize the characteristics for families of elements.
