Ohn-Sabatello, Morlan, and Knoespel, 2006, McDougal Littell. Laboratory: Laboratory experiments are an integral part of the AP Chemistry course. Students will spend an average of the equivalent of a double period per week (including set-up) in laboratory investigations, all of which will be hands-on, wet-labs. Duplicate or triplicate trials are run on most experiments so that precision can be calculated. Students will work in teams of two to conduct lab investigations, but will independently keep a lab notebook and write lab reports. Lab reports will be done in the bound lab notebook and will include Purpose, Procedure, Data Tables, Calculations and/or Graphs, Conclusions, Discussion of Theory, Error Analysis (this also includes calculations of % deviation and % error), and a critique/evaluation section. Students will alternate lab reports between two notebooks so that one lab report can be collected and graded while the next lab is performed. Following each experiment, students will share results and interpretation of those results in class discussions. All College Board Recommended Labs will be covered, with additional labs done in the areas of Thermochemistry and Acid/Bases. In the mornings during the week of OGT testing, AP Chemistry students will conduct the cation/anion qualitative analysis lab Homework: Homework is assigned daily and will typically require about 45 minutes for textbook reading and required calculations. Reading assignments for each topic will include the Zumdahl text (entire chapter) as well as the Zumdahl study guide and related chapters in the Peterson s AP manual and in Fast Track. Required homework problems will include most of the problems from the textbook study guide and selected problems from the textbook end-of-chapter problems. Review before chapter tests will include assignments from Fast Track and from

2 Peterson s AP Chemistry study manual which both include Free Response practice. Daily homework will constitute 10% of the grade each quarter. Lab reports are in addition to this daily homework. Net Ionic Equations: Starting with Chapter 4, different classifications of reactions will be studied and net ionic equations will be practiced and tested throughout the year. Tests/Quizzes: Short quizzes will be given very frequently(2-4 per week). These will usually be multiple-choice, as a combination of calculation-based and conceptual questions. Tests will be given at the conclusion of each chapter and will be extremely rigorous, with a combination of multiple-choice and free-response questions, and net-ionic equations. The questions are at the level of AP exam questions, and each test will include some questions from previous chapters as the year progresses. Independent Study: Chapters 1-3 in Zumdahl were extensively covered in the Honors Introductory Chemistry course and homework from those chapters will be done as review over the summer. A test over Chapters 1 and 2 will be given the 2 nd day of school, and a test over Chapter 3 will be the 2 nd week, after completion of the Gravimetric Analysis lab. Chapter 22, on Organic Chemistry, will be done independently over Winter Break. A test over this chapter will be given the 2 nd day after break. The lab Synthesis, Purification and Analysis of an Ester will be conducted the final week of regular classes, after the AP Chemistry exam. Chapter 18, on Nuclear Chemistry, was extensively covered in Honors Introductory Chemistry, and will be done as an independent assignment over Spring Break, with a test given the 2 nd day after break. AP Exam Review: The last 3-4 weeks before the AP exam will be review. Students will do old AP exams and practice exams as homework, with a multiple-choice section done one night, and the free-response section the next night. A set of net ionic equations will be done every day. Additional equilibrium problems will be done on the weekends. Students are encouraged to come in before and after school to work in study groups and also to form study groups outside of school.
