AP CHEMISTRY SYLLABUS
A. INTRODUCTION
1. This course meets 15, forty-three minute periods every two weeks with eleventh
and twelfth graders.
2. Students are expected to spend one to two hours per night on homework and
studying.
3. Students receive one credit with the grades weighted as follows: A-5, B-4, C-3,
D-1, F-0.
4. The following grading scale is used:
A 100%-92%
B 91%-83%
C 82%-72%
D 71%-61%
F 60%-0%
5. The grades are determined by total points on tests, problem sets and lab reports.
6. The textbook used is Chemistry, 8th edition, by Whitten, Davis, Peck, and Stanley,
Thomson Brooks/Cole Publishing, 2007.
7. The main laboratory manual is Laboratory Experiments for Advanced Placement
Chemistry, 2nd edition, by Sally Ann Vanderbrink, Ph.D., Flinn Scientific, Inc.,
2006.
a. Most of the 26 experiments in this manual are used.
b. Experiments from other manuals are also used as I feel are necessary.
c. Students also do a number of computer generated experiments from the
Pasco set of experiments.
8. An average of two periods out of eight each week are spent by the student on
laboratory experiments. In addition, numerous teacher demonstrations are shown
throughout the year, particularly as an introduction to each unit. Students work in
groups of two in the laboratory. Approximately, fifteen lab reports are submitted
by each student during the year with some reports including two or more related
labs together. Students are encouraged to share their thoughts on the laboratory
experiment during pre and post lab discussions, but are to do their own individual
lab reports. A portfolio of individual lab reports will then be kept by each student
after the reports are graded. The laboratory report includes the following: Title,
Purpose, Theory, Procedure, Data, Graphs, Calculations, Conclusion.
9. Problem Sets for each unit have been set up. These are completed by the students
for every unit, and consist of released Multiple Choice Questions and Free
Response Questions over the last ten years.
10. Before the AP Exam in the spring, I spend five, two hour evening sessions and
one double period day session reviewing with the students taking the test. We
review the problem sets to each unit. Afterwards, the students are given a sample
AP Chemistry Exam, and then we discuss any questions they have.
