AP Chemistry



AP Chemistry Syllabus/LongRange Plans

DCS 2008-2009 School Year Mr. J Szeryk.

Text

Chemistry by Steven S. Zumdahl, 3rd ed., Heath and Company, 1993.

ISBN: 0-669-32462-0.

Scheduling

Students are expected to be in class on time with the required materials. The AP Chemistry class meets for 85 minutes every second day of the week. Students in AP Chemistry have already taken a first year Chemistry course at Damascus Community School.

On average, one period each week is for laboratories. After the AP exam the class becomes a strictly a laboratory class for the remaining three to four weeks. This ensures that the students receive more than the amount of laboratory work required by the AP. Students in AP Chemistry are expected to take the AP Chemistry Exam in May.

Goals of the course

Students are prepared to be critical and independent thinkers who are able to function effectively in a scientific and technological society.

Students will be able to analyze scientific and societal issues using scientific problem solving.

Students will be able to make an acceptable score on the AP Chemistry examination in May.

Methodology

At the beginning of each chapter the students are provided with an outline of the concepts for the chapter. The students will read the chapter in the text. Mini-lectures on the important points of the chapter are provided by the teacher. Most of the learning takes place through the problem solving packet. The students will solve problem sets that include problems from the text, old AP questions and free response problems, and other sources. Problems are solved numerically, but the students are required to add a narrative describing the important concepts and their thought process for each type of problem. This additional narrative provides a balance between strict problem solving techniques and an understanding of the patterns and relationships involved in Chemistry within the time constraints of the class.

AP Exam Review 3.0 weeks

Review of concepts via worksheets and study guides combined with practice test problems from past AP exams. Two full AP exams under AP exam conditions will be practiced prior to the AP exam. The last ‘mock’ exam counts as a portion of the students’ semester final exam.

Laboratory Program

The laboratory program is based on the recommended experiments from the AP Chemistry Course Description. All labs are performed by the students in groups of two to four students in the lab (no virtual labs). Prior to the AP Exam in May, most of the labs are conducted in a single 50 minutes class period with some final measurements conducted the next day (mass of filtrate after drying,etc). Approximately two times a semester the students will come in for an extended lab period on a Saturday. After the AP Exam the class will become strictly a lab class, and the students will perform 3 or 4 experiments with an emphasis on longer or multi-step labs. . Students keep a formal laboratory notebook that holds all their rough data, calculations, and conclusions. They are also required to turn in lab reports to be graded.

From the prerequisite first year Chemistry course, the students will have already performed all or part of the AP recommended labs numbers 1, 2, 4, 5, 7, 9, 13, 14, 18, 20, 21. Because of this, some concepts will be taught with a quick demonstration or mini-lab reminding students of the work that was done in the previous year.

The following labs will be full labs with write-ups (formal lab write-up in addition to work done in the lab notebook). Each lab will take one to two class periods to complete (50 minute periods).

Lab Experiments

A. Empirical formula of copper iodide

B. Synthesis of aspirin

C. Double replacement precipitate reactions (net ionic reactions)

D. Determination of molar volume of a gas.

E. Molecular mass of a volatile liquid (isopropanal)

F. Enthalpy (calorimeter)

G. Flame tests and atomic discharge tubes with spectroscopes

H. Molecular mass by freezing point depression

I. Kinetics of thiosulfate decomposition

J. Determination of equilibrium constant

K. Titration curve of strong/weak acid and strong/weak bases

L. Electrolysis of water

M. Colorimetric/spectrophotometric analysis

N. Synthesis of an organic compound

In each laboratory experiment, students will physically manipulate equipment and materials in order to make relevant observations and collect data; use the collected data to form conclusions and verify hypotheses; and communicate and compare results and procedures.

If the students have already learned the required lab techniques required for a specific lab, that lab will be an inquiry based type lab. Most of the labs done after the AP exam in May will be inquiry type labs.

Course Evaluation:

Quarter Grade: Semester Grade:

Tests 50% Each Quarter 20%

Quizzes and Assignment 30% Final Exam 20%

Labs 20%

Late and Make-up Policies:

Late: Simple Assignments (problems from the book)

No credit for late assignment.

Labs and Projects:

90% credit if 1 day late; 75% if 2 days late,

50% credit if 3 days late; no credit after 3 days late.

Make-up: Lab, quizzes, and tests must be made-up.

All of these will be made up outside of regular classroom times-either at lunch

or after school.

Academic Honesty: Students are expected to complete their own assignments. If two students hand in the same work they will both be given a grade of zero on the assignment. During laboratory experiments students may have the same lab data, but the write-up or the labs needs to be done alone.

Calculators will be checked before quizzes. If any illegal programs or data is found in the memory of the calculator the student will take a zero for the test.

Any cheating on a quiz, test or an exam will result in a grade of zero on the assignment.

Classroom/Lab Behaviour: Students are expected to conduct themselves in an appropriate manner in the classroom. All school rules will be followed in the classroom. During lab activities it is critical that the students listen and follow directions. Dangerous or malicious actions by a student in the lab will not be tolerated due to safety issues.
