    General Course Structure and Assignments

     The AP Chemistry course is designed to be the equivalent of a general chemistry course usually taken during the freshman year in college. This is a very demanding class in both time and effort required. Students who are heavily involved in after school activities and /or jobs will have to learn to budget their time very carefully. Students MUST have time available before school or immediately after school to get extra help or make up lab work when necessary.

     

    Much of the work involves solving math-type story problems therefore students need to be concurrently enrolled in Algebra II or above.  Homework is assigned each day. It will include memory work along with web-based problem solving and is likely to take approximately one hour for every hour spent in class. Home work is due at the beginning of each class period. Late homework will not be accepted.

     

    Once each week the class will have a lab. If you are unable to complete the lab during class time you will be required to complete it after school.

    Review for the AP Exam (2.0 weeks)

    Students will have two practice exam opportunities, and receive instruction on the approach to answering the different types of questions.

     

    General Laboratory Expectations

    §         Making observations of chemical reactions and substances.

    §         Recording data.

    §         Calculating and interpreting results based on quantitative data obtained.

    §         Communicating effectively the results of experimental work.

     

    Students are required to submit a complete report for each lab experiment, including a hypothesis, procedure, observations/data, calculations and a conclusion. Reports are recorded in a lab notebook. Students will be called upon to make presentation to the class about their hypothesis, procedure, observations/data, calculations and conclusion. This will allow students to collaborate and gain insight s into variance and sources of error. (A5 &A7)

    Grades

    The Grades which students receive in the AP Chemistry course are independent of the grades they receive on the AP Chemistry exam. In fact, AP Exam grades are not announced until July, long after teachers have turned in their course grades. Students who work hard and keep up will receive either A or B grades. However, those who fall behind and give up on the course may receive grades lower than this. Grades are determined by tests (about 40%), lab reports (about 30%) daily homework (about 30%).

     

    The grading scale for this class is:

    80-100%: A

    70-80%: B

    60-70%: C

    50-60%: D

    Below 50%: Fail

     

    In addition, for the students who meet the following three requirements:

    1.     Complete ALL homework and lab work on time

    2.     All homework and lab work turned in is “of Quality”

    3.     Receive a “pass” (i.e. “3” or better)on the AP Chemistry exam

    their course grade will reflect an “A” grade. If necessary, their grade will be changed to an “A” grade in September after AP Exam grades are released.

     

    Quizzes will be given at random. Tests will be given at midterm and the end of all four quarters. Students will not be given chapter tests. No notes will be allowed for tests. Students will be given the same note sheet that is provided to them during the AP Exam. This policy is to help you become comfortable with the criteria for the AP Exam.
