Grading Procedure: Grades will be determined by a student’s completion and accuracy on: Daily homework assignments/problem sets from the text and released AP Examinations Formal lab reports and projects Quizzes Tests Grades will be computed as follows: 1. Homework: 15% 2. Lab Reports and projects: 35% 3. Tests and quizzes: 50% Grade Distribution: Q1 20%, Q2 20%, Q3 20%, Q4 20%, Midterm 10%, Final 10% Tests: A test will be given after each Chapter. A comprehensive exam will be given during the midterm covering Q1 and Q2 material. A final exam will be given during Q4 prior to the AP Course exam. Final Project: All students are required to complete a final research project in the 4th quarter. The project will entail researching a topic in chemistry (from a list provided by the instructor), submitting a research paper and presenting the results to the class. This project is mandatory and counts as 10 % of your final grade. Description of Course: This AP Chemistry course will provide students (juniors and seniors) an intensive academic experience that will parallel what would be studied in a first year college chemistry course (lecture and lab). This course is designed for students who have successfully completed Honors Chemistry Honors and desire a stronger background for college. Students selecting this course must have the ability to work both collaboratively and independently and have sufficient time to handle a large volume of material. This course will be an excellent preparation for the SAT achievement test and AP Chemistry examination. Students will be expected to take the AP Chemistry exam. AP Chemistry meets each school day for 43 minutes and there are two additional periods making the class a double period on these days. One day prior to chapter tests, the class will work in small study groups reviewing to prepare for the test. In addition, each chapter will include a free-response quiz in order to practice taking this part of the test. During at least one of the double periods students will be engaged in hands-on laboratory work integrated throughout the course and accounting for over 25% of class time. Often, these lab sessions will 1 extend into the students’ own time after school. [CR5a] The instructor and students should plan to be available for at least 45 minutes after school on designated lab days in order to complete laboratory work. Objectives Students will: 1. Learn the inquiry process through hands-on lab experiments. 2. Gain an understanding of six big ideas as articulated in AP Chemistry Curriculum Framework. [CR2] 3. Apply mathematical and scientific knowledge and skills to solve quantitative, qualitative, spatial and analytical problems. 4. Apply basic algebra, arithmetic and geometric concepts. 5.
