SYLLABUS for AP CHEMISTRY 2011-2012 Class Prerequisites The prerequisites for Advanced Placement Chemistry are: Conceptual Physics, 1 st year Chemistry, and at least 2nd year Algebra. Additionally, students must be highly motivated and have the recommendation of their previous science teachers and the Office of College Counseling. All students are counseled on the course requirements prior to the start of the course to ensure they have a full understanding of the time and effort that will be required throughout the year. A work packet is provided to each student for their use during the summer prior to the course. Course Overview The Advanced Placement Chemistry course is a second year chemistry program open to Junior and Senior students who meet the prerequisites. Many of the topics required of an Advanced Placement Chemistry course have been covered in the first year course. Those topics will be reviewed and discussed in greater depth. The time allotted weekly for this course is four periods of 45 minutes and one evening lab period of 120 minutes for a total of 300 minutes per week. With 300 minutes available per week, the course is heavily lab based (120 minutes/week). The College Board’s twenty two recommended chemistry labs are used during this year-long course. Additional hands-on activities are added. The lab facility in the Clay Center has state of the art equipment and complies with all appropriate safety standards. Students are required to keep a Chemistry notebook and a separate Chemistry Lab book. Instructional materials All AP Chemistry students are provided with the following: Chemistry: The Central Science, 12th edition Authors: Bursten, Brown, and LeMay © 2012 AP Test Prep Series: AP Chemistry Author: Waterman © 2012 Various computer simulations; tutorials; video programs; relevant news articles; and Chemical Journals Course Outline Students will be prepared: to be independent and critical thinkers, to make relevant observations, collect data, form conclusions, and to communicate with others in written form. Instructional strategies will include: problem sets; AP practice tests; project assignments; class discussions of current issues (emphasizing critical thinking skills); lecture/demonstrations; research papers; and laboratory. activities.
