AP BIOLOGY SYLLABUS Course Overview AP Biology conforms to the standards as outlined by the College Board. The topics covered include biochemistry, cell structure and function, metabolism, genetics, DNA structure and technology, evolution, classification, plant anatomy and physiology, animal anatomy and physiology, and ecology. When categorized into three general areas, the topic percentage coverage is as follows: I. Molecules and cells – 25% II. Heredity and evolution – 25% III. Organisms and populations – 50% With the introduction of each new topic, the eight major unifying themes in biology are consistently applied across the entire curriculum. The eight major unifying themes in biology are as follows: 1. Science as a process 2. Evolution 3. Energy transfer 4. Continuity and change 5. Relationship of structure and function 6. Regulation 7. Interdependence in nature 8. Science, technology, and society The class meets 48 minutes per day, five days per week. In addition, students are required to attend one two-hour lab session (after school) each week. All lab activities are hands-on, with students working in groups of two. (In the event of an extended absence in which the consumables are no longer available, a computer-simulated/virtual lab will be an acceptable alternative, with the required lab report submitted.) Lab sessions will include the 12 required AP Biology labs, in addition to approximately 30 other labs and activities. Daily warm-ups consist of five questions in the AP exam style. A free-response question accompanies each exam. It is scored on a 10-point system. Textbook, Lab Manuals, Resources Biology, 6th Edition, Neil A. Campbell and Jane B. Reece, 2002, Benjamin Cummings.
