AP Environmental Science 2011-2012 Course Overview Advanced Placement Environmental Science is a full-year laboratory science course. The goal of this course is to provide students with a broad background in a wide range of topics in Environmental Science in preparation for the Advanced Placement examination in May 2010. It is the expectation that all students in AP Environmental Science will sit for the AP exam. Methods Instruction will consist of lecture, discussion, and demonstration. At least one laboratory or field work experience will be included each week. Laboratory work reflects the broad range of topics and methods practiced in this field. The activities include traditional laboratory experiences, longer-term experiments, and research/analysis of publicly available data. In all cases, there is an emphasis on use of the Scientific Method when applicable, critical thinking, collection and mathematically rigorous analysis of data, and problem solving. Clear, accurate communication of experimental findings is essential in Science, accordingly, appropriate graphical and written presentation of lab work is expected. (Please note that appropriate clothing should be worn for field experiences – this would include closed-toed shoes, long pants, sun hat, and insect repellent and sunscreen as needed) Several research assignments will be included. In all cases, there is an emphasis on identifying a problem, challenge, or topic, and solutions or favorable path forward. Research work then consists of two components: background data on the current situation and projections or suggestions for the future. Written assignments will include in-class work, research projects, homework, and laboratory reports. Assessment will be based on tests, weekly quizzes, and written assignments that will count as 70%, 10%, and 20% respectively towards the overall marking period grade. All tests will be “AP style” and consist of multiple choice and short answer sections. Calculator use is not permitted on any test. Text Environmental Science: Toward a Sustainable Future, R.
