AP Environmental Science Course Syllabus Course Objectives: This course is designed as the equivalent of a 1-semester college course. Students will be introduced to the fields (biology, geography, sociology, economics, natural resource management, chemistry, geology, law, and politics) used in understanding both the workings of and human interactions with our environment. Topics include: human population growth, energy resources, land and food resources, water resources, air pollution, global climate change, and human health and toxicology, as well as a review of ecology and species diversity. Sustainability is a unifying theme throughout the course, as is an understanding of the linkages between ecosystems. This understanding will give students a greater appreciation for and better stewardship of the world in which they live. Texts: 1. Environmental Science, 13th Ed., Miller & Spoolman, Thomson/Brooks/Cole, 2011. (ISBN-10 – 0495560162; ISBN-13 – 978-0495560166 (paperback)) 2. AP Environmental Science Supplement (online). a. This is a collection of all homework, lab, and additional reading assignments created by our team of AP Environmental Science teachers. 3. Song for the Blue Ocean, Carl Safina. 1999. Holt. (ISBN-10 – 0805061223; ISBN-13 – 978-0805061222) Grading: 30% 20% 10% 20% 20% = = = = = Tests Lab and Homework Quizzes Textbook Reading quizzes Projects (journal write-ups, presentations, final book report, etc.) Trimester Exams Tests will consist of approximately 30 multiple choice questions and written response questions and will be 45 – 60 minutes long. The multiple choice section should take approximately 2/3 of the test time and the written response section 1/3 of the test time. Homework Assignments are expected to take 30 – 45 minutes per night. These include: assigned readings, worksheets, labwork, project preparation, and studying for tests and quizzes. Labs – We devote a least one class period per week to lab and/or field work. Lab and Homework Quizzes will be given in class towards the end of each unit. The teacher may allow students to use their work in an open-book format and/or may collect the work as well. If students haven’t completed the homework and labs thoughtfully ahead of time, they won’t be of any use on the quiz, given the nature of the questions. Textbook Reading Quizzes are intended to reinforce key concepts in the textbook readings. They are open book, but students must complete the quizzes by themselves. Projects include: oral presentations, poster presentations, a book report, and current/relevant event ongoing Media Journal Entries. The Media Journal Entries consist of brief analyses of both classic environmental writings and current event topics. Because the Entries vary, specifics for each will be explained by the teacher as needed. Book Report will be due two weeks after the AP exam in the spring. Carl Safina’s Song for the Blue Ocean is a beautifully written study of the state of our world’s oceans. Students will choose one of the book’s three sections to read, and will refer to a series of prompts that ask them to analyze Safina’s viewpoint and put the information presented in this book into the context of what we learned throughout the year. We choose to read this book in an effort to address a topic which unfortunately gets short shrift in our textbook. Trimesters One & Two Exams are similar in format (multiple choice and essay) to the tests except that they are longer and makes an attempt to codify and unite multiple themes and concepts covered throughout the first two-thirds of the course. There is no Extra Credit in AP Environmental Science.
