Course Overview The goal of AP Environmental Science is to provide students with the scientific principles, concepts, and methodologies required to understand the interrelationships of the natural world, to identify and analyze environmental problems both natural and human-made, to evaluate the relative risks associated with these problems, and to examine alternative solutions for resolving and/or preventing them. Environmental science is interdisciplinary; it embraces a wide variety of topics from different areas of study. The curriculum draws upon various scientific disciplines including: Earth Systems and Resources The Living World Population Dynamics Land and Water Use Energy Resources and Consumption Pollution Global Change In addition the course will provide students with the scientific principles, concepts, and methodologies required to understand the interrelationships of the natural world including: Analyzing and interpreting information and experimental data, including mathematical calculations. How to identify and analyze environmental problems, to evaluate the ecological and human health risks associated with these problems, and to critically examine various solutions for resolving or preventing them. A laboratory and/or field investigation component. A minimum of one class period per week will be spent engaged in laboratory and/or field work. The following themes will be introduced and revisited throughout the course as they represent unifying themes in the study of environmental science: 1. Science is a process. Science is a method of learning more about the world. .Science constantly changes the way we understand the world. 2. Energy conversions underlie all ecological processes. Energy cannot be created; it must come from somewhere. As energy flows through systems, at each step more of it becomes unusable. 3. The Earth itself is one interconnected system. Natural systems change over time and space. Biogeochemical systems vary in ability to recover from disturbances 4. Humans alter natural systems. Humans have had an impact on the environment for millions of years Technology and population growth have enabled humans to increase both the rate and scale of their impact on the environment. 5. Environmental problems have a cultural and social context. Understanding the role of cultural, social, and economic factors is vital to the development of solutions. 6. Human survival depends on developing practices that will achieve sustainable systems. Course Structure and Prerequisites Students enrolling in AP Environmental Science must have completed 2 years of science course work. The class meets 53 minutes a day, 3 days a week and one 90 minute lab day per week. This time frame provides ample time to investigate environmental topics in depth using a variety of methodologies including lecture, lab and field activities, video with pre- and post-viewing activities, primary source readings with seminar style discussion, simulations and case studies.

Students will also complete pre-lab assessment questions and/or a data table before the actual experimentation. A fully typed lab report is due one week after the laboratory procedure. **Results, Analysis, and Conclusion must include mathematical and graphical support in all applicable situations** Projects (daily, weekly, or extended) are included in the labs aspect of the final grade. Current Events Environmental science is a rapidly changing field; there are daily news reports and scientific findings adding to our collective knowledge. You are to select ONE article twice a month related to the current topic of study. For each article write a BRIEF summary and personal response to your article. Include all environmental topics covered in the article and evaluate the article for bias. These are to be turned in on alternate Fridays.
