Course Description: Aquatic Science is an upper level, year-long science course.  Students study a variety of topics that include: components of an aquatic ecosystem; relationships among aquatic habitats and ecosystems; roles of cycles within an aquatic environment; adaptations of organisms; changes within aquatic environments; geological phenomena and fluid dynamics effects; and origin and use of water in a watershed.

Course Goals: Students will gain an overall understanding of aquatic ecosystems including saltwater and freshwater ecosystems and the flora and fauna found in them. They will also learn about the geological formations that form the Earth’s oceans & rivers, and the effect these bodies of water have on weather. Students will also acquire the necessary skills, responsibilities and knowledge to be good stewards of freshwater and marine environments.  A reading of the course sequence will give a more detailed view of our course goals.
