Description: The biology unit is centered around biological assessment of river or stream ecosystems. Students learn to use biological diversity and water quality indices to better understand the aquatic ecosystem. Students also learn how to conduct habitat surveys and environmental assessments to investigate stream quality and the interactions between humans and rivers. The students learn field and laboratory techniques while working together to collect and interpret their data. Field studies are designed to require a minimum of equipment and the planning and methodology is systematically laid out for teachers. Rivers Biology also includes journal sessions, games, experiments, and assessments to reinforce the field and laboratory concepts.
