Aquatic Ecology Field Study Procedures
Author: 4. Draw a map of the aquatic ecosystem Laurie Rosenberg, Muhlenberg College being studied and identify key Grade Level: 5-8th landscape features that contribute to Lesson Time: 2.5-3hours the healthy functioning of the pond Suggested Class Structure: Small ecosystem. groups 5. Use an aquatic plant wheel to Subject Areas: Science, Language Arts identify common wetland and aquatic plants and describe how they BACKGROUND contribute to the pond ecosystem 6. Collect and observe algae living in See individual lessons. the pond and describe how they are influenced by water quality and what contribution they make to the aquatic ecosystem. 7. Describe the key features of the pond ecosystem and summarize the GOAL interactions between the chemical, physical and biological features they Students rotate through a series of have observed and studied. stations, investigating a different aspect of aquatic ecology at each station. At the end of the field trip, students will MATERIALS discuss how the pieces fit together to determine the overall health of the • Alkalinity test kit (Lamotte # 4491) aquatic ecosystem. • Barometric pressure probe • Board • Bottle of distilled water OBJECTIVES • Calcium test probe • Calculator The students shall: • Carbon Dioxide test probe • Collection bottle 1. Use chemical and physical test to • Collection trays determine water quality. • Compass 2. Identify aquatic macro-organisms • Conductivity test kit (Lamotte and explain what their presence #5-0039) indicated about the conditions of the • D nets habitat in which they were found. • Dissolved Oxygen probe 3. Make observations about soil color, • Dissolved Oxygen test kit (Lamotte structure, and texture and draw #7414) inferences about the drainage • Field microscope conditions in the area around the • 18 flags ponds and how this relates to water • Geotechnical gauge (Soil quality. color/texture guides)
