Teacher Resources - Video Lesson September 2009

Ray Capture

Welcome to SBERPs First Video-Enhanced Lesson!

This exercise is designed to introduce students to the Shark Bay seagrass ecosystem and how scientists collect information to help them understand the relationships of some its important species. The lesson starts with an exploration of the seagrass beds themselves and builds to include the larger animals and the role they play in the ecosystem. Some of the key concepts in this lesson are interdependence, the flow of energy in ecosystems, the important role of predators, and the practice of science (hypothesis generation, data collection, hypothesis-testing). The lesson can be taught at a variety of grade levels and we would love your feedback on how we can improve any of these materials or make them more specific to particular grade levels. Please send any comments or ideas for other lessons/concepts to Mike Heithaus.
