Students' central challenge is to determine the food web of a local site. By investigating a familiar area, such as their schoolyard or a neighborhood park, students see their everyday environment as an ecosystem of which they are part. After exploring outdoor study plots, students design investigations to answer thier questions about animal feeding behaviors. This unit develops students' communication and application skills through assessment activities. Students set up outdoor study stations to teach others about food web clues, and create an exhibition to share their findings.
