Blue - Ocean Food Chains and Food Webs

This lesson incorporates clips from Blue The Film as learning inspiration. Students investigate the differences between food webs and food chains, and examine how these visual tools help us to understand the health of the oceans. Students begin by defining a range of key terms related to food webs and food chains, and then analyse models to identify the flow of energy. Students will then test the fragility of a food web, seeing what happens when species within that food web are removed. Finally, students examine some of the ways humans impact marine environments, working in groups to create a poster that describes a food chain of a marine species under threat from human behaviours.
