Quick summary: 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.
Blue is a feature documentary film charting the drastic decline in the health of our oceans. With more than half of all marine life lost and the expansion of the industrialization of the seas, the film sets out the challenges we are facing and the opportunities for positive change. Blue changes the way we think about our liquid world and inspires the audience to action. Find out how to screen or download the film. Along with the film is an ambitious global campaign to create advocacy and behaviour change through the #oceanguardian movement. To become an ocean guardian, see the website.
- Students understand the difference between a food web and a food chain.
- Students understand how each species in a food web is integral to the health of the whole web.
- Students recognise how food webs can be used to help us understand the health of marine environments.
