Quick summary: This lesson incorporates clips from Blue The Film as learning inspiration. Students perform an analysis of and design solutions to combat one of our major environmental issues; litter. Students use a study of a local site at school to calculate the amount of litter at a larger scale. Proportional thinking is embedded in a meaningful problem that students themselves can address.
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 here. 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 will be able to use a sample area to estimate and understand the amount of litter in larger areas.
