Quick Summary: This lesson incorporates clips from Blue The Film as learning inspiration. Students delve deep into the mathematics behind one of the big environmental problems of today: plastic waste. Students explore what it would mean if we addressed one part of this problem; specifically cutting down on the millions of plastic toothbrushes that are thrown away in Australia each year. This lesson invites students to critically evaluate statistics and use relevant data to calculate the impact of this environmental change.
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 will understand the positive impacts of reducing plastic waste through mathematical investigation.
