Activity Introduction
Quick summary: This lesson incorporates clips from Blue The Film as learning inspiration. Students will understand the importance of conserving our oceans by exploring the real world problem of by-catch and overfishing. They will mathematically investigate the problem and use data to plot graphs showing how by-catch is influencing the number of marine animals in our oceans. Students will then investigate ways in which the problem can be reduced and fishing practices can be changed.
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.
