Activity Introduction


In this lesson, students will be immersed in, and connect with, the documentary film 2040, focusing on the topic of food chains and food webs. Students begin by completing a Flipped Classroom preparation activity to introduce the topics of food chains and food webs. Back in the classroom, students are asked to share what they learnt about food chains and webs before exploring energy flow and trophic levels in a marine food web. They then participate in an activity to demonstrate how food webs can collapse when organisms within the food web experience a decline in numbers.


Students then explore how seaweed farming could improve marine food webs as well as benefit human populations. Finally, students are asked to think about what other actions humans can take to improve marine food webs and to communicate their ideas through a poster or infographic.


Learning Intentions

  • Students will understand what a food chain is and what a food web is.

Teacher content information: A 2018 study by The University of Melbourne on the thoughts and concerns of young people from Generations X and Y found the number one concern across both groups was lack of action around climate change. In particular, "Generation X worries what climate change will mean for their own children, while Generation Y is concerned about the impact on future generations" (The Educator). The report indicates that young people have
