Quick summary: In this activity students look at how climate change may affect the food webs and the trophic relationships within them. Students begin by refreshing their knowledge of food webs by working as a class to create an African grassland food web. Students will then break into groups to explore a number of different ecosystems and will investigate how these ecosystems might be impacted by climate change. Students are asked to create a short film or animation sharing their research.
In 2017, WWF is celebrating 10 years of Earth Hour and 10 years of progress on changing climate change. Our actions on climate change will shape the future for our children. They know more about climate change than any other generation. And they have extraordinary views on what they want for their planet. You and your students can become a part of the movement and start to take action on climate change by visiting earthhour.org.au to register for Lights Out or find your local event. Take part and register for Earth Hour Schools Day on Friday the 24th March and donâ€™t forget to switch off on Earth Hour, on Saturday 25th March 8:30-9:30pm. Switch off to #JoinTheFuture.

Australian Curriculum content description:
Year 7 Science
- Interactions between organisms can be described in terms of food chains and food webs; human activity can affect these interactions (ACSSU112)
- Identify questions and problems that can be investigated scientifically and make predictions based on scientific knowledge (ACSIS124)
- Summarise data, from studentsâ€™ own investigations and secondary sources, and use scientific understanding to identify relationships and draw conclusions (ACSIS130)
- Communicate ideas, findings and solutions to problems using scientific language and representations using digital technologies as appropriate (ACSIS133)
