Quick summary: In this activity students investigate the composition of recyclable materials and look at how the composition affects the rate of break down. In two competing groups, student work to order a range of different waste materials in the order that they break down from fastest to slowest. Finally they are asked to create a poster or infographic describing break down rates of waste materials and tips for reducing waste.
This lesson has been developed as part of the Schools Recycle Right Challenge for Planet Ark’s National Recycling Week. Register your lesson or other activities so they can be counted towards the national achievement and to receive other free support materials.
- Students understand that waste materials have different rates of decomposition.
- Students recognise that these rates can vary from several weeks to forever.
- Students understand that we all have a role to play in reducing waste in our environment.
