Activity Introduction

green-waste-grinder-heroQuick summary: Students design and conduct a survey of other students, staff and parents at their school to see how well and/or frequently green waste bins are used at home, and what the barriers are to using them more often. Data acquired through the survey can be used in the Considering Social Action activity – Green Waste Messages.

Back-to-Earth-logoFollowing these lessons plans is an ideal way for your students and the community to tune in to what happens to green waste once it is collected in a kerbside bin. The Back to Earth initiative is about connecting people with what happens to green waste once it leaves the garden, how it is processed, what it is used for at the end of this cycle and why its important to put the right things into the bin!  

Join thousands of others who have learnt about the benefits of using their green waste service correctly, for their communities and for the planet.  Don’t forget to check out the Back to Earth initiative website: www.backtoearth.vic.gov.au – to learn more.

Learning goals:

  • Students understand the environmental problems associated with sending green waste to landfill.
  • Students recognise the benefits recycling green waste and composting.
  • Students understand how to design and conduct a survey of the school community.

General capabilities: Critical and creative thinking.

Cross-curriculum priority: Sustainability – OI.8.

Overarching learning goal: By participating in this activity students will understand the environmental problems associated with sending green waste to landfill and will recognise the benefits of recycling green waste and composting. Students will also understand how to design and conduct a survey of the school community.

Teacher content information: Many people think that sending green waste to landfill is fine. It’s natural right?? Surely it just breaks down and creates good soil that helps the environment?? No, sadly, this is not what happens at all.

Landfill sites are essentially great big piles of rubbish. There is no air in these great big piles and this means nothing much breaks down in them at all (did you know that old landfills are now being treated as archaeological sites because the waste is so well preserved?!). The only organisms that can survive in a landfill are bacteria which decomposes the waste anaerobically (without using oxygen). Unfortunatel
