Activity Introduction

Quick summary: Students look at waste and the time it takes to decompose. Students are asked to order a selection of waste materials into the time it takes for them to break down. In the closing activity, they will act as archeologists undertaking a dig of a kitchen 100 years in the future and are asked to describe the condition of the items that they find.

 

Following this lesson plan is an ideal way for your school to take part in Schools Clean Up Day or a Clean Up on any day of the year. You’ll be joining thousands of amazing teachers in making a difference and creating positive environmental change.

 

Learning intentions:

  • Students raise their awareness of the rate of waste material breakdown and how this can take many, many years
  • Students build an understanding of the differences between biodegradable and non-biodegradable items
  • Students take responsibility for their own waste footprint.

Teacher Preparation

Learning intentions: Students will...

  • ... raise their awareness of the rate of waste material breakdown and how this can take many, many years
  • ... build an understanding of the differences between biodegradable and non-biodegradable items
  • .. take responsibility for their own waste footprint.

Success criteria: Students can...

  • ... know how long it takes different waste items to break down
  • ... communicate messages around waste.

Teacher content information: Biodegradation times depend on the environmental conditions. Materials will break down faster when exposed to the elements (sunlight, heat, rain, etc.) and decomposers (fungi, bacteria, insects and other invertebrates). Landfills are not ideal environments for decomposition, so trash in landfills takes much longer to break down.
