Overarching learning goal: Students are given a worksheet showing three eras from the past and one from the future showing the changes in the ways that people have used materials and disposed of their waste over the past 400 years. They are asked to colour in the drawings and complete the drawing for the future scene and predict the types of waste disposal that will be available in the future.

Student Worksheet

Where has waste been and where is it going? 

The amount of waste that humans have produced has changed a lot over the past 400 years, particularly in Australia. Indigenous Australians used only natural materials for all their needs, while European settlers introduced artificial materials and manufacturing techniques that changed consumption patterns and associated waste.

In the past, what did Indigenous Australians use to hunt, keep warm, gather food, build shelters and make tools and weapons. Consider the following questions:

  • Where did they get these things?
  • If things broke or wore out, what did they do with them? 
  • What did they eat?
  • Where did these things come from? 
  • What do you think they would have done with bones, uneaten food and shells ? 

 Now think about the way we all live today. 

  • Where do we get all the things that we eat, live in, wear and use? 
  • If things break or wear out, what do we do with them? 
  • What do we eat? 
  • What do we do with our food waste?
