Years 7 to 9
Students audit the contents of a typical school bin, by categorising, then counting the different types of rubbish. They research how long it takes for different items to break down, and then create a 'decay timeline' for the types of rubbish that were found in the bin.
Students then assess what rubbish might be remaining in the schoolyard after different periods of time, and make some suggestions about rubbish disposal at school.
