Lesson summary

In this activity, students examine and weigh the waste that has been collected over one week from the teacher’s household. They will also bring to class one item of packaging that they think is excessive. Students will then be asked to think critically about the amount of packaging that is used to wrap the things we use every day, and to think creatively about how this packaging could be reused. This activity is in two parts and requires some preparation to collect one week’s worth of rubbish and examples of excessive packaging.

Learning intentions:

Students will...

  • learn that we create a lot of waste in our daily lives
  • understand that we can recycle much of this waste
  • understand that we can think carefully about what we buy so that we aren’t contributing unnecessarily to the waste problem.
