Lesson summary
In this activity, students look at waste and the time frame 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 archaeologists undertaking a dig of a kitchen 100 years in the future and are asked to describe the condition of the items that they find.
Learning goals:
- The aim of this activity is to raise awareness of the rate of waste material breakdown and how this can take many, many years.
