    In this activity, students set up an experiment to determine the biodegradability of different substances.

    By the end of this activity, students should be able to:

    • organise a group of items into categories
    • carry out a simple experiment
    • understand that some materials are biodegradable and others aren’t
    • explain what might affect how quickly something degrades
    • make predictions about the biodegradability of materials.
