This activity challenges students to look for items in their homes that are considered “waste” or do not get used anymore. In finding these items, students will also be challenged to consider reasons why they throw things away or stop using them. This activity is meant to be a fun way to encourage students to consider their environmental footprint and actions they can take to reduce waste.

This activity is designed as a precursor to the Trash To Treasure Design Challenge.
