Creature Catcher Halloween STEM Challenge

Creature Catcher Halloween STEM Challenge


Students work in partners or groups against a criteria and constraints list to design a device to catch as many “creatures” as possible.

Looking for a fun Halloween activity that incorporates science, technology, engineering, and/or math? Halloween STEM / STEAM Challenges are collaborative, brain-busting work disguised as fun!

The basic premise:

Students work in partners or groups against a criteria and constraints list to design a device to catch as many “creatures” as possible. If you aren’t allowed to do Halloween activities, you can use this to start off a unit on spiders, food chains/webs, energy pyramids and more!
