Micro STEM @ Aurora – Friday: Homemade Batteries

On our final day of Micro STEM, the campers made their own batteries! First campers made a hand battery. The hand battery works with a piece of aluminum and a copper sheet, which are conductors. They used their own body’s electric charge by placing a hand on each of the plates, then measured the electrical output with a multi-meter.

Ask your student:

What materials did you use for the aluminum air battery? Aluminum foil, paper towel, salt water, and activated charcoal.
