Lemon Battery Circuits

I facilitated a day-long lemon battery circuit camp. We created circuits that light up an LED using lemon juice. The circuits were built using copper wire, zinc rods, an LED and paper towel. I prepared 1″ pieces of zinc rod, pieces of paper towel and 3″ pieces of copper wire. We each inserted 8 zinc rod pieces into the side of a cork. We wrapped the paper towel around the zinc rods and then wrapped copper wire around the paper towel. Copper wire made the connection between each zinc rod and the LED. To make the LED light up, we dropped lemon juice onto the paper towel pieces.

Each person created their own art project around the lemon battery circuit.
