8 Backyard Science Experiments for Kids

This fun experiment is a great way to demonstrate the principals of electric current for older kids. You’ll need a small device to “power up,” plus lemons and a few items from the hardware store. Be sure to have your phone ready to capture the expressions on your kids’ faces when they see it work! Check out Holly and Rachel’s blog for the full instructions.

Science lesson: The citric acid in the lemon reacts with the two different metals, pushing the ions in one direction, creating an electric current.
