To make a model of hydroelectric energy, we made water wheels. We did not make electricity, though. I wanted students to see how water could be used to turn the turbine, which then creates electricity. Originally, I would use the bottom of aluminum pie pans. However, to reduce costs, I copied a template onto card stock. It only lasts a short time, but students are still able to get similar results.
If you would like to re-try this model with your child at home and use an aluminum pie pan, the template below and can be traced onto the pan. Or, you can attempt with card stock again! :)
