Electricity
Learn About Electricity: Learn the basics of electricity as a form of energy, what is a power source, a circuit and a conductor or insulator. Better yet, the pictures make it easier to understand these concepts.
Let Schoolhouse Rock introduce you to some of the people that made important discoveries in the history of electricity.
