  • Beakman's World: Basketball and Circuits

    Beakman explains how the prongs of cords are needed to complete the circuit of electrons flowing (electricity). He then does a skit where each member of a basketball team is an electron. They stand in a circle (to be a circuit) with Beakman as the battery. Beakman starts passing the ball (charge) around the circle and when the ball gets to the hoop, it goes in and lights the lightbulb. A player is removed and the circuit is broken so the bulb goes out. Beakman then explains how this relates to plugs, and then he demonstrates how a cord is actually two wires side by side to create the circuit to power an appliance.
