Today’s After School Program STEAM Campers learned about circuits. Circuits need to be circular – they need to have a complete pathway for electrons to flow through. We needed to have conductive material (we used tin foil) to go from the power source to the light and then back again so the electrons can go out and come back. A battery gave the force to make the electrons move through our circuits. When the electrons got to the Christmas light, they gave it power to make it work. Our circuits also have a switch so that it could be turned on and off – we used brass brads. This weeks circuit was a series – which means all of the parts are connected on the same pathway one after another. Next week we will try parallel circuits.
