Electricity and Circuits 4th Grade

Electricity is energy that powers things. Without it, there would be no light bulbs, cars, computers, TV's, powered stoves, fridges, and gaming consoles. We use electricity every day, and it may seem simple, but circuits can be very complicated. First there are open and closed circuits. All circuits need a power source to work. They also need to be a Closed Circuit (below). A battery has a positive (+) side and a negative (-) side. The positive one gives the energy and the negative on receives the used energy. The circuit MUST start at the positive side and end at the negative side of the battery. This is pretty basic stuff, but it can be WAY more complicated.
