In technology we have been putting together circuits. To make a circuit you will need a battery, a light bulb, wires, and a switch. The goal is to make the lightbulb light up. A circuit takes the energy and electricity from the battery and transfers it to the lightbulb. In class we have only been using lightbulbs in our circuits, but you can also use other things instead like a fan. All a circuit has to do is just transfer energy and electricity to an object to make it do something. For example, the circuit would make the lightbulb light up and the fan start blowing.
