Today in class we learned about circuit. We also created a circuit which gave energy to a light bulb. Some important things that we learned about circuits is that you always need a switch because without one you won’t be able turn off your light bulb.You need to make sure that everything is connected when making the circuit, otherwise the energy won’t flow through the objects which won’t allow the light bulb to light up. You most obviously need a battery since your light bulb won’t work without it. With this information we lighted up a lightbulb. It was so much fun!!!!
