It's Electric!
This is a picture of our class making circuits with a D cell, some wires and a light bulb. We learned that energy alway travels from the negative side of a d -cell because electrons travel the same direction.
Also here are some pictures of edible circuits that we made in class. These circuits will make your eyes light up and your mouth start to drool!
Fun facts
In case you did not know this, the difference between an open circuit and closed circuit is that a closed circuit is when a handle (or what ever you are using as a switch) is touching the clip so that the electricity can pass through. The open circuit is when the switch is not touching the clip so the electrons can not pass through.
