I learned about how to make a circuit in 3rd grade. First I got an empty paper towel tube. Next I got one battery and two wires and one beeper. Then I got one switch. Then I picked up the empty paper towel tube and wrapped it around my circuit. I made the switch stick out. When you touch the paper clip to the metal the beeper goes be be be be. That is all about my circuit.
