Locker Alarm Science Challenge

The locker alarm works by when you open the locker door it completes a circuit and sounds an alarm. We did not complete it, but we know how it works. We had batteries on the side of the door and taped wires to it so it could extend to complete the circuit when the door opened. We also had the alarm piece taped to the door so when the door opened the wire would move across to then touch the alarm and sound it.
