Solar4Scholars: Make an Electric Circuit

What you need

  1. Lantern battery - DO NOT USE ANYTHING HIGHER THAN A NINE-VOLT BATTERY
  2. Small light bulb/lamp or small motor
  3. Wire to connect battery and lamp terminal (bare wire, not plastics or rubber covered)
  4. Wire clippers

Instructions

  1. Cut three pieces of wire.
  2. Connect the wires from the battery terminals to the lamp terminals - lamp or motor will light up or run.
  3. Take the third wire that was laying across the other two wires. Take the wire clippers and cut one of the wires leading from the battery to one of the lamp terminals. The lamp or motor should also go out or stop.

What you will learn

When the third piece of wire is dropped across the two wires leading to and from the lamp, the wire created a "short circuit." This doesn't mean the electricity took a shorter course, it just took an easier path. When you cut the wire with the clippers, you created an "open" circuit. Place a switch on this wire and you will create the same type of circuit you have with any electric light.
