We got crocodile clips, a light bulb in a holder and a battery. In our groups our challenge was to find a way to make the bulb light up.  We tried different ways. We discovered that we had to connect  one end of the crocodile clip to the metal part of the bulb holder. The other end had to be connected to the battery.We had to do the same with another crocodile clip. We had made a circuit.

We drew pictures of clowns and used the bulbs to give them a shiny nose.
