P5DK had great fun trying to work out which conductors changed the brightness of the bulb. First of all they had to understand the difference between an insulator and a conductor. After that, they all learnt how to build a circuit using wires, bulb, bulb holder, batteries and battery holder. Finally, they used a variety of different conductors in the circuit to see if they affected the brightness of the bulb. Here are some photos to see then in action.
