Year 4 has been studying electricity this term. We have been discussing and discovering how electricity travels through wires and other conductors. At first we just made a circuit to light up the bulb. Then we moved to putting conductors in the circuits like pins, scissors and even the metallic door handle in our class. The final step was to make our own switches. We achieved this by placing to pins on a sponge and sliding a metal clip in between the clips which resulted in the circuit to work.
