Year 7 have a short fuse

Year 7 are learning about electricity and this week we found out about fuses;. We mimicked the action of a fuse in an overloaded circuit by making a tiny wire out of aluminium foil, setting it up in a circuit with a bulb, then creating a short circuit across the bulb. Here’s what happened!

It might not look too safe in these pictures, but a fuse is actually a safely device! It burns through and breaks the circuit, stopping a big fire somewhere else.
