How does a circuit work? LKS2 investigate

Last week we made bulbs light, motors turn and buzzers buzz, but WHY and HOW are these things happening?

This week we took our investigation further and learned about the FLOW of electricity around a CIRCUIT and the presence of ELECTRONS in our circuits. We even made a human representation of a circuit to demonstrate how quickly electricity gets to the various components.

Our cell sent power through the electrons in the wire to make our buzzer buzz!

Finally, we set up our circuits again and experimented with using extra components to discover whether we could light a bulb and run a motor or buzz a buzzer at the same time.
