Chloe’s circuit conumdrum

In Science, Year 4 have been making electrical circuits and have discovered that all the components need to be connected together to complete the circuit and allow energy to flow. We have also learnt that we may add a switch to our circuit that allows us to break the circuit and turn electrical products off.
