Actually, we started by investigating whether water conducts electricity using a low voltage circuit. It does and we also discovered that adding salt made the water more conductive.

We then discussed the dangers of water and electricity, what happens to our heart if we are electrocuted and how doctors might be able to restart your heart using electricity.

However, if we’re mostly made of water does that mean we can conduct electricity? Well, we had a safe way to test this question with a human circuit…

…and yes, Year 4 can conduct electricity.

*Do not experiment turning yourself into a circuit – we knew what we were doing with safe equipment!
