      I like the lightening bolts! How did you do that?!

      Electricity is the flow of electric charge. This is normally electrons moving through wires but it can be in other places such as the sky (lightening). You get positive (+) and negative (-) charge, electrons are negatively charge so they flow away from negatively charged things and towards positively charged things. You always need a change in charge to get the flow which causes electricity, that’s why it is important which way round a battery goes (and why they have a + and – on!)

      Electricity is a the flow of charged particles through a substance. This can be electrons or larger particle like an ion. Wherever there are charged particles which can move and areas of different charge creating a “potential” then you get electricity.

      So electricity comes in all sorts of places such as in the atmosphere, a lemon with copper and zinc pins stuck in it or even your own nerve cells!
