1. Electricity Chorus Electricity, Yes it’s a form of energy, That’s flowing in a circuit round and round. Electricity, It’s something that you’ll never see Unless a bolt of lightning hits the ground! 1. Power stations everywhere Use lots of cables in the air, For sending electricity To all our homes and factories. Changing gas and oil or coal To electricity’s the goal While solar, wave and wind machines All help to keep our planet green. Chorus 2. Get a battery add a switch, Connect the wires without a hitch To make a circuit let it flow And you will see a light bulb glow. Many things we use each day All need this power in some way Like fridges, tablets, heaters too, Your mobile phone, toys and Freeview.

2. WORDS TO REMEMBER: ELECTRICITY ATOM ELECTRON PROTON NEUTRONS CONDUCTORS INSULATORS
