Maddie is ready to go puddle jumping, she’s got her wellies and her mac, but discovers all the puddles have gone! We find out what happens to the puddles when the rain stops, and the sun comes back -It’s called evaporation. Maddie takes us on a journey into the clouds and learns when water heats up, the liquid water turns into a gas called water vapour. We see that water vapour is light, so it rises up high into the sky – taller than a skyscraper!
