The Sun produces a lot of energy called solar energy. Australia gets 20,000 times more energy from the Sun each day than we do from oil, gas and coal. This solar energy will continue for as long as the Sun lives, which is another 5 billion years. Solar panels are made of solar cells, which is the p...

If you were lucky enough to go to the moon, you’d be able to jump six times as high there as you can here on Earth. Try it: jump up and imagine you’re on the moon. Six times further up you’d go (better not look down). How does that work? Well, it’s all to do with gravity, that mysterious fo...
