Write an explanation of what gravity is aimed at a child. Keep it to a single paragraph.

Gravity is an invisible force that keeps us all attached to the Earth. The more mass and size an object has the more it pulls smaller objects. Every time you jump and fall back down, that's gravity! It's like sticking a magnet to your fridge but you're the magnet and the Earth is the fridge. Even the planets are affected. You can't see it, you can't feel it, and you certainly can't touch it but gravity is always there for you. Here is a fun lesson for you to try at home. Toss a baseball and a rock in the air and see which falls faster. You may be surprised that they fall at the same rate. That's because gravity is constant! Isn't science great?
