There are three main types of matter. They are solid, liquid and gas. All though some people believe that there is a fourth type of matter called plasma. So let’s start with me telling you about a solid. A solid is some thing were the atoms stick together and don’t move around. They stay still and don’t move .  But it’s different When your taking about liquid because if you think about water it takes the shape of the thing that it is in. So if it is in a glass of water, the atoms in it are moving around a lot. Even when you just shake the water around you are moving  hunderds of thousands of atoms. But with gas, if you just give your freind a high five you are moving around thousand of atoms in the air.
