Matter is all around us. Matter is the air you are breathing. Matter is the computer you are reading from now. Matter is the stuff you touch and see. And it is more. Matter is defined as anything that hasmass and takes up space. Matter is found in 3 major states; solid, liquid and gas.
Solid:Matter that is composed of atoms packed tightly together are known as solids. You cannot walk through a solid wall. The matter is packed so tight that it prevents you from moving through it. Solids hold their shape at room temperature. The pencil that you left in the desk at school will still be the same shape when you return tomorrow.
Liquid:Liquids do not hold their shape at room temperature. There is space between the atoms of a liquid and they move slightly all of the time. This allows you to stick your finger into water and pull it back out, letting the water fill back in where your finger once was. But when walking through the water in the swimming pool, you have to push the water out of the way ‐ this means that you feel the heaviness of the water. Liquids flow or pour and can take on the shape of a container. If the liquid is poured into a wider or narrower container, the liquid will take on that new shape. Liquids are affected bygravity. If you pour only half a cup of milk, the top half of the container would have no milk. Liquids cannot be handed to another person well without the container. Imagine going into a restaurant and asking for lemonade. What if the waiter just put the lemonade into your hands ‐ no glass or cup? Could you lay the lemonade on the table to drink in a few minutes? Even water in a river or a lake has a container ‐ the banks, the bottom, the shore ‐ they form the container.
Gas: Gases not only do not hold their shape at room temperature, they don't even stay put. Gases are always moving. There is so much space between the atoms in gas that you can move around in them easily. When you walk from one side of the room to the other, you have walked through a bunch of gases that make up our air. You barely even know they are there. Gases will take on the shape of their container and can be compressed into a smaller space. Like when we compress air into a balloon ‐ it fills out the balloon shape. Gases will fill up the space too. You don't see only half of the balloon filled with air ‐ the air is not as influenced by gravity as a liquid or a solid would be.

CHANGING STATES. All matter exists as solids, liquids, or gases. ... Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid).
