Matter
Matter is all around us. Everything that you can touch, taste, smell, and see is made of matter. Anything that takes up space is called matter.
There are three states of matter: solid, liquid, and gas.
Solids
Solid matter has its own shape. This is because the tiny molecules that make up solids are very close together, and they do not move very much. Solid matter can be big, small, round, square, or any shape you can imagine. Ice, a cup, apples, paper, and windows are all solids. The shapes of solids do not change unless something makes them change. For example, you can cut solid paper or break a solid cup.
Liquids
Liquid matter does not have its own shape. The tiny molecules in liquids are not as close together as they are in solids, and they can move around more. Water, glue, milk, gasoline, and juice are all liquids. Liquid matter takes the shape of the container that it is in. For example, the shape of milk looks like the shape of the glass that you pour it in. Liquids can pour, drip, flow, and splash.
Gases
Gas matter, like liquid, does not have its own shape. The tiny molecules in gases are far apart, and they move a lot. Steam, exhaust from the car, oxygen, carbon dioxide, and helium are all gases. Gases spread out and fill up their container. For example, when someone blows up a balloon, the carbon dioxide in their breath spreads out inside the balloon to make the balloon get bigger.
Sometimes matter can change from one state to another if the matter is heated or cooled. For example, liquid water can turn into solid ice when cooled. Liquid water can also be turned into steam when heated.
