Matter!
Matter is everything around you. Atoms and molecules are all composed of matter. Matter is anything that has mass and takes up space. It is actually the amount of stuff in an object.
Even though matter can be found all over the Universe, you will only find it in a few forms on Earth. We cover five states of matter here. There are many other states of matter that exist in extreme environments.
Scientists will probably discover more states as we continue to explore the Universe.
Fun Facts about States of Matter
Liquids, like water, oil and soda, shift to fit inside the container they’re in. If you look at them under a microscope, you’ll see that they have particles that are close together, but have no rhyme or reason. The molecules move around.
Gases, including air, steam and helium, flow free. You can easily put your hand through them. Gases shift to fit their container and can even fill it. Their molecules are spaced far apart and wiggle and jiggle. 
Solids, like your desk, your backpack and your pants, are firm and
stable. Their molecules are grouped together in organized patterns. The molecules might vibrate slightly, but they don’t move around.
