Atoms
Look around you; what do you see? Everything- and I do mean everything- you see is made up of matter. Matter is the "stuff" that makes up everything. Matter is anything that has mass and takes up space.
Mass is the measure of how much material makes up the object. Mass is measured in grams. A nickel has the mass of about one gram. Mass is related to how much something weighs. But mass and weight are not the same things.
Matter has volume. This is just another way of saying that matter takes up space. Volume is a measure of how much space something takes up. Volume is measured in liters.
Even some things you can't see are matter. Air is matter. You can't see air, but you can see things that air moves. Blow on a piece of paper. Watch a tree outside. You will see the paper move and will probably be able to see the leaves blowing on the tree. Moving air caused them to move. You can even touch air. Blow up a balloon. Poke the balloon with your finger. You can feel that something is inside the balloon.
Things like dreams or ideas are not matter. They are not made of any "stuff." They do not take up space. You can't touch an idea or a dream.
