Matter Is...
Look at some different objects around you. You might see a desk, a pencil, and the girl who is sitting in front of you. Each of these objects is very different from the others. Yet all the objects are alike in some ways.
These objects are all alike because they all take up space. The pencil takes up only a small amount of space. The desk takes up more, and the girl probably takes up more space than the desk. The amount of space an object takes up is its volume.
All these objects are alike in another way. They all have mass. An object's mass is the measure of how much material makes up the object. You can find how much mass an object has using a balance. The units used to measure mass are usually grams or kilograms.
