Measuring Matter Part 2
Matter is anything that takes up space. We can measure matter by its volume or its mass. We can also measure it by its temperature or its density. Volume measures how much space something takes up. A bed takes up more space than a nightstand. Mass measures how much matter is in an object. A metal trophy has more mass than a stuffed toy. Temperature measures how hot or cold something is. Soup boiling on the stove is hot. Ice cream in the freezer is cold. Density measures how closely packed matter is. A block of concrete is more closely packed than a block of Styrofoam. Matter floats when it is less dense than the material around it. Oil is less dense than water, so oil floats in water.
