| Question | Answer |
|---|---|
| Density | The amount of mass per unit of volume; how heavy something is compared to its size. A physical property which is determined by dividing the mass of an object by its volume. |
| Graduated Cylinder | A piece of laboratory equipment used to accurately measure volume. |
| Linear | In measurements, a straight line; distance. The basic SI unit is meter (m) and can be measured with a ruler. |
| Mass | The amount of matter in an object. Kilogram (kg) is the basic SI unit of mass. It is measured with a balance. |

| Temperature | A measure of the average kinetic energy of atoms in a substance; a measure of how fast the atoms are moving. It is measured with a thermometer in degrees on the Fahrenheit, Celsius, or Kelvin. |
| Triple-beam balance | A piece of laboratory equipment that is used to accurately measure mass. |
| Volume | The amount of space an object takes up. Liter (L) is the basic SI unit. |
| Weight | The force of gravity acting on an object. Newton (N) is the basic SI unit of weight. Weight can be measure with a scale. |
