| Question | Answer |
|---|---|
| Grouping objects by their similarities (how they are the same). | Classify |
| Can be observed using the senses. | Physical Property |
| The amount of space that matter takes up. | Volume |
| The temperature and which matter changes from a solid to a liquid (0 degrees Celsius) | Melting Point |
| The temperature at which matter changes from a liquid to a gas (100 degrees Celsius). | Boiling Point |
| The pull of gravity on an object (can change). | Weight |
| Has mass and takes up space. | Matter |
| The amount of matter in an oject (doesn't change). | Mass |
| How tightly packed the matter in an object is cotton ball-loosely packed = low density, brass cute - tightly packed = higher density. | Density/Dense |
| Whether a substance is a solid, a liquid, or a gas. | State of Matter |
| A combination of two or more things | Mixture |
| A mixture in which one substance dissolves into another substance | Solution |
| Liquid turns into gas, leaves behind any dissolved substance. | Evaporation/Evaporate |
| Melts. The particles become smaller. | Dissolve |
| When a metal object is attracted to a magnet. | Magnetism |
| Ability of a substance to dissolve. | Solubility |
| When matter changes from a liquid to a solid (0 degrees Celsius) | Freezing Point |
