Properties of Matter
| Term | Definition |
|---|---|
| Physical Property | a property that can be observed, measured, or changed without changing what the object is made of |
| Measuring | developing and using appropriate units of measurement for length, area, mass, volume, time, weight and temperature |
| Matter | anything that has mass and takes up space |
| Mass | the amount of matter in an object |
| Meter | a metric unit to measure length (height from the floor to a doorknob) |
| Millimeter | a metric unit to measure length (1,000 mm = 1 m) (the width of a pencil lead) |
| Centimeter | a metric unit to measure length (100 cm = 1 m) (th e width of a little finger) |
| Decimeter | a metric unit to measure length (10 dm = 1 m) (length of a new crayon) |
| Kilometer | a metric unit to measure length (1,000 m = 1 km) (distance from school to the grocery store) |
| Gram | a metric unit to measure mass (mass of a large paper clip) |
| Kilogram | a metric unit to measure mass (1,000 g = 1 kg) (mass of a textbook) |
| Volume | amount of space that matter takes up |
| Capacity | the maximum volume of a container |
| Liter | a metric unit to measure volume (volume of liquid in half of a large soda bottle) |
| Milliliter | a metric unit to measure volume (1,000 mL = 1 L) (volume of liquid in 2-3 water drops |

| Magnetism | the pushing or pulling force between the poles of magnets |
| Sink | an object falls to the bottom in water |
| Float | an object sits on top of water |
| Solid | matter that has a definite shape and takes up a definite amount of space |
| Liquid | matter that takes the shape of its container and takes up a definite amount of space |
| Gas | matter that has no definite shape and takes up no definite amount of space |
| Temperature | the measure of the warmth or coldness of an object |
| Celsius | a metric unit to measure temperature |
| Evaporation | the process of changing a liquid into a gas |
| Condensation | the process of changing a gas into a liquid |
| Mixture | a combination of two or more different kinds of matter, each of which keeps its own physical properties |
| Solution | a mixture in which the particles of different kinds of matter are mixed evenly with each other |
| Dissolve | to make a solution of, such as salt in water |
| Solubility | a measure of the amount of a material that will dissolve in another material |
