| Matter | is all the stuff in the universe. |
| Matter is something that has | mass and volume. |
| Matter can exist as a | solid, liquid or gas. |
| A solid is a | substance that has a definite volume and holds its own shape. |
| A liquid is | matter that has a definite volume but no definite shape, and it takes the shape of its container. |
| A gas has | no definite shape or volume. |
| Physical change is the | change of the form of the matter, but does not change its identity (like ice melting). |
| Water is still water whether it's frozen into ice, | melted into liquid or evaporated into water vapor. |
| When you describe an object you are usually describing its | physical properties. |
| Color, size, roughness texture, hardness etc. are all | physical properties. |
| If you tear a piece of paper into pieces, | you change some of those physical properties. |
| If the change is a physical change, | the matter stays the same. |
| Another way to change matter is through a chemical change, | when one or more substances are changed to form a new substance. |
| Combining the ingredients for a cake and baking it, | creates a chemical change. |
| In a chemical change the physical properties will change too, | but the matter is different at the end of the process. |
| When rocket fuel is combined with oxygen, | a lot of energy is released. |
| The fuel is changed | into a number of different gases. |
| When you burn a piece of paper, | it's not paper. |
| It is ashes, | carbon dioxide, and a little steam. |
| During a chemical reaction you may observe a change in | color, heat. |
| Chemical reactions happen | all the time around us. |
| Every time a fire burns, wood and | oxygen are used up. |
| Smoke and | ash are produced. |
| When you eat, | your body chemically changes foods for growth and energy. |
| When you travel in a car, | gasoline and air are chemically changed. |
