| What's the Matter | ||
| #1 | States of matter | solids, liquids, gases |
| #2 | This state of matter is usually invisible | gas |
| #3 | These molecules are packed tightly together and can hardly move | solid |
| #4 | Molecules move around quickly in this matter | gas |
| #5 | Matter that forms the shape of the container it is in | liquid |
| Change in Matter | ||
| #1 | The change in a state of matter from a liquid to a solid | freezing |
| #2 | Change in a state of matter from a liquid to a gas | evaporation |
| #3 | You can change the state of matter by either adding or subtracting this | heat |
| #4 | The temperature at which a given substance will change from a liquid into a gas is the ,...point | boiling |
| #5 | The change in a state of matter from a gas to a liquid | condensation |
| Small Particles of Matter | ||
| #1 | Size of molecules | tiny or microscopic |
| #2 | Small particles in a liquid that are not so tightly packed | molecules |
| #3 | A scientific tool used to see the tiny molecules in matter | microscope |
| #4 | The distance the molecules in a gas is, compared in a liquid | farther apart |
| #5 | Basic building blocks of matter | atoms |
| Moving Matter | ||
| #1 | Change in a state of matter from a solid to a liquid | melting |
| #2 | When adding heat to matter, the atoms will begin to move | faster |
| #3 | When you cool matter, the atoms will move | slower |
| #4 | Molecules in a gas will fill up a container or | spread out or expand |
| #5 | Light and heat are both forms of | energy |
| Everything Matters | ||
| #1 | Liquids take the shape of its | container |
| #2 | Liquids flow and with the help of gravity they move what direction | downward |
| #3 | The gas that is exchanged for oxygen as a waste product | carbon dioxide |
| #4 | The organ that is most responsible for our breathing in oxygen | lungs |
| #5 | The degrees in celsius, water changes from a liquid state to a solid | zero |
