| Definitions | ||
| #1 | Define conduction | Heat transfer through direct contact; objects must touch. |
| #2 | Define convection. | Heated energy through liquids and gases in currents. |
| #3 | Define radiation | Movement of energy through space as electromagnetic waves. |
| #4 | Define thermal energy | The energy of heat flowing from one object to another; heat energy |
| #5 | Define convection currents | Movement created by warmer air rising and cooler air sinking; movement from hot to cool |
| True or False | ||
| #1 | Heat passes from a cooler object to a hotter object. | False-Heat always passes from a hotter object to a cooler object. |

| Final Question | |
| Convection currents are produced by uneven heating. Explain the direction of air flow when warming your house in the winter. | When you heat your home, the air on the floor is heated and move farther apart. This layer of heat floats to the ceiling and the cooler air falls to the bottom. |
