| A | B |
| conduction | the movement of heat within a solid or from one solid to another |
| conductor | any material that allows heat to move through it easily |
| examples of conductors | metals, gold, aluminum |
| convection | the way in which heat moves through liquids and gases |
| friction | a force that occurs when one object rubs against another object |
| heat | the flow of thermal energy from warmer objects to cooler objects (when you are cold you want to stay still) |
| insulation | any material that does not allow heat to pass through it easily |
| examples of good insulators | plastic, porcelain |
| radiation | the movement of energy by waves |
| how we get the energy from the sun | radiation |
| solar energy | energy from the sun |
| temperature | a measure of how hot or cold something is |
| thermal energy | the energy of moving particles in matter |
| thermometer | a tool that is used to measure temperature |
