1. Intro to Heat And Energy Transfer

2. Heat Heat is kinetic energy in a substance. Heat is the motion of the molecules in a substance, not the motion of the substance. Energy that flows between two objects because of a difference in temperature. For example, a metal spoon in hot water.

3. Measuring Heat Celsius Freezing : 0 degrees Boiling : 100 degrees Fahrenheit Freezing : 32 degrees Boiling : 212 degrees

4. Heat Movement Molecules move from places of higher temperatures to places with lower temperatures

5. Thermal Equilibrium Molecules move from warm to cold until they reach a balanced temperature This balance is called thermal equilibrium.

6. Insulators & Conductors 6 th Grade Science

7. Vocabulary Insulator an object that reduces the transfer of heat Conductor an object that easily allows the transfer of energy

8. Expansion & Contraction

9. Vocabulary Expansion as molecules in a solid, liquid or gas are heated they spread out as they move around quickly and cause objects to become larger (expand) Heating = Bigger Contraction as molecules in a solid, liquid or gas are cooled they move closer together and cause objects to shrink (contract) Cooling = Smaller

10. Vocabulary Solid particles vibrate in one place Liquid particles spin and move closely togetherGas particles spin and move fast and far away from each other

11. Heat Transfer

12. Vocabulary Conduction  the transfer of heat by direct contact between solids Convection Transfer of heat in liquids & gases Transfer of heat in liquids & gases Heat rises Heat risesRadiation Transfer of heat in empty space w/o any particles Transfer of heat in empty space w/o any particles

13. Examples Conduction A pot heating on a stove A metal spoon in boiling water Convection Boiling water Boiling water Heating a home Heating a homeRadiation Sun’s rays heating a car Sun’s rays heating a car Sun’s rays heating Earth Sun’s rays heating Earth Heat from Heat from a fire
