1. Today’s Agenda…11/10 Bellringer: What is the difference between kinetic and potential energy? Give an example of an object with each. Discuss worksheet – Heat on the Move Notes on Heat Transfer Homework: Worksheet

2. Heat on the Move Study Pack #6

3. Today’s goals… I can continue to describe how heat is transferred I can compare conduction, convection, and radiation.

4. Foldable Three folds

5. Heat Transfer Heat will move when there is a difference in temperatures Heat will move when there is a difference in temperatures Heat will ALWAYS move from the warmer object to the cooler one Heat will ALWAYS move from the warmer object to the cooler one Heat can be transferred (move) in three ways: Conduction Convection Radiation

6. Conduction Transfer of heat through collisions between atoms in a substance The kinetic energy of the substances is transferred Heat transfer my direct contact

7. Conduction Usually occurs in solids Examples: Burning your hand on a stove Feeling warm sand on your feet at the beach

8. Conduction Materials through which it is easy to transfer heat are called conductors Metals Materials that are poor conductors are called insulators Plastic

9. Convection Usually occurs in liquids and gases As particles warm, they spread out and become less dense These particles rise, while cooler, more dense particles fall This creates convection currents

10. Convection Examples Heating soup on a burner Heating your home

11. Radiation The transfer of energy by rays or waves No direct contact Examples: The sun warming the Earth

12. Activity!! Come up with one example of each type of heat transfer – draw an example of this on the front of your foldable We will share our examples at the end of class Try to come up with something we didn’t share in class!
