  1. Heat Transfer How is energy transfer different than energy transformation?

  2. Key Topic Heat Transfer The FRAME Routine is about… Main idea Main idea Main idea What is it? So What? (What’s important to understand about this?) How heat moves from place to place. 3 Methods: Conduction Convection Radiation What is it? What is it? Example: Example: Example: Example: Example: Example: Example: Example: Example: .

  3. Brain POP: Heat-do activity page As you watch the brain pop, think about…….. -What is the difference between heat and temperature? -Can an iceberg have as much heat energy as a pot of boiling water? -How does heat move? -What does adding heat do to the molecular movement within a material?

  4. Conduction • Transfer of heat energy by direct contact Do: with your groups, brainstorm and record 3 examples of conduction-be prepared to share one example with the class

  5. Convection • Transfer of heat energy by movement of particles Question: Where have we discussed convection previously?

  6. Convection Examples: in the layers of the Earth

  7. Convection Examples: in the atmosphere

  8. Convection Examples: in the oceans

  9. Radiation • Transfer of heat energy by electromagnetic waves • What are some types of electromagnetic waves?

  10. Radiation Examples:

  11. Radiation Examples: Our Earth is heated by the sun through radiation -we couldn’t survive without it!

  12. So What????? • Heat moves from warmer areas to cooler areas • Heat can cause materials to change phase or state • Heat likes to remain uniform
