HEAT TRANSFER HOW IS ENERGY TRANSFER DIFFERENT THAN ENERGY TRANSFORMATION?

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

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?

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

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

CONVECTION EXAMPLES: IN THE LAYERS OF THE EARTH

CONVECTION EXAMPLES: IN THE ATMOSPHERE

CONVECTION EXAMPLES: IN THE OCEANS

RADIATION • Transfer of heat energy by electromagnetic waves • What are some types of electromagnetic waves?

RADIATION Examples:

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

SO WHAT? ? ? • Heat moves from warmer areas to cooler areas • Heat can cause materials to change phase or state • Heat likes to remain uniform
