1. Science starter Think about the convection demonstration yesterday. Answer the following question. How does the mixing of the hot and cold waters relate to cooking noodles?

2. Science starter What is one example of conduction? One example of convection? One example of radiation?

3. Science starter The type of transfer shown by Scenario B is known as conduction. In this situation, the man’s hand gets hot, because [6-5.5] a.he is holding his hand close to the fire. b.he is holding on to the handle of the pot. c.the handle of the pot is acting as an insulator. d.The water is boiling and blowing steam onto his hand.

4. agenda Science starter Standard/objective/eq Finish heat transfer demo Heat transfer notes Heat transfer classwork/hw

5. Heat transfer 6-5.5

6. conduction Transfer of heat between touching objects Heating of a solid Conductor- material that allows transfer of heat Insulator- material that does not allow easy transfer of heat Conductors heat faster than insulators Heat moves from hotter object to cooler object

7. conduction Examples?? Burger touching a grill Pan touching the stove Needle IN the flame Touching a light bulb (one that’s on)

8. convection Transfer of heat from gas or liquid to other objects Particles with more energy carry it with them when they move Heat moves from hotter area to cooler area Cause of currents in wind and water

9. convection Examples??

10. radiation Transfer of heat through empty space Heat is absorbed by cooler object Heat moves from hotter area to cooler area

11. radiation Examples?? The sun! Bonfire Heater
