1. Homework answers (friends meet in front after roll is taken)
1. Heat/thermal energy = transfer of thermal energy
Heat ALWAYS moves from hot to cold.
Sources: Burning materials: (wood, candle wax)
Sun, Electricity

2. Please log into Socrative
Room name : CONGER
*Remember Last Name, First Name

3. Funky Friday Pick

4. APK
What does TRANSFER mean? Answer on your I-pad& flip it over so no one sees your answer.

5. EQ: How can heat energy be transferred?
Listen to me read the EQ.
Ladies, go to a gentleman and read the EQ.
Gentlemen. Go to a lady and read the EQ.
What are the 3 most important words in the EQ? (Socrative)
Class, what are we going to be able to answer today?

6. Lesson Importance: Why?
Why do you need to know how energy is transferred?
Think of an answer you have never used in class.
Think…..
Tell your group your answer.
Write your answer on your board.

7. Guided practice: Heat transfers by
Conduction
Convection
Radiation

8. Explain how is the heat being transferred? Picture 1

9. Explain how is the heat being transferred? Picture 2

10. Explain how is the heat being transferred? Picture 3

11. Explain how is the heat being transferred? Picture 4

12. Explain how is the heat being transferred? Picture 5

13. Conduction Objects that are touching (direct contact)
Transfer of heat energy occurs as particles collide (hit into each other)
** DUCT TAPE = TOUCHING

14. Give me an example of
Conduction (Socrative)

15. Some materials are better at conducting heat than others.
Poor conductors=insulators

16. Which spoon do you NOT want to pick up out of all of them?

17. EX: A metal spoon handle will get hot quicker than a plastic spoon
EX: A metal spoon handle will get hot quicker than a plastic spoon. Heat is conducted better through metal than plastic.

18. Explain how is the heat being transferred? Picture 6

19. Explain how is the heat being transferred? Picture 7

20. Convection
Heat energy moving in the heated substance itself (think about fluids, liquids, and gases)
Uneven heating causes air currents

21. EX: bathtub water oceans air

22. T A P P L E T I M E
What is convection?

23. Explain how is the heat being transferred? Picture 8

24. Explain how is the heat being transferred? Picture 9

25. Explain how is the heat being transferred? Picture 10

26. Radiation
Transfer of heat energy through space (NO particles are colliding or moving)

27. Heat always moves from HIGH temperature to LOW temperature.

28. 4 Corners: What is radiation?
Lady Bug) heat transfer through touch
Bumble Bee) heat transfer through space
Dragon Fly) heat transfer through liquid
Ant) heat not moving
Bumble Bee!!!
