When finished, login to your Earth Science class notebook (use the app). Make a copy of the “Heat Transfer Reading” in the content library and paste it into the “ISN” section of your notebook.

2. Heat Transfer
I can explain how heat is transferred through convection, conduction, and radiation.
I can give examples of how convection, conduction, and radiation occur every day in the real world.

3. 3 ways that heat can be transferred
The sun can heat things in 3 different ways.
Reading: Class notes

4. Heat Transfer Song

5. Conduction Read paragraphs #1-3 aloud Highlight definition conduction
Look at examples listed below. Which examples would show conduction?

6. Conduction Heat is transferred through direct contact (touch).
Heat travels from the warmer object to the cooler object
Examples: touching a stove and being burned, ice cooling down in your hand

7. Convection Read paragraphs #4 aloud Highlight definition convection
Look at examples listed below. Which examples would show convection?

8. Convection
Heat transfer through liquids or gases as particle circulate (rise and fall).
Warmer areas of a liquid or gas rise (less dense) and then sink down when they get colder (more dense).
Creates a circle, because of density differences
Example: convection currents, water boiling in circles in a pot, greenhouse

9. Radiation Read paragraphs #5 aloud Highlight definition radiation
Look at examples listed below. Which examples would show radiation?

10. Radiation Heat is transferred through space in the form of waves.
Examples: Sun rays, a campfire, an open oven door, heat from a light bulb

11. Check for Understanding: Question
In your notebooks answer the following question:
Where in this picture do you see radiation?
Where do you see convection?
Where do you see conduction?

12. Check for Understanding: Answer

13. Heat Transfer Practice
Directions: For each picture, show the correct sign when I count to 3. Do not put up sign before I count!
Convection: Hands in Shape of Circle (shape of convection movement)
Conduction: Hand to ear (directly touching ear)
Radiation: Hands in front (as if feeling heat from stove/campfire)

14. Example #1
How the inside of a greenhouse works.

15. Example #2
A pan sitting on a hot burner.

16. Example #3
Touching a metal spoon that is sitting in a pot of hot soup

17. Example #4
A person placing their cold hands over a warm fire

18. Example #5
Using a heating blanket to get warm

19. Example #6
Macaroni rising and falling in a pot of boiling water

20. Example #7
A person placing their hand over a hot burner

21. Example #8
Putting your wet shoes on a floor vent to dry them faster

Comic Strip: Due Tuesday

23. Heat Transfer Lab (5 min. each station)
At each station, observe what is happening by answering the questions.
Station 1: Beads
Observe what is happening to the beads in the beaker.
Station 2: Rub Hands together
Rub hands together for about 1 min, then put hands on face. Observe what is happening to the temperature of your face.
Station 3: Heat Lamp
Use the thermometers in each beaker to observe the temperature of the water with the lamp and the temperature of the water without the heat lamp.

24. Heat Transfer Lab
Based on your observations, classify each type of heat transfer and record the definition using your tree diagram.
Then, complete the Heat Transfer Classification (group) at the bottom of the lab and the “Popcorn Writing Prompt” on the back
If finished, work on your comic strip.

25. After Lab: Label Complete Heat Transfer Writing Prompt & Diagram
Heat Transfer Writing Prompt & Diagram: Draw and label three pictures showing how popcorn could be popped using each type of heat transfer (there should be a total of 3 pictures). Then describe underneath how it would show that particular type of heat transfer.
