To wrap up, we’ll be working on a fun activity…

1) Think of your favorite song.
2) Find 5 points of frequencies from the song.
3) Find 5 wavelengths from your song.
4) Remix a segment of your song to change 5 points of frequencies from the song.
5) While you’re remixing, change 5 wavelengths of your song.

Post the finished remix or clip on your blog.

You can present all of this either analog (with paper, posters etc) or digitally (video, podcast on a blog post etc).

Enjoy!

3. How are conductors and insulators different?
4. Would a copper pipe work better as a conductor or insulator? Why do you think so?
5. Suppose you are camping on a mountain, and the air temperature is very cold. How would you keep warm? Would you build a fire or set up a tent? Write an explanation for each action you would take. Tell whether conduction, convection or radiation is involved with each heat transfer.

Objective 4: Thermal Energy and Matter

1. What causes matter to change state?
2. What happens to a substance as thermal energy increases?
3. Why does the temperature of matter remain the same while the matter changes state?

5. Why should you poke holes in a potato before baking it?

Objective 5: Using Heat

1. How do heat engines use thermal energy?
2. How are internal combustion engines different from external combustion engines? How are they similar?
3. Why do you think modern cars use internal rather than external combustion engines?
4. What changes of state occur in the refrigerant of a refrigerator?
5. If the compressor in a refrigerator stopped working, how would its failure affect the heat transfer cycle?

Objective 6: In Hot Water Lab

Goal: Build a containter for a 355 mL aluminum can that keeps water hot.

Your container must:
- minimize the loss of thermal energy from the hot water
- be built from materials approved by Mr H
- have insulation no thicker than 3 cm.
- not use electricity or heating chemicals (hand warmers, etc)

With a group of classmates or yourself, brainstorm different materials that prevent heat loss. Write a plan for how you will test these materials. Include a list of things you will test when doing your tests. Test out your ideas to determine the best insulating materials. Keep a log of your results in your lab notebook. Then bring the device to class!
