2. Objective #2: Conservation of Energy

How is energy conservation like spending money?

a. I can analyze what is meant when it is said that “energy is conserved.”
b. I can identify whether an energy transfer or transformation is taking place.
Vocabulary: energy transformation, energy transfer `

Illinois Assessment Frameworks: 12.11.67

Now that we know what energy is, we need to talk about how energy, like mass and momentum, is conserved. Let's start first with the Voicethread below! Watch it, and take notes as instructed during the video. MAKE SURE YOU SHOW MRS. E YOUR NOTES WHEN YOU'RE FINISHED!

Have you shown Mrs. E your notes yet and fixed whatever needs fixing? Fantastic! Move on to the activity below, having your notes out and at the ready.

1. Open this document. Download it, and then upload it into Crocodoc

2. Scroll down to page 135, the page that has "Conservation of Energy" at the top.

3. Highlight the following:
  •     examples of energy conservation
  •     any phrases that could be used to help you define what is meant when it is said that "energy is conserved."

4. In a blog post, answer the I can statement (2a) and BOTH essential questions (How are kinetic energy and potential energy connected? and How is energy conservation like spending money?) in paragraph form.

Objective #2b: I can identify whether an energy transfer or energy transformation is taking place.

Watch the video first below, and take notes as instructed. Be sure to show your notes to Mrs. E when you're finished!

Trouble seeing the video? Click here to watch it.

1. Read the information in this Google Doc. Make a copy, and then fill in any questions that you are asked.

2. At the bottom of the Google Doc, summarize TWO differences between energy transfers and energy transformations.

3. Check out the diagram below:

4. With someone else at your table, discuss what's happening at each arrow--is it an energy transfer, or transformation? Also discuss why you made the choices that you did.

5. There are two situations below. For each one, draw out the steps like the picture above, explaining the energy involved in each stage, and stating whether it is an energy transformation of transfer. Do this in a Google Doc or using a drawing tool of your choice, (You may also want to check out Google Drawings.)

You must have at least 4 steps for each situation!

Situation #1: Mrs. E driving her car to the store and back.
Situation #2: You getting on the bus and coming to school and getting ready for first period.
