Energy and Conversions

Description:

Students will compare and contrast various types of energy. Students will demonstrate an understanding about the Law of Conservation of Energy through energy transformations within a closed system. 

Be sure to do everything below and you will do fine.

These are the “S” in WSQ. You must have them under your video notes completed by the due date on the Unit Plan.

Note: 8th grade, you will only do part 1 for Types of Energy WSQ

Part 1:



Part 2: This is for Energy Transformations

1. Look at the picture of the pole-vaulter below. Trace the energy conversions involved in this event, beginning with the pole-vaulter’s breakfast of an orange-banana smoothie.

2.

Look at the illustration below, and answer the questions that follow.

a. What is the skier’s gravitational potential energy at point A?

b. What is the skier’s gravitational potential energy at point B?

c. What is the skier’s kinetic energy at point B?

(Hint: mechanical energy = potential energy + kinetic energy)

Use the diagram below to answer the following questions.

3. At which point(s) does the pendulum have the most potential energy?

4. At which point(s) does the pendulum have the most kinetic energy?

5. How does temperature relate to kinetic energy?

6. Alex is waiting for his little brother to get home from school so he can pummel him with a
snowball. He is hiding on top of the roof that is 18 meters high. His snowball weighs 2.7 g.
(Hint:notice the units). What is the potential energy of the snowball?

HOT Question

Question about your Notes: write your question following the guidelines below:
Question- asking Higher Order Thinking (HOT) questions; use the following as your guide:
1. A question that you are still confused about (be specific, include which part of the video, etc)
2. A question that connects the videos together (i.e. asking about the relationship between the content)
3. A question you think you know the answer to, but you want to challenge your classmates with
