1. Bellwork Comp. Book page 24 – ENERGY
Discuss with your neighbor the relationship between work and energy.

2. INTRODUCTION to ENERGY
Distinguish among gravitational potential energy, elastic potential energy, and chemical potential energy.
SPI
Interpret the relationship between potential and kinetic energy.

3. INTRODUCTION to ENERGY
Learning Goal:
I can identify potential and kinetic energy and their differences.
Success Criteria:
In your own words, can you describe potential and kinetic energy?
Can you analyze an object and determine the highest and lowest points of potential and kinetic?
Can you identify energy scenarios as potential or kinetic?

4. What is Energy? Energy is the ability to do work.
Work is the transfer of energy.

5. What are the Two Types of Energy?
Kinetic Energy - energy of being in motion.
Potential Energy - the energy of shape or position (stored energy.)

7. Losing potential and gaining kinetic Mostly potential

Losing kinetic and gaining potential

8. Examples of Kinetic Energy
Cheetah Running
Dolphins Jumping

9. Examples of Potential Energy

10. POTENTIAL
KINETIC
Write the number.

11. Potential vs. Kinetic Charades
With your table, come up with a scenario to act out for potential energy or kinetic energy.

12. Rubber Band Lab With a partner…
Take turns being the shooter and the measurer.
Stand behind the line.
Shoot the rubber band off the end of the popsicle stick.
Measure how far you are pulling the rubber band back before you let go.
Measure how far the rubber band traveled from the line.
Record the data.
Ask you are completing this lab, think…
POTENTIAL ENERGY?
KINETIC ENERGY?
