1. ENERGY Bell ringer 1-30-2017 On the top of your notes, write down:
Where have you heard the word energy before?
What do you think it means

2. Standards and Objectives
GLE Compare and contrast the three forms of potential energy.
I can-SPI Distinguish among gravitational potential energy, elastic potential energy, and chemical potential energy.

3. Some examples would be- hitting a baseball
GLE Compare and contrast the three forms of potential energy.
So what is energy?
Energy is anything that can cause matter to change. It is the ability to do work.
Some examples would be-
hitting a baseball
holding a book above your head
digesting food
heating water
Tell your partner some examples of energy you see daily.
Be ready to discuss.

4. Potential Energy Mechanical Energy
GLE Compare and contrast the three forms of potential energy.
The main focus for today…
Mechanical Energy
…and not just mechanical energy, but we are going to take it one step further and focus on…
Potential Energy

5. Energy due to a object’s motion (kinetic) or position (potential).
GLE Compare and contrast the three forms of potential energy. But First, what is Mechanical Energy?
Energy due to a object’s motion (kinetic) or position (potential).
We will learn about kinetic energy tomorrow
The bowling ball has mechanical energy.
When the ball strikes the pins, mechanical energy is transferred to the pins!

6. GLE Compare and contrast the three forms of potential energy. Examples of Mechanical Energy

7. GLE 0607.10.1 Compare and contrast the three forms of potential energy. Now for the MAIN EVENT!!!!!!
Potential Energy- An object that has the potential to make something happen. (Stored energy)
Be ready to discuss…..
Using the rock from the video, explain potential vs. kinetic.

8. To Take it Further…. There are three types of potential energy.
Gravitational
Elastic
Chemical

9. Lets think of some examples….
GLE Compare and contrast the three forms of potential energy.
Gravitational Potential Energy
-Energy due to an object’s position in a gravitational field.
position-mass-height
Lets think of some examples….
Can you point out any examples in this room that might be an example of gravitational potential energy?

10. Lets think of some examples….
GLE Compare and contrast the three forms of potential energy.
Elastic Potential Energy
-Energy stored in an object.
(Compression and tension)
Examples-rubber band, bow and arrow, slinky
Lets think of some examples….
*Turn and talk with your partner about examples of elastic potential energy.
Be ready to discuss.

11. Be ready to discuss. Chemical Potential Energy
GLE Compare and contrast the three forms of potential energy.
Chemical Potential Energy
-Energy stored in chemicals.
Examples-battery, candle, firewood
*THINK-If firewood is considered to have chemical potential energy, what other….flammable…. objects might have chemical potential energy?
Be ready to discuss.

12. Lets determine which type of potential energy each item would be.
GLE Compare and contrast the three forms of potential energy.
Lets determine which type of potential energy each item would be.
Using your white boards, answer each number with
G-gravitational
C-chemical
E-elastic
Charcoal
Battery
Sling-shot
Girl standing at the edge of a high dive
Rubber band
Be ready to discuss your answers.

13. Let’s take it a little further….
How would we compare the three types of potential energy?
What makes them similar?
What makes them different?

14. When does potential energy turn in to kinetic energy?
GLE Compare and contrast the three forms of potential energy.
When does potential energy turn in to kinetic energy?
Let’s think of some examples of this
Compare potential to kinetic energy.

15. GLE 0607.10.1 Compare and contrast the three forms of potential energy.
Summarizer-
Using what you have learned today, answer the 5 question quiz and turn in to the purple basket.
