1. Can I recognize different types of energy transformations?
Essential Question:
Can I recognize different types of energy transformations?

2. Success Criteria: I can…
Explain Conversion
Identify energy converting forms

3. What is an Energy Conversion?
A change from one form of energy into another is called an energy conversion.
What type of energy do you have when you are jumping on a trampoline?

4. List the different types and forms of energy involved in jumping on a trampoline:
Kinetic, chemical, sound, thermal, electrical
In the air
Kinetic, potential, thermal
Trampoline stretching
Kinetic, potential, thermal, electrical, sound

5. Roller Coasters…
At what point does a roller coaster have the greatest potential energy?
At what point does a roller coaster have the greatest kinetic energy?

6. Energy Conversions: Chemical Energy
Chemical energy in food is converted into kinetic energy when you are active and thermal energy to maintain body temperature.

7. Energy Conversions: Chemical Energy
With photosynthesis, light energy (from the sun) is converted into chemical energy (sugars inside the plant).

8. Energy Conversions: Electrical Energy
Alarm Clock
Battery
Lightbulb
Blender
Electrical Energy 
Light Energy, Sound Energy, Kinetic Energy
Chemical Energy 
Electrical Energy & Thermal Energy
Light Energy & Thermal Energy
Kinetic Energy & Sound Energy

9. Energy & Machines
Give an example of a machine that converts energy (Discuss with a neighbor).
Bicycle:

10. Energy & Machines
Chemical energy in your body is converted into kinetic energy when your muscles contract and relax.40
Your legs transfer this kinetic energy to the pedals, pushing them around in a circle.
The pedals transfer kinetic energy to the gear wheel, which transfers kinetic energy to the chain.
The chain moves and transfers energy to the back wheel, which gets you moving!

11. Other Machines that Convert Energy…
Electric motor
Microphone
Toaster
Windmill
Dishwasher
Doorbell
Lawn mower
Gas heater
Clock
Telephone

12. Name the six forms of energy and give an example for each.
