Kaupapa:
Identify and describe different forms of energy
Describe examples of simple energy transformation

3. What is “Energy”?

4. How does it work?

5. Energy Energy is what makes things ‘work’.
Examples: car, airplane, cellphone, computer, dog, human, etc.
Energy is measured in ______.
There are many different forms of energy.

16. Energy in different forms
Light energy
Heat energy
Sound energy
Radiation energy
Kinetic energy
Electrical potential energy
Nuclear potential energy
Chemical potential energy
Elastic potential energy
Gravitational potential energy

17. Potential Energy = “Stored” Energy
Example: Chemical potential energy is stored in fuel and food
Active Energy = “Observed” Energy
Example: Sound energy can be heard, light energy can be seen and heat energy can be felt.

18. Energy Transformations
