1. ENERGY We’ve learned a little about energy sources (food, electricity)
Now let’s talk more about energy…

2. Energy Is All Around Us! Potential Energy – Stored Energy
All Energy Is Either…
Potential Energy – Stored Energy
Kinetic Energy – Energy of motion

3. Forms Of Energy
All Kinetic & Potential Energy can be separated into different forms, like…
Electrical
Chemical
Mechanical
Thermal

4. The Movement of Electrons
Electrical Energy
The Movement of Electrons
Light Bulb Circuit
Remember learning about the atom? What part of this atom are the electrons?
Discuss switches, movement of electrons. The movement of electrons through a wire is called “current”
Another word for Electrical Energy = Electricity

5. Electrical Energy is… Kinetic Energy? or Potential Energy?
Kinetic Energy! Potential Energy
(Energy of motion)

6. Chemical Energy Energy stored in materials
Kinetic Energy? or Potential Energy?
Batteries
Food
Coal
Petroleum
Kinetic Energy Potential Energy!
(Stored energy)

7. Mechanical Energy The movement of objects from one position to another
Kinetic Energy? or Potential Energy?
Peddling a bicycle
Moving fountain
Video is of Canal City Musical Water Fountain Display in Japan
Kinetic Energy! Potential Energy
(Energy of motion)

8. Thermal Energy Heat, caused by the movement of small substances
Kinetic Energy? or Potential Energy?
Heating a room
Discuss switches, movement of electrons.
Kinetic Energy! Potential Energy
(Energy of motion)

9. Activity – Potential & Kinetic Energy
Dominoes
Students build domino line and make them fall.

10. ENERGY cannot be created. ENERGY cannot be destroyed.
Can you think of ways energy has been transformed?

11. Let’s see what we CAN do with it….
SO....
We have ALL this energy…..
Let’s see what we CAN do with it….

12. We can STORE it. What does it mean to store something?
Can you see energy?
How can you store something you can’t see?

13. Storage means?….
Storage =
A place to hold
something

14. To prevent wasting extra energy that’s made
Why Store Energy?
For future use
To prevent wasting extra energy that’s made
If you have too much energy in, things blow up, or the energy needs to be released and wasted.
If you have too little energy, there will be black outs.

15. What is the most common way to store electrical energy?
What kind of energy is in batteries (chemical, mechanical or thermal)?
Every single portable electronic device has batteries in it.
Batteries come in all different shapes and sizes – the one in your car is much bigger than the one in your cell phone.
All batteries have chemicals in them… let’s take a look inside a battery…
Two or more chemicals are stored in each battery.
If the chemicals mix together, electrical current flows.
Every thing is made up of chemical bonds.
If you break the bonds (like by burning), you release energy.
Batteries!

16. Other Ways To Store Energy
Fuel
Fuel
Coal
Battery
capacitor
Coal
Food

17. Demo – Is Energy Stored? Balloon
This is actually setting up for the energy transformation activity.
Procedure:
Partially fill one cup w/ water
Set filled cup on desk and ask class if this is stored energy.
Blow up balloon and ask class where the stored energy is.

18. ENERGY cannot be created. ENERGY cannot be destroyed.
Can you think of ways energy has been transformed?

19. We can change it, or TRANSFORM it.
We can STORE it.
We can change it, or TRANSFORM it.

20. Transformation = The act of changing from one form to another
Transformation means?….
Transformation =
The act of changing
from one form to
another

21. Energy Transformation
Potential
Energy
Kinetic
Energy
Ask for students to think of how you can transform energy from potential energy to kinetic energy. Show demos.
Balloon
Spring
Rubber band
Newton’s cradle – when you do this, introduce the concept of the hypothesis.
Then ask them how you can transform kinetic energy into potential energy.
Pouring water
We’ll study more about this later… (bring it up again on wind day, ocean day, etc.)

22. Forms Of Energy
All Kinetic & Potential Energy can be separated into different forms, like…
Electrical
Chemical
Mechanical
Thermal

23. Energy Transformation
Mechanical Energy
Thermal Energy

24. Water Heater
How many of you use generators at home? What does a generator do? (Generate or produce electricity.)
This type of generator uses gasoline to run – it transforms the potential energy of the gasoline into electrical energy. But we’re trying to move away from using fossil fuels, so I’m going to show you different types of generators that don’t require fossil fuels.
Large generators at Hoover Dam.

We can STORE it.
We can TRANSFORM it.
We send it somewhere, or TRANSMIT it.

31. something from one place to another
Transmission means?….
Transmission =
The act of sending
something from one place to another

32. How Do We Transmit Energy?
Today we use Power lines

33. Energy Transmission Power lines
