1. Grab one of each sheet. I will tell you where to tape them in, in un momento
Copy down HW

2. Forms of Energy
Physical Science

3. Energy is the ability to do
Energy is measured in
work.
joules

4. Forms of Energy
Energy appears in many forms. There are five main forms of energy.
Mechanical
Heat
Chemical
Electromagnetic
Nuclear
See if the students can name the forms first – then click through…

5. Mechanical Energy Energy of motion. Water in a waterfall Wind
Examples:
Water in a waterfall
Wind
Moving vehicles
Sound
Other examples from the class???

6. Mechanical Energy
When you kick a football, you give mechanical energy to the football to make it move.

7. Mechanical Energy
When you throw a bowling ball, you give it energy. When that bowling ball hits the pins, some of the energy is transferred to the pins.

8. Heat Energy/Thermal The internal motion of atoms.
The faster the molecules move, the more heat energy is produced.
Example:
Friction
Discuss common kinds of friction students may be familiar with – hands rubbing together – tires- engine parts Candles – One lit candle in a car can increase the temp 2 degrees – if you are in a snow bank and cannot run the heater…

9. Chemical Energy
Energy that exists in the bonds that hold atoms together.
When bonds are broken, chemical energy is released.
Remind students of video of the sodium metal in water – produced fire – Chemical Change…

10. Energy that exists in the bonds that hold atoms together.
When bonds are broken, chemical energy is released.

11. Chemical Energy
Examples:
Digesting food…bonds are broken to release energy for your body to store and use.

12. Fuel and food are forms of stored chemical energy.

13. Electromagnetic/Light/Electric /Radiant Energy
Moving electric charges.
Explain the picture with the xrays…

14. Examples:
Power lines carry electricity
Electric motors are driven by electromagnetic energy
Light is the form of energy (X-rays, radio waves, etc.)

15. Nuclear Energy
What is the difference between fission and fusion? Which one is/was being used in this state?

16. When the nucleus of an atom splits, nuclear energy is released.
Nuclear energy is the most concentrated form of energy.

17. The Law of Conservation of Energy
Energy can be neither created nor destroyed by, it can only be converted from one form to another.

18. All forms of energy can be converted into other forms.
Energy conversions
All forms of energy can be converted into other forms.
Green plants convert the sun’s energy (electromagnetic) into starches and sugars (chemical energy).

19. Other energy conversions
In an electric motor, electromagnetic energy is converted to mechanical energy.
In a battery, chemical energy is converted into electromagnetic energy.

20. Energy Conversions
In an automobile engine, fuel is burned to convert chemical energy into heat energy. The heat energy is then changed into mechanical energy.

21. Use the video to add to your notes Sound is mechanical

Use the video to add to your notes
Sound is mechanical
Radiant is electromagnetic
