1. Earth’s Energy

2. What is energy? Energy comes in many forms? In your Journal write all the different types of energy. Where can you find them?

3. The Law of Conservation of Energy Energy can not be created or destroyed! Hmmm… Let’s think about that.

4. Examples Driving a car Where does the energy come from? Where does it go when I stop?

5. Examples What about food? If I eat a peanut butter and jelly sandwich for lunch, where does the energy come from and where does it go?

6. What about the Earth? The Earth has tons of energy moving through it everday, But where did it come from?

7. The Solar Nebula Theory Image in this…. All of the energy in the world came from something as small as a tennis ball???

8. The Solar Nebula Theory What is matter? Something that takes up space. Does an elephant have a lot of matter?

9. The Solar Nebula Theory What about ten elephants?

10. The Solar Nebula Theory What about a page full of elephants?

11. The Solar Nebula Theory All of the matter in the whole universe came from something the size of a tennis ball??

12. That is what the solar nebula theory says. So let’s learn more. On a sheet of paper write Solar nebula theory at the top then underneath write evidence. The Solar Nebula Theory

13. So what is a Theory? Do you agree or disagree with this theory? Why?

14. Where does all this energy come from? The Sun!

15. Where does all this energy come from? Radiating solar energy heats the earth unevenly, creating air movements in the atmosphere. Therefore, the sun drives the winds, ocean currents and the water cycle.

16. Where does all this energy come from? Sunlight energy is used by plants to create chemical energy through a process called photosynthesis, and this supports the life and growth of plants.

17. Where does all this energy come from? In addition, dead plant material decays, and over millions of years is converted into fossil fuels (oil, coal, etc.).

18. Remember… Don’t forget though that energy can not be created or destroyed. Sometimes though this cycle of energy can not be recaptured. This is called an energy sink.

19. Energy Sink An energy sink is anything that collects a significant quantity of energy that is either lost or not considered transferable in the system under study. Sources and sinks have to be included in an energy budget when accounting for the energy flowing into and out of a system.
