1. THE ABILITY TO DO WORK

2. The combination of energy and matter make up the universe: Matter is substance, and energy is the mover of substance. Energy

3. The process of changing energy from one form to another. EXAMPLE: A windmill takes the kinetic energy of the wind and changes it into mechanical energy by turning the fan blades which can then be converted to electrical energy

4. The Law of Conservation of Energy Energy cannot be created or destroyed; it may be transformed (changed) from one form into another, but the total amount of energy never changes. However some HEAT energy is always “lost” during an energy transformation because it is not a closed system (heat leaves the system). The big picture… the total energy in the universe remains constant.

5. Conservation of Energy Energy is transformed… not destroyed!!

6. Copyright © Houghton Mifflin Harcourt Publishing Company What is an energy transformation? An energy transformation takes place when energy changes from one form into another form. Any form of energy can change into any other form of energy. Often one form of energy can change into two or more other forms.

7. Conservation of Energy Demonstration

8. Examples: Energy of FOOD can be transformed into energy to PLAY CHEMICAL energy from coal, oil, and natural gas can be transformed into HEAT energy (process of burning the fuel); the HEAT energy can be converted into KINETIC energy by gas turbines or into ELECTRICAL energy by generators. The sun gives the grass THERMAL energy. The grass uses it to grow and transform it to CHEMICAL energy during photosynthesis. Rabbits eat grass as an energy source. If you turn on the power switch, a light bulb will use the ELECTRIC power to transform it into LIGHT energy.

10. ENERGY DERIVED FROM THE SUN IN THE FORM OF SOLAR RADIATION

11. A CELL THAT CONVERTS SOLAR ENERGY INTO ELECTRICAL ENERGY

12. A CONCAVE MIRROR THAT CONCENTRATES THE RAYS OF THE SUN; CAN PRODUCE HIGH TEMPERATURES

13. BATTERIES THAT STORE SOLAR ENERGY AND CAN BE USED TO RUN APPLIANCES AT NIGHT OR WHEN THE SUN IS NOT SHINING.

14. POWER DERIVED FROM THE WIND AND USED FOR ELECTRICITY OR MECHANICAL POWER

15. A LARGE GROUP OF WIND-DRIVEN GENERATORS FOR ELECTRICITY SUPPLY ONE DISADVANTAGE: THEY ARE OFTEN BUILT IN AREAS OF NATURAL BEAUTY

17. Generating electricity by conversion of the energy of running water

18. a fuel (such as coal, oil, or natural gas) formed in the earth from plant or animal remains How do we know how to find oil (the remains of dead SEA creatures? seismic machines send out sound waves

20. ENERGY DERIVED FROM THE HEAT IN THE INTERIOR OF THE EARTH

21. THE ENERGY RELEASED BY A NUCLEAR REACTION, ESPECIALLY BY FISSION OR FUSION. NUCLEAR ENERGY IS REGARDED AS A NONRENEWABLE SOURCE OF POWER.

23. ENERGY GENERATED FROM THE MOVEMENT OF TIDES

24. ENERGY GENERATED BY THE CONSTANT MOVEMENT OF WAVES AND USED TO PRODUCE ELECTRICITY

25. Biomass is the common name for organic materials used as renewable energy sources such as; wood, crops, and waste.

26. resources that are used up faster than they can be replenished.

27. A resource that can be replaced in time after being used.

28. RELATING TO OR BEING CONCERNED WITH THE ECOLOGICAL CONSEQUENCES OF ALTERING THE ENVIRONMENT.

29. Typically Nonrenewable Resources impact the environment more negatively than Renewable Resources.

30. Renew a Bean Goal Increase your understanding of the eventual depletion of nonrenewable resources and how it affects your future The Activity Materials: 100 beans in a zip lock bag for each partner group. 92% of one color, 8% of another color. Data sheets and Draw chart. Blindfolds.

31. Review: What does Renewable/Nonrenewable mean? What would happen if the soda machine in the teacher’s workroom was only filled at the beginning of the year? How long would the sodas last? What then? Count your beans 92:8 and put them in a zip lock bag.

32. Renewables Data Sheet The US depends on Nonrenewable Energy Resources Our population is constantly growing What will eventually happen? What are some possible solutions?

33. Draw Charts Draw chart 1: represents population that is using energy without thinking about whether it is renewable or nonrenewable Predict how many years it will take to deplete the beans in the container. Record it on Data Chart #1.

34. Directions One student blindly draws the beans from the container. Any renewable beans can be replaced and counted for that year. Continue until there are only renewable beans left in the container. Calculate the percentages after each drawing. Record the number of years it took to deplete all nonrenewable beans. Compare to your earlier predictions. Repeat the same steps for Data Chart 2 or 3. Use Data Charts 3 and 4 to design a way to extend energy use. Answer the follow up questions.
