1. Today is Wednesday, Dec. 4, 2013 HOMEWORK: Read Chapter 10, Lesson 3
Warm UP: Tell your shoulder partner one form of NON-RENEWABLE ENERGY (review from yesterday) as well as one form of RENEWABLE ENERGY (this is what we will be talking about today).

2. Helping us reach our Standard….
Goal for Today
SWBAT demonstrate the ability to recognize wind, solar, and hydroelectric energy as types of renewable energy resources by discussing advantages and disadvantages of these renewable resources.
Helping us reach our Standard….
5-ESS3-1 Obtain and combine information about ways individual communities use science ideas to protect the Earth’s resources and environment.

3. Exxon-Valdez Oil Spill
Prince-William Sound, Alaska
1989

7. Deepwater Horizon Oil Rig Explosion
Gulf of Mexico, United States
April, 2010

8. Shrimp boats equipped with booms collect oil in Chandeleur Sound, La
Shrimp boats equipped with booms collect oil in Chandeleur Sound, La., on May 5.

9. An oil-soaked bird struggles against the side of an Iron Horse supply vessel at the site of the oil spill off Louisiana on May 9.

10. An aerial view of the northern Chandeleur barrier islands, 20 miles from the main Louisiana coastline, shows sheens of oil reaching land May 6.

11. Oil swirls in the Gulf of Mexico currents May 6.

12. A Greenpeace worker collects samples of oil May 19 that washed up along the mouth of the Mississippi River near Venice, La.

13. An oil-covered dragonfly, stuck to marsh grass, tries to clean itself May 18 in Garden Island Bay near Venice.

14. Renewable Resources Wed., Dec. 4, 2013

15. Solar Energy Renewable Energy from sunlight
Heats water  boils  steam turns turbine to make electricity
Advantages:
No air pollution
Unlimited supply

16. Disadvantages:
Not always available
Expensive to make and maintain
Solar cell production makes dangerous wastes

17. Wind Energy
Wind turbines uses wind energy to spin a generator  electricity
Advantages:
No air pollution
Disadvantage:
-Wind doesn’t blow all the time
-Can kill birds -Noisy and ugly
- Possible unknown future consequences of global wind patterns

18. Using Wind Energy in a New Way
Wind Belt
Using Wind Energy in a New Way

19. Uses flowing water to spin generator
Hydroelectric Energy
Uses flowing water to spin generator
Most of Washington State (home of Ali and Mr. Gross) runs off of this power
Advantages:
No fuel needed
No pollution
No waste left behind

20. China, Yangtze River Three Gorges Dam
Disadvantages:
Only built by moving water
Place where lake can form behind the dam
Lakes flood habitats
Dams stop fish swimming up and down river
Though a very, very rare occurrence, disasters (i.e. dam breaking) can be extremely horrific and far-reaching in their destruction
China, Yangtze River
Three Gorges Dam

23. Closing it up….
Tell your shoulder partner what you think the BEST form of energy we have talked about today is and WHY you think it is the best.

24. Today is Thursday, Dec. 5, 2013 Homework: Read Chapter 10, Lesson 4
Warm Up: With your FACE PARTNER, recall one form of renewable energy we discussed in class yesterday. Give one pro (advantage) and one con (disadvantage) of using this type of energy.

25. Helping us reach our Standard….
Goal for Today
SWBAT demonstrate the ability to recognize nuclear, geothermal and biomass as types of renewable energy resources by discussing advantages and disadvantages of these renewable resources.
Helping us reach our Standard….
5-ESS3-1 Obtain and combine information about ways individual communities use science ideas to protect the Earth’s resources and environment.

26. The Nukes!!!!!

27. Heats water  boils  steam turns turbine to make electricity
Nuclear Energy
Uses uranium as fuel
Advantages
Needs much less fuel
Doesn’t give off smoke
Disadvantages
Very expensive (to get up and running safely in the first place, cheaper after that)
Dangerous wastes
Nonrenewable (but lasts a long time)

28. How Fission Splits the Uranium Atom
                                
This process creates
heat (when forced
chain reaction occurs
phenomenal amounts
of heat are created, i.e. in bomb,
where the military expression “Turn the desert
in to glass” comes from)

29. Nuclear Power Plant Accident
Chernobyl, Ukraine (Ukraine S.S.R. at the time)
1986

30. Largest man-made release of nuclear energy in the history of the world.
This was a disaster!!! (not done on purpose!!!)

36. Geothermal Energy
Uses energy from the high temperatures inside the Earth
Advantages
Available all the time

40. Disadvantages
Only available in few places in the world
Expensive to build in the first place
Some natural pollutants in the steam of the power plants.

41. Biomass
Biomass – material that was recently alive, like animal waste, wood, grasses, or food waste
Uses biomass to burn as fuel for power plants

42. Advantages
Unlimited supply
Less garbage will take up landfills

43. Disadvantage
Causes air pollution

45. Closing it up….
Of all the forms of renewable energy we have discussed in class, in your table groups discuss and come up with 1 or 2 that you think are THE BEST. Pick a spokesperson from your table to explain to the class why you have chosen the one or two that you have chosen (why they are the best!!!!).            
