  1. Baseload Energy Source • Baseload energy sources are the most commonly used energy sources. • Fossil Fuels (coal, oil) • Hydroelectric • Nuclear Energy

  2. Nuclear energy

  3. Nuclear energy #3.8 Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW • The energy that holds atoms together. How do we all use oil in our every-day lives?

  4. #3.8 Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW How does nuclear fission work? 2. These split apart and produce more neutrons… 3.…which then collide with other heavy, unstable atoms, and the process continues. 1. Neutrons are fired at heavy, unstable atoms.

  5. #3.8 Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW Using this chain-reaction with control gives us nuclear power Using this chain-reaction uncontrolled gives us a nuclear bomb

  6. #3.8 Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW What does nuclear energy require for fuel? • Uranium, an uncommon mineral that is mined.

  7. #3.8 Aim: Where does nuclear energy come from? Agenda QOD (10) Activity: Nuclear energy (15) Lesson: Nuclear energy (15) Summary (5) No HW Do you think nuclear energy is renewable or non-renewable?

  8. #3.9 Aim: What are the pros to using nuclear power? Agenda QOD (10) Lesson: Nuclear power plants (15) Activity: “Nukes are green” (15) Summary HW #20

  9. How do nuclear power plants work? #3.9 Aim: What are the pros to using nuclear power? Agenda QOD (10) Lesson: Nuclear power plants (15) Activity: “Nukes are green” (15) Summary HW #20 How do we all use oil in our every-day lives?

  10. Nuclear power plants #3.9 Aim: What are the pros to using nuclear power? Agenda QOD (10) Lesson: Nuclear power plants (15) Activity: “Nukes are green” (15) Summary HW #20 1. Fission occurs. Moderator – slows down neutrons (so that fission can happen) Control rods – absorb neutrons (to keep the chain-reaction in check) How do we all use oil in our every-day lives?

  11. Nuclear power plants #3.9 Aim: What are the pros to using nuclear power? Agenda QOD (10) Lesson: Nuclear power plants (15) Activity: “Nukes are green” (15) Summary HW #20 2. Fission heats up water 4. Steam drives the turbines, generating electricity! 3. Hot water boils, creating steam

  12. Nuclear power plants #3.9 Aim: What are the pros to using nuclear power? Agenda QOD (10) Lesson: Nuclear power plants (15) Activity: “Nukes are green” (15) Summary HW #20 5. Cold water from the cooling tower converts steam back to liquid water (it is recycled) How do we all use oil in our every-day lives?

  13. “Nukes are green” • We will read the article aloud, together • In your notes: make a list of pros of using nuclear power (at least four)

  14. #3.9 Aim: What are the pros to using nuclear power? Agenda QOD (10) Lesson: Nuclear power plants (15) Activity: “Nukes are green” (15) Summary HW #20 What are some of the pros to using nuclear power?

  15. #3.10 Aim: What are the cons to using nuclear power? Agenda QOD (10) Lesson: Nuclear power cons (15) Activity: WARNING PAMPHLETS (15) Summary (5) No HW There are two main problems with nuclear power…

  16. 1. Small risk of large accidents #3.10 Aim: What are the cons to using nuclear power? Agenda QOD (10) Lesson: Nuclear power cons (15) Activity: WARNING PAMPHLETS (15) Summary (5) No HW • Leaks from nuclear power plants can release radiation, which damages DNA  cancer, birth defects, etc. Birth defects from Uranium exposure Burns from radiation

  17. Three Mile Island Pennsylvania, 1979 #3.10 Aim: What are the cons to using nuclear power? Agenda QOD (10) Lesson: Nuclear power cons (15) Activity: WARNING PAMPHLETS (15) Summary (5) No HW Mechanical failure and human error caused the cooling water to drain from the reactor, melting the fuel rods and releasing radiation. Most radiation remained trapped inside and didn’t hurt anyone.

  18. Chernobyl Ukraine, 1986 #3.10 Aim: What are the cons to using nuclear power? Agenda QOD (10) Lesson: Nuclear power cons (15) Activity: WARNING PAMPHLETS (15) Summary (5) No HW An explosion destroyed the reactor and sent clouds radioactive debris into the air. Twenty-two people died. Red shows the radiation cloud Chernobyl victim with his brother

  19. #3.10 Aim: What are the cons to using nuclear power? Agenda QOD (10) Lesson: Nuclear power cons (15) Activity: WARNING PAMPHLETS (15) Summary (5) No HW 2. Produces toxic waste Used fuel rods emit radiation for thousands of years.

  20. #3.10 Aim: What are the cons to using nuclear power? Agenda QOD (10) Lesson: Nuclear power cons (15) Activity: WARNING PAMPHLETS (15) Summary (5) No HW U.S. power plants store enough radioactive waste to fill a football field 10 feet high This waste is stored in 125 sites across the country. The National Academy of Sciences reported that most of these sites are vulnerable to terrorist attacks.

  21. #3.10 Aim: What are the cons to using nuclear power? Agenda QOD (10) Lesson: Nuclear power cons (15) Activity: WARNING PAMPHLETS (15) Summary (5) No HW 3. Nuclear Weapons Countries could potentially generate nuclear energy for developing nuclear weapons. Nuclear power plants could serve as targets for terrorists attacks.

  22. #3.10 Aim: What are the cons to using nuclear power? Agenda QOD (10) Lesson: Nuclear power cons (15) Activity: WARNING PAMPHLETS (15) Summary (5) No HW

  23. #3.10 Aim: What are the cons to using nuclear power? Agenda QOD (10) Lesson: Nuclear power cons (15) Activity: WARNING PAMPHLETS (15) Summary (5) No HW Nuclear power: good idea or bad idea?
