2. Warm Up 1. List 2 things you think you know about fracking. 2. List 2 things you want to know about fracking. Time’s Up!

3. Vanishing Resources Discussion  Patterns in data?  Why did fossil fuels spike and then drop down very low?  Why did solar power grow at the end?  Did anyone run out of white beans or black beans in the last round?  What does running out of black beans represent?  Will this happen in real life at some point?  What does running out of white beans represent?  What could we do to add more white beans in the future?

4. Fossil Fuels

5. Coal  Fossil fuel  Dirtiest burner  Formed in former bog  Decaying plant/ animal material  Acidic  Pressure and time

6. Where and How?  Mining  Deep: Dangerous, health hazard (black lung)  Strip: Extreme environmental impact  Refinement  Transportation: Train  Mostly U.S.  Used for  Electricity

7. Coal  Advantages  Disadvantages

8. Petroleum  Fossil Fuel Fossil Fuel  Marine organisms  Brown/black thick liquid

9. Petroleum  Extraction  Drilling  Fracking  Refined – distillation Refined  Heated to a gas  Cooled to various liquids or gasses  Make many different things

10. Trans-Alaska Oil Pipeline  Why do you think this pipeline is elevated rather than buried in the ground?

12. Petroleum – Where?

14. Petroleum Advantages (Pros) Disadvantages (Cons)

15. Natural Gas  Lighter component of petroleum.  Methane  Odorless gas  Burns cleaner than other fossil fuels  Uses  Heating homes/water  Cooking  Transportation

16. Combustion Demo

17. Fracking  Use existing well  Drills horizontally  Pumps in  Water  Sand  Chemicals  High pressure  Breaks open rocks  Releases trapped oil and gas  Sand holds open cracks  Chemicals aids process  Products pumped out

18. Fracking – Where?Where?

19. Homework!!  Find at least TWO articles about pros and/or cons of fracking from the library search databases.  Find them!  Print them! (or take notes on them if you don’t have a printer)  Bring them with you to class on Monday!!
