2. Warm Up 1. Turn in your “Carbon Footprint Quiz” 2. Take out your “Vanishing Resources” worksheet and have it out on your desk. 3. How do fossil fuels form? 4. What two elements are they made of? 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, Mining, and Fracking

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  Marine organisms  Brown/black thick liquid  Extraction  Drilling  Fracking  Refined – distillation Refined  Heated to a gas  Cooled to various liquids or gasses  Make many different things

9. Petroleum – Where?

11. Petroleum Advantages (Pros) Disadvantages (Cons)

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

13. Combustion Demo

14. 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

15. Fracking – Where?Where?

16. 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 Tuesday/Wednesday!!
