  1. How Human Energy Systems depend on CARBON and CHEMICAL ENERGY from FOSSIL FUELS

  2. What are fossil fuels? Driving question

  3. Examples of fossil fuels coal oil gasoline natural gas

  4. Is gasoline organic or inorganic? ZOOMING INTO FOSSIL FUELS

  5. What we see… Macroscopic Scale GASOLINE

  6. Zooming in… Atomic-molecular Scale Gasoline (C8H18)

  7. What is gasoline most similar to in terms of atoms? Water molecule (H2O) Ethanol molecule (C2H6O) Gasoline (C8H18) Cellulose (C6H10O5)m Carbon dioxide (CO2)

  8. What is gasoline most similar to in terms of bonds? Water molecule (H2O) Ethanol molecule (C2H6O) Gasoline (C8H18) Cellulose (C6H10O5)m Carbon dioxide (CO2)

  9. Which group would gasoline fit into? ORGANIC INORGANIC --means the molecule is CARBON-BASED --and the molecule has C-C and C-H bonds --means the molecule is not CARBON-BASED --and the molecule does not have C-C and C-H bonds

  10. How did fossil fuels form? FOLLOW THE CARBON

  11. Over millions of years… …coal and other fossil fuels are formed from plant materials

  12. CO2 photosynthesis 300 million years ago

  13. Follow the carbon CO2 photosynthesis Buried Extracted from the ground squished & heated 300 million yrs ago today

  14. How do humans use fossil fuels, and when did we begin using them? Driving question

  15. Industrial revolution 1750 -1850– Changes in agriculture, manufacturing, mining, transportation and technology

  16. 300 million year old organic carbon Organic fossil fuels provide stored energy for human systems

  17. Combustion of fossil fuel releases CO2 This CO2 is called carbon emissions 300 million year old organic carbon

  18. Carbon emissions (CO2 released from burning fossil fuels) are also called greenhouse gases, because they amplify the greenhouse effect.

  19. More CO2 in the atmosphere traps more of the sun’s energy, heating the planet
