First things first
• I need to sign pre-labs• Clean your lab tables thoroughly• Wash your hands (in the room or go to the
restroom)• Lab tables should be free of backpacks, books,
purses, etc.
Energy
• Unit 4 - Ch’s 12- 14: Energy. Of HUGE economic, environmental, political importance!
• What are fossil fuels?
• How are they made?
• Types?
Red containers
• Desert ecosystem (use your imagination)
• Deserts often contain fossil fuel deposits
What you will be mining
1. Oil – filling of hostess cupcakes• What happens if you remove the whole
rock?• EPA (me) won’t buy back your land if it’s
riddled with sinkholes.
2. Coal Deposits – the chocolate chips in the chocolate chip cookies (cookie part is sedimentary rock)
3. Loose Ore Deposits – M&M’s
Methods
• Wind erosion – OK
• Drilling – OK
• Scraping the surface/ digging - OK
• Extreme weather events (earthquakes, tsunamis, turning the planet upside down) – NOT OK.
Economics
• You will start off in debt.– Must pay for land, supplies, labor…
• You will make a profit (hopefully).– Ore, coal, oil, land sale back to the EPA
Details
• Plates/ baggies are free
• Place your oil in the corner of a ziplock and I will estimate # of mLs
• Can use phone or clock as stopwatch
• Remember… the EPA is watching! Any major biota degradation will result in a loss of resale of land.
How to proceed
1. Spend a few minutes planning (this time is free!)
2. Buy equipment
3. Start mining (MUST run a timer!!!)
4. Calculate net gain
5. Eat ecosystem
6. Clean up!!!
