  1. What can students do about global warming? Sara Krauskopf (Madison East High School) Great Lakes Bioenergy Research Center

  2. Advanced Biology class--11 and 12th grade • All students have taken one year of biology and chemistry

  3. Overview of Advanced Biology Global Warming Unit • Guest speaker introduction • Review of atmosphere—distinguish greenhouse effect from ozone layer from global climate change • Examples of effects of global climate change, esp biological/ecosystem changes • Sources of air pollution and effects on human health • Wisconsin contributions stats • East High electricity bill/ retrofitting projects • Home electricity audit • Group research projects on topics related to air pollution/alternative fuels/effects of global climate change

  4. Wisconsin Energy Statistics 2006Wisconsin Division of Energy--Department of Administration

  5. Wisconsin Energy Statistics 2006Wisconsin Division of Energy--Department of Administration • Google “Wisconsin Energy Statistics” or “Wisconsin Division of Energy” • pdf file to download or view online • two versions available--condensed and complete

  6. What is a kilowatt? Visual demonstration of a kilowatt (10 100W bulbs) If we left these on for one hour, this would be one kilowatt hour.

  7. Conversion Rates(Coal-fired electricity) • CO2= 1 kg/KWH • SO2 = 5.8 grams/KWH • NOx = 2.5 g/KWH • Electricity $.10 per KWH. Use local rates from utility companies. Source Madison Gas and Electric

  8. Local Utility Bills • School bills--obtain from District Facilities Manager or KEEP course (UWSP) • Bring in home bills/photocopy yours • Discuss various charges • Peak/offpeak rates • Distribution service/KWH + Electricity Service per KWH

  9. Madison East’s Energy Bill

  10. Home Energy Bill

  11. Electricity Audit of Your Home Analyze the amount of electricity used in your home. Choose one room that has the greatest number of appliances and lights to use for the audit (You may do two rooms for up to 10 points extra credit). Create a data table showing the name of the room, appliances, wattage for each appliance, hours used per week, total watt-hours used per week and total KWH. • a. To determine wattage, look directly on the back or bottom of the appliance to get an accurate number. (Remember watts=volts x amps) Otherwise use the appliance survey sheet for assistance.

  12. 21 students—pledged 27,670 lbs CO2 of savings (12,577 kg)

  13. East High Unplugged • http://www.mmsd.org/mmsdtv/streaming/4269-snews-unplugged.mov

  15. MGE Website Earth Science students bring in an energy bill from their home or use the computer lab to find out the average energy use for their home. http://www.mge.com/myaccount/averagecost/

  16. Home Energy Audit Adapted from Project Learning Tree Scaffolded in its design Students have one week to do the energy survey at home, math calculations are done together in class.

  17. Wattages of Small and Medium Sized Electrical Appliances

  18. Calculation Sheet – Can we save a ton of CO2?

  19. Leaking Watts Chart Small appliances use energy when they are turned off but still plugged in.

  20. Overview of Earth Science Energy Use • What is a watt? • Where does our energy come from? • Reading a home energy bill (or MG&E website) • Waste Watchers Energy Survey – Can we save a ton of CO2? • Energy survey calculations • School energy bill • Graphing school energy use • Investigating alternative energy sources
