1. Objectives: 1. TSWBAT analyze relationship between environmental factors and community health 2. TSWBAT compare fueling efficiency of different model cars to determine the effect of auto emissions 3. TSWBAT evaluate how cars contribute to air pollution

2. What in a car interest you?

3. What About Vehicle Emissions  Exhaust (What comes from exhaust)  Evaporative Emissions  Refueling Losses

8. Car Activity Example This slide is a guide for you to do this activity with three cars of your choice. 1997-20119/11 - ??? Year, make and model 1997 Honda Accord LX 2012 Honda Civic LX Purchase price $21,000$19,000 Miles per gallon: City / highway / combo 25 / 31 / 2728 /39 / 32 Gallons used per year (based on 15,000 miles per year, combined driving) 15000 / 27 = 555.55 15000 / 32 = 468.75 Pounds of CO2 produced per year (One gallon of gas burned produces 20 pounds of CO2 555.55 x 20 = 11,111 468.75 x 20 = 9375 Price of unleaded gas (per gallon) $____/GALLON $3.41 Amount spent on gas for one year (in $) (price x gallons/year based on 15,000 miles per year) $3.41 x 555.55 = $1894.42 $3.41 x 468.75 = $1598.43 10-year cost of vehicle $1894.42x 10 = $18,944.20 $1598.43 X 10 = $15,984.30

9. Discussion Questions  1. How many pounds of CO2 would you save over ten years by buying the more efficient vehicle?  2. Should cars that pollute more cost more? Why or why not?  3. Why do you think SUVs are so popular with drivers today, given their low mileage and significant greenhouse gas emissions?  4. What do you think would motivate drivers to buy cleaner, less-polluting vehicles instead?  5. Should there be incentives for people to drive hybrids, such as being allowed in the HOV (high occupancy vehicles) lanes?
