Objectives:
1.
2.
TSWBAT compare fueling efficiency of different model
cars to determine the effect of auto emissions.
TSWBAT evaluate how cars contribute to air pollution and
affect our health.
Which of the following ways of
air pollution are YOU must
responsible for?
Rank 1 – 4:
Radon
Asbestos
Vehicle Emissions

Really Mr. Schreiber’s Car
Car Activity Example
Mr. Schreiber’s Car
Year, make and model
1999 Toyota Corolla
Purchase price
$ 6,500 (1999)
$ 3,000 (today)
Miles per gallon:
City / highway / combo
23-25/ 30-33 / 27
Gallons used per year
(based on 15,000 miles
per year,
combined driving)
15000/27 =
555.55
Pounds of CO2
produced per year
(One gallon of gas
burned produces
20 pounds of CO2
555.55 x 20 =
11,111
Price of unleaded gas
(per gallon)
$____/GALLON
$2.89
Amount spent on gas
for
one year (in $)
(price x gallons/year
based on 15,000
miles per year)
$2.89 x 555.55 =
$1,605.54
10-year cost of vehicle
1,605.54 x 10 =
$16,055.40
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, lesspolluting vehicles instead?
5. Should there be incentives for people to drive hybrids, such as
being allowed in the HOV
(high occupancy vehicles) lanes?
