Transcript With a partner discuss which of the following ways of air pollution

CAR ACTIVITY:
AIR POLLUTION LESSON
Objectives:
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
1.
WHICH OF THE FOLLOWING WAYS
OF AIR POLLUTION ARE YOU
MUST RESPONSIBLE FOR?
Rank 1 – 4:
Radon
Asbestos
Vehicle Emissions
Acid Rain
What in a car interest you?

 Exhaust
 (What comes from
exhaust)
 Evaporative Emissions
 Refueling Losses

Car
Activity
Example
This slide is a guide for you to do
this activity with three cars of your
choice.
Year, make and model
1997 Honda Accord
Purchase price
$21,000 (1997)
$2000 (today?)
Miles per gallon:
City / highway /
AVERAGE
23-25 / 30-32 / 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
…TBA…
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 =
16,054.09
Discussion Questions
 1. How many pounds of CO2 would you save over ten years by buying the
more efficient vehicle? (subtract the difference and multiply by 10)
 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?
