• “Clean Car Campaign” Article– Please read the article that was
handed out to you in the beginning of class
– Underline words/phrases we have discussed so far this unit
– Answers this question at the end of the article:• What is the ‘main idea’ of this article?
– Put your pen/pencil down when you have completed the reading
“Why Clean Cars?” – Important Words/Phrases:
• Air pollution • Emissions • Global warming • Quality of life • Public Health• Motor vehicles • Smog • Fine-particle soot• Toxic chemicals • Cancer• Environmental Protection Agency
(EPA)• Ozone • Asthma attacks
• Emergency room visits • Premature death• Higher temperatures • Unhealthy air • Pollen levels • Allergens • Hospitalizations• Cars, SUVs and pickup trucks • Nitrogen oxides • Coal-burning electric power
companies• Carbon dioxide emissions• Carbon monoxide • Hydrocarbons
“Why Clean Cars?” – The Big Idea
“The U.S. Energy Information Administration has projected that global warming pollution from motor vehicles will continue to increase in the next quarter-century unless we curb motor vehicle emissions.”
“Why Clean Cars?” – What can we do?
• Learn how to analyze which vehicles emit the most pollution and carbon emissions into the atmosphere
• Learn how to find vehicles that are the most efficient with fossil fuels
• Learn how to shop for what vehicles that are the best for the consumer and the environment in that person’s geographical area
Car Activity:Air Pollution Lesson
Objectives:1.TSWBAT analyze relationship between environmental factors and
community health2.TSWBAT compare fueling efficiency of different model cars to
determine the effect of auto emissions3.TSWBAT evaluate how cars contribute to air pollution
What About Vehicle Emissions?!
• What comes from exhaust:– Carbon Monoxide– Sulfur Oxides– Nitrogen Oxides
• Evaporative Emissions– Car ‘running’ but in park
• Refueling Losses– Fueling during day vs. night
Montgomery County
• North Penn is purchasing ultra-low sulfur diesel fuel & retrofitting a portion of its school bus fleet with oxidation catalysts. – one of the largest school bus fleets in PA – serves 12,000 students – Partners include Pennsylvania DEP
• SEPTA – Regional Rail• Bike trails

Car Activity Example
This slide is a guide for you to do this activity with TWO cars of your choice.
1997-2011 9/2011 - ???
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 / 2825+31=5656/2=28
28 /39 / 33.528+39=6767/2=33.5
Gallons used per year (based on 15,000 miles per year, combined driving)
15000 / 28 = 535.71
15000 / 33.5 = 447.76
Pounds of CO2produced per year (One gallon of gas burned produces 20 pounds of CO2
535.71 x 20 = 10,714.20
447.76 x 20 = 8955.20
Price of unleaded gas (per gallon) $____/GALLON
$2.89 $2.89
Amount spent on gas for one year (in $) (price x gallons/year based on 15,000 miles per year)
$2.89 x 535.71 = $1548.20
$2.89 x 447.76 = $1294.02
10-year cost of vehicle $1548.20 x 10 = $15,482.00
$1294.02 X 10 = $12,940.20
