DO NOW: Mon 1/10
1. Finish Chapter 12 Vocab. – pg. 308 /new
book 340
***QUIZ TOMORROW***NO NOTEBOOKS
2. Open notebooks to a blank, new page
3. Write down all the gasses that you think are
found in CLEAN atmospheric air.
4. Write down any gases you think HUMANS
add to the air to pollute it.
Clean Air
 Nitrogen (78%)
 Oxygen (21%)
 Carbon Dioxide
 Water Vapor
 Argon
Primary vs. Secondary
 Primary Pollutants
 put directly into air by humans
 Secondary Pollutants
 when primary pollutants react with
others in air – Ex: ozone, NO2, acid rain
Air Pollutants
 Carbon Monoxide
 Nitrogen Oxides (NOx)
 Sulfur Dioxide (SO2)
 Ozone
 Lead
 Particulate Matter
Why is carbon monoxide harmful? What
does it do to you?

Motor Vehicle Emissions
 1/3 air pollution  vehicles
 Carbon monoxide, nitrogen oxides, particulate
matter, unburned fuel
 1970 Clean Air Act  EPA regulates emissions
 Catalytic Converters  clean exhaust gases
Evaluating Your Car Use
 Write down all the places you drive to or
walk/bike to on a weekly basis (school, work,
doctor, friend’s house, store, sports practice,
gym, movies, mall)
 Go to maps.google.com & find the distance
from your house to each of these places
 School address: 63 Tindall Rd.
Evaluating Your Car Use
1. What is the closest distance you travel by car?
2. What is the farthest distance you travel by car?
3. What is the farthest distance you walk/bike?
4. What is the closest distance you walk/bike?
5. Do you think there are any trips you could make
by foot/bike instead of car?
6. Do you think Middletown is a pedestrian/bike
friendly town? Why/why not? What could be
done to improve that?
