Air Pollution
Experiment (CAR): Air Pollutants
Defined / CAPCO
Air pollution is the
addition of harmful substances to the atmosphere. Air pollution directly
affects
our health and well-being. It also affects the environment, which indirectly
affects
our health and reduces our quality of life. This experiment will allow
students to see air
pollutants that are the result of vehicle
emissions.

Carbon monoxide (CO), a colorless, odorless gas,
results from incomplete fuel combustion.
Nitrogen oxides (NOx) are the result of subjecting nitrogen and oxygen in the air to high temperature and high pressure conditions in an internal-combustion engine.
Hydrocarbons (HC) result from unburned or partially burned fuel molecules or from fuel evaporation. Some hydrocarbons react with NOx in the presence of sunlight to form ozone.
Particulate matters (PM10) are the small particles, that may or may not be visible, that make up pollutants.
Materials:
Petroleum jelly
or reversed scotch tape
Magnifying
glass or microscopes
3" x 5" (7 cm x 12 cm) index cards
Procedure:
1. Tape a grid on to the index
card
( will use to count pollution later under microscope).
2.
Smear petroleum jelly
or reversed scotch tape
on a
card .
3. Hold the card near the tail pipe or exhaust system of a
diesel-fueled vehicle when it is started.
CARE:
DO NOT TOUCH EXHAUST PIPE !
4. Do the same thing
with a vehicle fueled by gasoline, natural gas, electricity, propane, or other
alternative fuel. You can also use electric or gasoline fueled lawn and garden
equipment, construction equipment or fork lifts.
5. Look at the cards
under a magnifying glass or stereomicroscope.
6. Which cards show the most
pollutants?
Give
black carbon density= __________,
7. The least?

8. Make a line graph to
illustrate your findings.

Air Pollution Experiment (Wind):
Air pollution is the
addition of harmful substances to the atmosphere. Air pollution directly affects
our health and well-being. It also affects the environment, which indirectly
affects our health and reduces our quality of life. This experiment will allow
students to see air pollutants.
Carbon monoxide (CO), a colorless, odorless gas, results from incomplete fuel
combustion.
Nitrogen oxides (NOx) are
the result of subjecting nitrogen and oxygen in the air to high temperature and
high pressure conditions in an internal-combustion engine.
Hydrocarbons (HC) result
from unburned or partially burned fuel molecules or from fuel evaporation. Some
hydrocarbons react with NOx in the presence of sunlight to form ozone.
Particulate matters (PM10)
are the small particles, that may or may not be visible, that make up
pollutants.
PURPOSE: One of the ways to study wind is to
see what is being blown in the wind.
ACE
monitors several types of particles,
SWEPAM,
for example, checks electrons, protons, and alpha particles. In this activity
you will make a device that will collect particles from the earth's wind.
MATERIALS:
5" X 8" grid card, contact paper or scotch tape, , wind speed indicator,
compass.
PROCEDURE:
PART I
Collector Construction:
1. Use the grid card.
2. Mark the grid card with
the direction the card was facing: N W S E and location.
3. Tape or tie the
collection card so the wind doesn’t blow it away.
4. Cover the grid card
with a piece of reverse sided contact paper or cover the window in tape (sticky
side up).
5. Place the grid card in
the collector above the weight.
6. Orient the box/ grid
card on the ground with the compass direction desired.
PART II:
Collecting
particles and analysis: (Each person should pick a different location to collect data).
1.
Work with others in your groups to form a
line, or pattern, or array of devices (organization). Select your
variables, such as positions (W, N, E, S) or distances.
2. Use small folded collectors with string for testing:
3. Check wind speed and
direction if used outside.
DATA:
1. Collect the grid cards.
2. Examine the grid cards under the magnifying glass*: give black carbon
density=__________,
count and
record particles*
3. Compare the directional data with other groups.
Did you get the
same data? ____________________________
Which location
was the worst?___________________________
4. What types of information can be determined by these devices?
