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.

Aerosols, AQP,  CO2*, GASPer, Greenhouse gas, Ozone , Eye on Ozone, Ozone*Depletion, PADEPBAQ, (Zikua) ,
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?
