Measuring Air Pollution

Introduction: Measuring Air Pollution

Abdallah Sendi


Subject: Science

Step 1: What the Topic?

Measuring the air particles in two areas, and those two are from very different slopes. Specifically, one in coastal highlands and one is coastal plains.

Step 2: What Is the Purpose of This Experiment?

Determine the number of particles in the air in a given area, specifically the coastal plains and coastal highlands.

Step 3: Whats the Research Question/problem?

Will, there show some air particles on the board pieces, or not?

Step 4: Variables: Dependent, Independent, Controlled

Dependent: The whiteboard trapping the air particles.

Independent: The weather/climate.

4 Controlled:-·

  • The air particles
  • The rope
  • The whiteboard (Not with the Vaseline on)
  • The height and width of the whiteboard

Step 5: Hypothesis

I will find particles stuck in pieces of the whiteboard, and the number of particles that I think is many in the highlands because the number of particles can either be a large quantity and a small number and the particles in the plains will be much lower.

Step 6: Procedures

1. Find an area where you can hang several pieces cut from the board. You can do this in your home if you want to know how clean the air in your home is, or you can hang your cut-out chalkboard pieces outside in your yard or other areas.

2. Draw a group of squares containing the marker on the blackboard.

3. Punch a hole in the top of the board and tie a piece of rope into the holes so you can hang the cutouts in different areas.

4. Smear a thin layer of Vaseline inside the drawn square.

5. Record your notes in your notebook after a week or so.

Step 7: The Result

Step 8: The Conclusion

Coastal Highlands (Doha Al Shamaliya) is more polluted than the Coastal Plains (Al-Rakah) due to: -

  • Wind activity raises dust in the low-lying area
  • Increasing population density
  • Its proximity to the industrial city

So Coastal Highlands or other place higher like mountains will be more polluted air than the other site below it, so like coastal highlands/hills will be more air pollution than plains.

Step 9: Data Analysis : Sources of Error, Trends in Data, Applications of Findings

Sources of error: The two whiteboards were pretty similar, the one in the plains wasn’t as low as I thought that was mentioned in the hypothesis. Data may be minimal and without a very clear image. Also, there should’ve been a specific amount of how much should the air particles take in the highlighted squares, which wasn’t mentioned.

Trends in data: The date the whiteboard is picked up is the same, and the results in both boards look pretty similar.

Applications of findings: Monitoring and measuring air quality is important because polluted air can be bad for our health, and the health of the environment, and the health of other organisms. However, instead of showing changes in the temperature, the air quality index (AQI) is a way of showing changes in the amount of pollution in the air.

Step 10: Method & Prediction Evaluation

Prediction Evaluation: I predict that the chance of success will be too high or too low, because of how the answers in each question or requirement are answered, with good details and points, but not too high because of how much it can still be added.

Method Evaluation: The method for success in the scientific investigation is to outline a problem or question to be tested by a scientific investigation, and outline a testable prediction using scientific reasoning outline how to manipulate the variables. And outline how sufficient, and relevant data will be collected. And last but not least is to design a logical, complete and safe method in which he or she selects appropriate materials and equipment. But you are finished, you make a presentation with all the information and the research you’ve gathered.
