Class 4–6
Dust Collection Test
What you need
- 2–3 clean sheets of white paper or plain cards
- Petroleum jelly
- Tape
- Labels
- Notebook
Method
- Put a thin layer of petroleum jelly on each card.
- Label the cards with their locations.
- Place them in different suitable locations, such as near a road and in a relatively less busy area.
- Leave them for the same amount of time.
- Compare the visible particles collected on each card.
What to observe
Record whether one location appears to have more visible dust or particles than another.
What this project demonstrates
It can help students understand that airborne particles can settle on surfaces and that particle deposition may differ between locations.
Important: This is a simple observation project. It does not measure PM2.5, PM10, or AQI.
Class 5–7
Air Pollution Source Survey
What you need
- Notebook or observation sheet
- Pen
- Optional: simple tally chart
Method
- Choose a safe observation area around your school or neighbourhood.
- Identify visible or known pollution sources such as vehicle traffic, construction dust, or open burning.
- Record the source, location, and time.
- Repeat the observation at more than one suitable location or time.
- Organise your observations into a simple table.
What to observe
Look for differences in the types and frequency of pollution sources observed at different locations or times.
What this project demonstrates
Pollution can come from multiple sources, and the sources present can vary by location and activity.
Class 6–8
Traffic and Air Pollution Observation
What you need
- Notebook
- Observation table
- Clock or phone timer
Method
- Choose a safe location where traffic can be observed without standing close to moving vehicles.
- Select two or more observation periods.
- Record approximate traffic activity during each period.
- Note visible smoke, dust, or other relevant observations.
- Compare your observations.
What to observe
Compare traffic activity with the visible pollution indicators you recorded.
What this project demonstrates
Traffic activity can be one contributor to air pollution, but a simple observation cannot establish how much pollution a source produces.
Class 8–10
AQI Data Analysis Project
What you need
- A computer or notebook
- Publicly available AQI data
- Spreadsheet or graph paper
Method
- Select one Indian city or more than one city.
- Collect AQI data for a clearly defined period from a reliable public source.
- Record the date and AQI value.
- Organise the data in a table.
- Create a simple line or bar graph.
- Identify noticeable changes or patterns.
What to observe
Look for changes in AQI over the selected period and differences between locations if you compare more than one city.
What this project demonstrates
Public air-quality data can be organised and analysed to identify patterns in reported air-quality conditions.
How to Present Your Air Pollution Science Project
A good science project should explain not only what you did, but also what you observed and what the project can and cannot show.
Before You Present
- Explain the project objective in one or two sentences.
- List the materials and describe the method clearly.
- Show your observations in a table, chart, or simple graph when useful.
- Explain what the observations suggest without claiming more than the project can demonstrate.
- Be ready to explain how you would improve the project if you repeated it.
Safety
- Do not stand close to moving traffic to collect observations.
- Carry out the project with a teacher or adult when supervision is needed.
- Do not handle unknown chemicals, polluted materials, or waste.
- Do not deliberately burn materials to create air pollution for an experiment.
- Do not approach open fires or burning waste to make observations.
- Follow your school’s science-project safety rules.
What Your Project Can and Cannot Show
A simple school project can help demonstrate an idea, compare observations, or analyse publicly available data. It should not be presented as a professional air-quality measurement unless appropriate monitoring equipment and methods are used.
For example, visible dust collected on a surface does not give a PM2.5 or PM10 concentration, and a simple traffic observation cannot determine exactly how much pollution vehicles produce.

How to Write Your Project Conclusion
A good conclusion should briefly state what you investigated, what you observed, and what the observation suggests. Do not add results that you did not actually collect.
Simple format
What I investigated → What I observed → What it suggests
Example
“I compared visible particle deposition at two locations. The card placed near the busier area appeared to collect more visible particles during the observation period. This suggests that particle deposition can vary between locations, although this simple test does not measure PM2.5 or PM10 concentrations.”
Air Pollution Science Project: Frequently Asked Questions
Which air pollution science project should I choose for my class?
Choose a project based on your class level, available materials, safety requirements, and the type of evidence you want to collect. Dust collection and source observation are suitable for simple observations, while AQI data analysis is more suitable when you want to work with public data and graphs.
Can I use a school science project to measure PM2.5?
Not with a simple dust-collection experiment. PM2.5 measurement requires appropriate equipment and methods.
Can I use online AQI data for my project?
Yes, when your teacher allows the use of public data. Record the source, location, date, and time period clearly, and explain what the data represents.
Should I invent results if my experiment does not work?
No. Report what you actually observed. If the result is unclear or the experiment has limitations, explain those limitations instead of creating a result.
Can I copy a science project from the internet?
You can use online examples for ideas, but you should adapt the project to your class requirements, follow your teacher’s instructions, and report your own observations or analysis. Do not present copied results as your own.
