METHODOLOGY
Method 1 - Using Sticky Tape
By applying this method, I am able to find out the air quality by counting the particles collected on the sticky tape.
Steps :
To achieve a fair result, I have placed 24 tapes at different locations around my neighbourhood for 24 hours. The locations are the same places I went for my particle count collection (method 2). After a day, I collected the tapes and compared them by counting the particles stuck on the tape. However, I don't think this method is effective compared to method 2. This is because many factors could lead to a misleading result, for example, some of my tape was found on the floor instead of on the pole, some of them got leafs and gum on them and worst of all is some of them are gone. Besides, I think counting the particles don't really give me a clear idea of how polluted the air was because our air is polluted by air particles that are smaller than 10 microns meaning it can't be seen with bare eyes. Therefore, the result I have conducted wasn't as useful as I thought.
Steps :
- Attach pieces of double sided sticky tape around stakes or telegraph poles, lamp posts or trees (above the height of being easily reached) and remove the cover to expose the sticky surface of the tape.
- Leave the tape for 24 hours before removing the tape and examine the tapes to compare the particulate build up.
- To examine changes in particulate build-up over time, several strips can be mounted on card attached to a stake and left out. Each day one strip is uncovered, with the last being removed when the card is collected in (the control). The particulate can then be examined, and different sites compared.

Method 2 - Using Particle Counter
This method involve using a machine which collects particles sized from 0.5 -0.7 microns for one and a half minute.
Steps :
Steps :
- Fully charged the instrument.
- Place the tube onto the instrument.
- Turn on the instrument.
- Go to the location( outdoor).
- Press run on the instrument and hold it up high.
- Wait until the instrument stop running.
- Read and record the number of particles collected.
- Repeat each steps for different location.
Method 3 - Survey
A survey is often carried out to observe other's opinion on an issue/incident. In this case, my survey is about air quality in Kuala Lumpur. The survey was sent to my friends and schoolmates who live around KL and Taman Salak Selatan. It was open to public for 5 days and I've gathered 64 survey results. I think theresult I've collected are really useful as every individual's opinion differs, this will broaden my knowledge while analysing the results . On the survey, individuals will need to answer 10 questions related to air quality and what are the possible factors that contribute to air quality in Kuala Lumpur.
The link below is the survey I have created.

This method is very effective because it provides me a wide range of answer which allow me assume the factors that contribute to air quality easier with their opinion. On the other hand, 64 people have participated in doing the survey, this had made the survey more reliable because the more individuals have chosen the same answer, the more likely the possible cause it would be. The results I have collected would help a lot when it come to analysing the data and try to come up with possible causes.
One of the struggles while conducting the survey was reading the short answers. Out of 64 survey results, 4 participants didn't take the survey seriously and this had caused the survey to be a little unjust. have faced was going through some of short answers I have collected. TEven though I have 64 survey results, some people did not take it seriously as they answered the short answer part that does not make sense. This had made the survey harder to analyse because possible of it to be random chose answer can be high too. But this only occurred to a view surveys.

Method 4 - Interview
For the interview, I I made an attempt to the Department Of Environment Malaysia to interview Madam Ezahtulsyahreen Ab Rahman, Head of Air Pollution Department to get more information on air quality in KL.
