    INTRODUCTION

    Particulates in the air vary from location to location within the area. Air particles are tiny

    subdivisions of solid matter suspended in a gas or liquid. In contrast, aerosol refers to particles

    and liquid droplets and the gas together. Sources of particulate matter can be manmade or

    natural. Large amount of air particles in the environment is the main cause of air pollution which

    can bring various implications such as health problem and reduce visibility.

    The air we breathe has a lot do with our health. As we breathe in fresh air, our lungs absorb

    oxygen from the air and pass it into our blood stream so it can be transported throughout our

    bodies. Oxygen is important for our whole body to have the energy it needs to survive.

    It is important for all of us to have clean air to breath. People living in industrial areas are more

    likely to develop asthma. People who smoke are more likely to suffer from lung disease. You

    may have seen an example of the lungs from a smoker which is small, black and unhealthy

    looking. Years and years of breathing particles of tar and smoke can cause the lung tissue to

    develop cancer, and can even cause death.

    Breathing clean air is important for keeping your lungs nice and healthy. Tiny particles of dust

    and soot in the air can enter your lungs when you breathe, and can block the movement of

    oxygen. Harmful particles can come from pollutants in the air like dust, smog, soot, smoke, and

    other chemicals. Because of the importance of clean air to our health, most cities keep track of

    air pollution by issuing smog warnings on days when there is a high level of air pollution.

    OBJECTIVE

    1. To understand and implement suitable methods to prove the existing of particles insurrounding area.

    2. To develop a team exercise where student groups might each understand and write ahypothesis, list the materials used and the number of each item, and a procedure.

    DISCUSSION

    1. What are the contributing factors of particle presence at each site?The contributing factors of particle presence at each site such as a smoke from smoker

    and an unhygienic environment that is not clean.

    2. How would you design this experiment differently the next time?For more accurate reading, the other options may be useful. The other apparatus can be

    used such as fly paper. The papers have glue that can catch the particles around it. The

    other option is by choosing the other place. Good locations are at the back yard, a busy

    street corner, school, a park, a shopping center, a parking lot, etc.

    3. What are the possible factors which may influence the result attained?The possible cause that influences the result is the weather and temperature. Rainy day

    will wash the dust and hot temperature will dry out the grease and reduce the sticky

    ability. Besides, the equipment used also effect the result. Stickier agent can produce

    more accurate result.

    CONCLUSION

    For the conclusion, the suitable methods to prove the existing of particles in surrounding

    area were understood and implemented. The existing of the particles in the air was contributing

    the air pollution. The best method to identify the existing of the air particle is just like what the

    laboratory test was done.

    Besides that, a team exercise was made. The student group was each understood and able

    to wrote a hypothesis, list the materials used and the number of each item, and a procedure. The

    hypothesis made is, the more particles in the air at a certain location, the more hazards in the air.

    This experiment shows that there are a lot of particles in the surrounding area. Therefore,

    any precaution action should be taken to providing a good breathing air and having a good

    health.

    SAFETY AND HEALTH

    1. The experiment should be done carefully to get the better result.2. The paper was used must be care so that the particle not less.
