Particulates are solid particles or liquids in the atmosphere. Particulates can settle on surfaces. Particles can provide surfaces on which water condenses. This can increase fog, clouds, and rain depending upon weather conditions. The sulfur oxides then readily dissolve into existing droplets.
Particulates can substantially reduce visibility, which can increase accidents.
Particulates will reflect incoming solar radiation. Ozone is a secondary pollutant formed by a chemical reaction between gases in the presence of high temperatures and sunlight. To monitor these air pollutants, students will use simple measuring devices. In the case of particulates, they will capture solid particles using an index card with a hole covered with sticky tape. Goals for Project Clean Air Students will investigate types of air pollution.
