Students learn what causes air pollution and how to investigate the different pollutants that exist, such as toxic gases and particulate matter. They investigate the technologies developed by engineers to reduce air pollution.

Engineers continually work to prevent pollution so our air is safe to breathe. One mechanical engineering invention is a catalytic converter that reduces smog by changing hydrocarbons and carbon monoxide in automobile exhaust into less harmful carbon dioxide and water vapor. Engineers continue to explore new, creative ideas to lower the emissions into the air, such as designing more efficient vehicles, industrial filters to reduce the amount of particulate matter released into the atmosphere, and indoor air filters to keep our indoor air clean.Identify some of the major causes and characteristics of air pollution.List several technologies developed by engineers to reduce air pollution.Identify resource-related activities that they could do to reduce air pollution.Describe some historical events that occurred because of air pollution. 50TeachEngineering.orgMalinda Schaefer ZarskeJanet YowellMelissa StratenEdward, A.
