Students identify types and sources of indoor air pollutants in their school and home environments. They evaluate actions that can be taken to reduce and prevent poor indoor air quality. In an associated literacy activity, students develop a persuasive peer-to-peer case against smoking with the goal to understand how language usage can influence perception, attitudes and behavior.

Indoor air pollutants can cause a variety of health impacts ranging from breathing complications to cancer. Mechanical engineers who design heating, venting and air conditioning systems for buildings continually work to improve indoor air quality. Their HVAC systems bring fresh outdoor air into circulation to keep low the concentrations of contaminants from cleaning products, paints, perfumes, people, smoking, textiles and construction material off-gassing. Other engineers design non-toxic cleaning supplies and paints, improved air filters and carbon monoxide detectors.
