In this lesson, students learn more about the concept of air quality. They are guided to boost their IAQ, or indoor air quality, via a presentation that first introduces key factors that influence indoor air quality and then covers ways to improve indoor air quality. Students apply what they've learned by participating in a sensory activity to experience how quickly a smell can travel through the air. Then they work in teams to brainstorm ways they can use their senses to detect problems in air quality and come up with solutions to boost IAQ.
