SummaryAir pollution and poor air quality affect human health and the environment. In this unit, students explore the properties of air, and learn about the Air Quality Index (AQI). Students investigate air pollution through activities on visible and invisible air pollutants, and gain an understanding of how engineers develop and use technology to reduce and clean-up air pollution in our atmosphere.
Engineers design solutions to prevent, reduce and clean up the air pollution that affects living things and the environment. Environmental engineers must understand the composition of air and the chemical makeup of air pollutants in order to determine how to mitigate air pollution and improve poor air quality.
