Development of Inexpensive Air Quality Monitors as a STEM Teaching Tool
Susan Ipri Brown, Engineering
For the last several years, governing bodies have encouraged introduction of STEM experiments in teaching curriculum. The air quality monitors offer a way to expose students to data collection and analysis with results that are important to the students. The air quality monitors continuously track particulate matter, CO2, temperature, and humidity in a location the students want to investigate. The students create their own hypotheses and testing protocols, then conduct the tests and analyze the results. The program has been a powerful introduction to students on collection of real time data and how air quality data is measured.
