Air Quality Monitoring Concepts

The video tutorial covers the study of particulate matter, focusing on PM2.5, using air quality monitors. It discusses potential sources of particulate matter, such as construction sites and pollen, and provides instructions for using monitors in a lab setting. Alternative data sources like PurpleAir and EPA websites are suggested. Methods for measuring larger particles using contact paper are explained, along with practical demonstrations for observing particulate matter in a classroom environment.
