Watershed Airshed Education

The health of a watershed is characterized by the water quality of its streams and rivers, its ability to support aquatic life, and the richness of native species (biodiversity). While many people understand the complex interactions between land and water, the relationship between airsheds and water quality may not be as obvious. Identifying where pollutants come from, how they are transported, and how they affect the watershed is key to helping students understand the connections between air, land, and water.

On this webpage, teachers (grades 6-12) can find lesson plans and classroom exercises to help students investigate Delaware River air and watersheds.


Classroom Activities


A Drop in the Bucket –  An exercise to show students how much their state’s water supply contributes to the world water supply and how it compares to glaciers, oceans, etc. Developed by Oklahoma State University.

Water Test Record Sheet.xls –  Sample data sheet for recording water quality data from monitoring sites, including free chlorine, total chlorine, hardness, and pH parameters.

World Water Supply –  Charts showing all the sources of water in the world and what portion is available for human use.


Lesson Plans
