Clean Air

The Clean Air Project was one of the most popular GTP projects.  Hundreds of schools monitored the air, and in this GTP project, the focus was on monitoring ground-level ozone.  We used Vistanomics innovative tool, The Ecobadge, which was a chemically sensitive paper strip that changed color in the presence of ozone.  Students could measure ozone in parts/million using the Ecobadge.
