Students at Bachman Academy in Tennessee sampled local waterways as part of the World Water Monitoring Challenge, according to the Cleveland Daily Banner. The youngsters used test kits to chart key indicators of water quality.
The monitoring kits include dissolving tablets that change color to measure pH and dissolved oxygen, as well as a cup that doubles as a sampling container and Secchi disk. Bachman students gathered samples from nearby Brymer Creek, Bachman Lake and Johnston Woods Lake.
The worldwide monitoring event begins March 22 of each year and runs to Dec. 31. School administrators say participation in the event helped students learn more about how watersheds work and the importance of protecting their local waterways.
