Water Testing Engages Junior High Science Classes

What differences are there between water sources? Just because water looks clear, does that make it safe to drink? What are total dissolved solids?

To help answer these questions, 7th and 8th grade students from the Ambridge Area Junior High School conducted some basic water testing during their science classes, with the help of their local Water Resources Extension Educator. Sources tested included a public water supply, two different private wells, bottled water, and even water from a local stream. Students used electronic TDS and pH meters, as well as test strips for nitrates to take measurements of each of the water samples. The classes also discussed what human impacts could negatively affect drinking water sources, and changes that could be made to minimize pollution.
