Watershed Watchdogs:
Assessing Water Quality
Unit Summary:
Students will determine a Water Quality Index of a National Park’s stream using nine physical or chemical parameters. Prior to the field study students use the Internet to research information about their local watershed. Students will also familiarize themselves with each parameter by practicing water quality testing on their own school’s drinking water. After the field study students analyze and report their real-time data, reflect on their park experience, and assess their group’s performance. Finally students use their knowledge and comprehension in an interactive game of polluting, then cleaning, a model of a waterway. Students are encouraged to use their field experience to engage in a service project such as joining a local stream monitoring groups to examine the health of area streams.
