The Stream Team uses special nets to capture tiny larvae, which are extremely sensitive to pollution. Their findings are one indicator of water quality. Some students perform tests to measure dissolved oxygen, pH levels and nitrates. Others wade into the stream with fine mesh kick nets to capture macro invertebrates, minute forms of river life, which are highly sensitive to pollutants. The presence or absence of live dragonfly and water beetle larvae is an indicator of water quality.
Students return to school with more than wet sneakers and sunburns.
Armed with a wealth of data collected at the river, they analyze and chart water quality. Over time, their reports paint a detailed picture of the health of one section of the Current River and its watershed. Lessons from the river flow into all areas of the curriculum. To share what they've learned, students write articles for their school newspaper, the Cherry Street Journal, and present public forums. These activities have led to hands-on lessons in photography, video production and desktop publishing.
