A dozen fourth- and fifth-grade Girl Scouts splash in the shade-dappled shallows of Rock Creek, southwest of Corvallis, trying to scoop up tiny aquatic insects with small dip nets and deposit them into plastic dish tubs.
They’re learning about their watershed—and getting a taste of what it’s like to be a scientist—thanks to Oregon Sea Grant’s StreamWebs program. The statewide program provides educators with field equipment, data sheets, lesson plans and training so they can teach students how to collect data about the health of waterways. It also provides an online database where students can enter and analyze the information they gathered.
“What’s special about StreamWebs is it’s a way for teachers to extend students’ field experience into the classroom,” said the program’s coordinator, Renee O’Neill.
Between August 2014 and July 2015, more than 350 students participated in the program and more than 70 educators were trained on how to use the resources that StreamWebs provides, O’Neill said. During that same period, StreamWebs loaned scientific testing equipment 650 times to educators, she said.
The equipment, contained in plastic totes, can be checked out online and picked up from the Oregon Sea Grant (OSG) office in Corvallis or the Hatfield Marine Science Center in Newport. Each tote—called a kit—addresses specific learning objectives. There’s a kit with equipment to measure the temperature, pH, turbidity and dissolved oxygen of water. There’s another with measuring tapes, ropes and soil augers so kids can document the vegetation in a designated space and characterize the soil along riparian areas. Tubs of rubber boots and clipboards can even be checked out. Lesson plans and handouts for recording data are available on the StreamWebs website, as are two new videos produced by OSG that show how to use the kits for studying water quality and macroinvertebrates.
The kit the girls at Rock Creek are using is the one for collecting macroinvertebrates, such as caddisflies, mayflies, crayfish, snails and water striders. The girls are being instructed by Guillermo Giannico, a fish ecology and watershed specialist with OSG Extension and a researcher with Oregon State University’s Department of Fisheries and Wildlife. They bring their catch to a card table Giannico has propped among the streambank rocks, and use hand lenses and an identification sheet to name what they’ve caught. “I got a stonefly nymph,” one girl exclaims, pointing at the tiny animal’s distinctive tail appendages—and then: “I got another stonefly! I am the queen of stoneflies!”
Once back at a computer, students can upload their findings onto the StreamWebs website so that they and others—including the public—can analyze the health of various watersheds over time.
“The site makes it more like doing real-life science,” said Emmet Whittaker, a science teacher at Lebanon High School who uses StreamWebs in his classroom. “[Students] see how the data can be used over time [and] how they can be shared with other scientists.”
On the website, an interactive map of the state pinpoints where data have been collected. For example, clicking on the pinpoint for D River shows that students at Taft High School in Lincoln City recorded an average pH of 5.9 on Nov. 18, 2014, and 6.76 on May 23, 2016. Site names are also listed alphabetically from Agate Beach to the Zigzag River. Since the program’s inception, 850 people have created accounts on the website, O’Neill said. Between August 2015 and July 2016, about 120 people contributed data, 503 data sheets were uploaded, and 41 new locations were entered, she said.
