Mr. Ulmer's Biology classes do "Citizen Science" at our local Tulpehocken Creek Ecosystem.
The Field Studies contribute to the unit on ecology. Students study the local ecosystem and collect scientific data that is reported to the PA Fish and Boat Commission,
and the national CitSci.org web site for citizen science, and TU ( PA Trout Unlimited Stream Monitoring Program). Our work is done at three different locations along the Tulpehocken Creek: The Red Bridge Park, Cacoosing Creek at the Paper Mill, and at Grings Mill.
Students do do the following on the field studies:
1. Water Testing : conductivity, pH, temperature, dissolved solids, nitrate and phosphate
2. Macroinvertebrate Collection : Sein nets are used to collect snails, crayfish, aquatic insects, clams, and other invertebrates. These are indicators of stream health and connect to the food web concept.
3. Microscopic Inquiry : A compound digital microscope is used to observe some of the macroinvertebrates in a deep well slide. Algae and Protists have been observed. The digital images are captured on a MotiCam X digital microscope camera and displayed on a ChromeBook.
4. Fishing: Collection of fish specimens is included in our permit from the F & B Commission. Students are instructed in basic fishing techniques and regulations. Fish samples are brought back to the lab for close examination , preservation, and some for dissection. The Tulpehocken is a prime trout fishery for Southeastern PA, and is stocked with Rainbow and Brown Trout. Flyfishing is discussed and connected to the macroinvertebrate study.
5. Field Observations and Nature Walks: Students walk the trails and photograph and observe plants and animals. We have observed the following on different studies : A Bald Eagle, Osprey, Blue Heron, Muskrat, Raccoon, Broadwing Hawk, Red Tailed Hawk, Deer, bats, lichens, maosses, Sycamore and Oak Trees, and others.
6. Cross-Curricular Connections : Historical Area: Students explore the 1850s Wertz coverd bridge, the grave site of a Revolutionary soldier, the Heritage Center, the canal and locks, the Mill House, the Tully House, the 1700s Paper Mill and bridge ruins.
