Aces Wade into Watershed at Mill Creek Park

Students in Lower Merion High School’s AP Environmental Science classes recently traded textbooks for test kits as they ventured into Mill Creek Park for a day of field research. The outing, part of a curriculum extension made possible through a dynamic partnership with the Lower Merion Conservancy, gave students the chance to apply classroom knowledge to real-world environmental science.

Guided by Conservancy educators, students conducted chemical tests and macroinvertebrate surveys—standard methods used by professionals to assess the health of aquatic ecosystems. Equipped with waders and collection nets, they examined dissolved oxygen levels, nitrate and phosphate concentrations, pH and water temperature, while also collecting macroinvertebrates whose populations serve as biological indicators of water quality.

Prior to the trip, Conservancy staff visited classrooms to deliver a primer on the Mill Creek watershed, highlighting local pollution challenges and potential solutions. The hands-on experience not only enriched students' understanding of ecological systems but also fostered a deeper connection to their community’s natural resources.
