LMHS students explore watersheds with Lower Merion Conservancy
LMHS students explore watersheds with Lower Merion Conservancy

As part of their exploration of the causes and effects of water pollution, students in Lower Merion High School's AP Environmental Science classes recently had the opportunity to engage in first-hand field research as an extension of the curriculum through an educational partnership with the Lower Merion Conservancy. The Aces boarded a bus and made the short trip to Mill Creek Park in Gladwyne where they learned about and performed chemical tests and macro-invertebrate bio-assessments that are used by scientists in the real world to determine the health of aquatic ecosystems.

During the field trip, students got their hands (and boots) dirty as they waded through the creek in search of various species of macro-invertebrates - the presence or absence of which provides helpful insights into the quality of the water. Students also conducted tests checking the water for its levels of dissolved oxygen, nitrate, phosphate, chloride, pH and temperature.

Prior to the field trip, representatives from the Conservancy gave an in-class presentation to students which provided an overview of the Mill Creek watershed; discussed causes of and concerns about contaminants; and proposed solutions for improving water quality. This is a great opportunity for students to learn about and discuss environmental issues within their own community as well as to gain practical experience with field research.

The Lower Merion Conservancy protects and enhances the community's character and quality of life, recognizing that the sustainable management of our environmental and historic resources is inextricably intertwined with both conservation and change. The Conservancy advocates for policies, programs and projects that support its vision for the community and builds an informed constituency that can actively support this vision.


LMSD's Strategic Plan, "All Forward," provides a framework for a collective, intentional and positive approach to change. Its five aspirational pathways guide us toward continual innovation and transformation to further educational excellence for every student. This longstanding partnership with the LM Conservancy is an example of Strategic Pathway #5: A Spirit of Community. To learn more about #LMSDAllForward and the Strategic Pathways, click here.
