Grade 7 Students Dive Into Environmental Science at the Pond

On Friday, May 15, Grade 7 students returned to the on-campus pond as part of their annual Pond Project, an immersive, multi-week environmental science study that transforms the outdoors into a living laboratory. Through observation, data collection, and ecological analysis, students explored firsthand how scientists evaluate the health and balance of aquatic ecosystems.

Throughout the project, students worked in teams to conduct a series of field investigations designed to measure the pond’s overall water quality and biodiversity. Equipped with scientific testing tools, they collected and analyzed data on water temperature, pH levels, dissolved oxygen, nitrates, phosphates, conductivity, and turbidity. Each measurement provided important clues about the condition of the pond and the environmental factors that may influence it, including weather patterns, runoff, and human activity.

Rather than simply learning about ecosystems in a textbook, students applied the scientific method in real time—making observations, recording findings, comparing results, and discussing what their data revealed about the pond’s health. They also learned how scientists use water chemistry to determine whether an ecosystem can successfully support plant and animal life.

A major component of the project focused on biodiversity and the organisms that inhabit the pond. Students carefully searched through shallow water and vegetation to identify macroinvertebrates, small aquatic organisms that serve as important indicators of ecosystem health. Among their discoveries were water striders, leeches, orb snails, pouch snails, dragonfly nymphs, and damselfly nymphs. Students also observed vertebrates living in and around the pond, including frogs at various stages of development, from tadpoles to fully grown adults.

By identifying and studying these species, students gained a deeper understanding of food webs, habitat relationships, and how biodiversity reflects the overall stability of an environment. The presence—or absence—of certain organisms helped students draw conclusions about water quality and ecological balance.

The annual Pond Project continues to be a meaningful interdisciplinary experience for Grade 7 students, blending environmental science, teamwork, and outdoor exploration while encouraging students to think critically about conservation and the ecosystems in their own community.
