Grade 7 Pond Project: Exploring Ecosystem Health Up Close

For the past few weeks, Grade 7 students ventured beyond the classroom for a hands-on scientific investigation as part of their annual Pond Project. Through a series of visits, students explored the health of the on-campus pond by conducting field tests and studying its living organisms.

To begin, students measured water quality by collecting data on temperature, dissolved oxygen, nitrates, phosphates, pH, turbidity, and conductivity, which inform on the pond's condition and human activities that might be affecting the pond. Two key indicators of a balanced aquatic environment. These metrics helped paint an initial picture of the pond’s condition.

Next, the focus shifted to biodiversity. Students searched for macroinvertebrates—small, spineless creatures visible without a microscope—as an additional way to assess ecosystem health. Their findings included water striders, leeches, pouch and orb snails, as well as dragonfly and damselfly nymphs. They also discovered animals with backbones, including frogs in various stages of development, from tadpoles to adults.

“This project gives students a real-world connection to what we study in class,” said Cathy Cirrotti, Upper School Science Teacher. “It’s a chance for them to apply scientific skills in the field, work collaboratively, and gain a deeper appreciation for the complexity and importance of local ecosystems.”

The Pond Project continues to be a memorable and meaningful experience for Grade 7, combining teamwork, outdoor exploration, and a deeper understanding of environmental science.
