Tiny Scientists, Big Discoveries at the Kindergarten Pond Day

On Thursday, May 28, Far Hills Kindergarten students traded their classroom seats for magnifying glasses and nets as they gathered at the campus pond for the annual Kindergarten Pond Program led by educators from the Raritan Headwaters Association (RHA).

Guided by RHA educators Debbie Newcomb and Gwen Walsh, students stepped into the role of citizen scientists, exploring the pond ecosystem and discovering firsthand how even young learners can make a meaningful difference in protecting the environment.

The Pond Dip activity is part of a year-long study of animals, habitats, and ecosystems in Kindergarten science classes. Throughout the year, students have learned about species such as the bald eagle and rainbow trout, and how each plays an important role in a healthy food web supported by fresh, cold, clean water.

During the program, students investigated aquatic macroinvertebrates — tiny organisms such as insect larvae, snails, worms, and crayfish that serve as important indicators of water quality and environmental health. Using plastic spoons, cups of water, magnifying glasses, and identification keys, students carefully searched through pond and stream water samples to identify different species and calculate environmental health scores.

The class compared samples collected from the campus pond with samples brought by RHA from the nearby Peapack stream, where students later released their trout. While the stream earned a healthier environmental score — something students expected due to higher oxygen levels in moving water and the recent impact of nearby construction on the pond — the findings sparked meaningful conversations about ecosystems and conservation.

Students made exciting discoveries throughout the afternoon. In the pond, they found tadpoles, dragonfly larvae, snail eggs, a green frog, spiders, and water beetles. The stream samples revealed an even wider variety of organisms, including water pennies, caddisfly larvae, crayfish, a baby catfish, freshwater shrimp known as scuds, water striders, mayfly larvae, a whirligig beetle, and stonefly larvae.

One particularly exciting discovery was the noticeable growth in the aquatic snail population since last year’s study.

Beyond the scientific observations, the experience encouraged students to develop a deeper appreciation and respect for the natural world around them. By sharing discoveries, asking questions, and learning how scientists monitor environmental health, kindergarten students experienced how curiosity and stewardship can go hand in hand — proving that even at a young age, they can help care for the world around them.
