Second-graders at Miller Avenue School put their science skills into action while on a field trip to the Wading River Pond on Oct. 15.

As part of their studies on ecosystems and indigenous animals, the students were tasked with exploring the pond and its surroundings using a variety of scientific methods.

Aside from making general observations, the students tested the water for cloudiness, oxygen levels, bacteria levels and temperature in an effort to determine if the pond is healthy.
