8th Grade Stream Survey

Eighth Grade CHESPAX Program Description

Thanks to unique geography, Calvert County has a wide variety of Biodiversity contained within it. The combination of forest, river, bay, and beach allow for plenty of different animals to rest and live here. We can test that biodiversity by employing packages of leaves that are lowered into a stream, providing a habitat for different insects and other macroinvertebrates that live in the stream.

A set of leaves put into bags resting in a stream.
Leaf packs in a backyard stream collection insects

Our eighth graders then examine the leaf packs, finding the different species that live within that environment and giving us an idea of the biodiversity of the location.
