Dr. David Grant, marine ecologist and Davidson College Professor Emeritus of Biology, spoke to the STEAM students about biological diversity. His presentation featured four different worms from the Cape Cod region, as well as a sea spider. These rare specimens are part of a Discovery Place collection that Dr. Grant helped create. He also showed slides from his expeditions — describing what marine ecologists do in the field. At the end, students completed a learning activity: sorting and classifying the genus Hardware.
