Northeastern University Marine Science Center instructors led Nahant Johnson Elementary School's sixth graders to three sites in Salem to investigate local water quality. The students sampled water at different areas within the Forest River Conservation Area and Salem Harbor. They measured water temperature, salinity, pH, dissolved oxygen, and turbidity, and discussed how these physical factors impact the organisms living there. Students charted and presented their findings, compared the results to their predictions, and took plankton samples back to the classroom for further analysis.
This marine science program, engaging children from Preschool through Grade 6 in both classroom-and field-based marine science learning experiences, is made possible by a grant from the Nahant Education Foundation.
