The group participated in several activities to investigate the biotic and abiotic factors that affect the health of the Bay. After learning to tie nautical knots, testing the harbor’s water quality, trawling (fishing with nets) and dissecting oysters they dredged, the students identified, examined and discussed the various species they found. The class wrapped up their adventure with an animated discussion about biodiversity in the aquatic ecosystem, the watershed, and restoration efforts for the health of the Bay with Chesapeake Bay Foundation representatives.
