Fourth Grade Fish Dissection
Fourth graders explored the anatomy of a fish this week in the lower school science lab. Cynde McInnis from Maritime Gloucester led the dissection of Sea Perch, a local and sustainable fish. Students took note of external features, like the lateral line that can sense movement in the water, and looked at scales and pectoral fins under dissection scopes. Then, working in small groups, they dissected their specimens to locate organs like gills, liver, stomach, and heart. The highlight for many students was dissecting the eye and peering into the clear center to view the world through an upside down lens.
