Today was d-day - dissection day! This morning started out with a fish dissection lab. The students studied the external anatomy of their fish to learn more about its habitat and prey. Then they opened them up! A few of the fish has eggs, while others had lots of prey in their stomach. During the lab we had some really determined students that even found the otolith bones of their fish. Not an easy task!
To enjoy the beautiful afternoon we headed to the beach to gather data on invasive green crabs and marine debris. The students found and marked 300 crabs in just over an hour. Wow! Then they did an awesome job cleaning up marine debris from a section of the shoreline.
Very focused during the fish dissection!
Wonderful drawings and observations.
