Harbour View High Day 2

This morning the students and teachers from the Marine Biology class of Harbour View High were up bright and early to head out to Indian Point.  This mixed habitat intertidal zone presented an excellent location for the students to explore.  They found a diversity of organisms, including green crabs, a sea slug, sea cucumbers, sea stars, sea urchins, periwinkles, scale worms, sea vases, terebellid worms, and bread crumb sponge.  What a great morning on the beach!  Much better than the rain and wind storm last year!

Back in the lab the students did an experiment to test the effect of temperature change on barnacles.  I think they were surprised to see how the barnacles feed.
