The advanced IB Biology class enjoyed a day of learning with the Huntsman Marine Science Centre. It was a beautiful day to be on the rocky shore of the Passamaquoddy Bay. Saint John High students went on a three-hour expedition to explore the abiotic and biotic factors that affect life on the Atlantic Rocky Shore. Greyhounds determined elevation profiles for different parts of the shore. They also looked at quadrats to determine present coverage of seaweeds and the number of individual organisms that live there. We found Green Crabs (Carcinus maenas), side swimmers (Gammerus sp.), common periwinkle (Littorina littorea) and more.

In the afternoon we moved into the laboratory and performed two experiments with barnacles(Balanus balenoides), sea urchins (Strongylocentrotus droebachiensis) and seastars (Asterias rubens). It was a long day, filled with fun and us finally arrived home at 7:30!
