Laval Liberty - Day 3

Yesterday morning the students were divided into two groups, with one doing a lab to determine if temperature affects the feeding rate of barnacles and the others seeing if size affects the flipping rate of sea stars and sea urchins (echinoderms).  The students studying the echinoderms also did some drawings of the anatomy, labelling important features including the tube feet, madreporite, primary spines, and mouth.

After a yummy lunch the group headed out to Holey Point, a beach close to the Huntsman campus, to conduct the zonation lab.  Each group of four students gathered data on the animals and seaweeds running along their transect that went from the top of the beach to the low tide mark.  In the evening the students analysed their data and put it in to a graphic poster.  We are interested to see their creative posters this evening!
