Saint John High Gr 12 IB Bio

This weekend we have the Gr 12 IB Biology students from Saint John High School on campus. While here the students conducted a mark-recapture field study on periwinkles, gathered data on zonation patterns in the intertidal zone, had a presentation on sponges from Dr. Claire Goodwin, a researcher at a section of the Huntsman called the Atlantic Reference Centre, did an experiment to determine if size affects the flipping rate of sea stars and urchins, and designed their own behaviour lab.  It was a busy weekend!

Below are some pictures from their adventures.

Some of the animals to be identified: rough-mantled nudibranch, terebellid worm and common periwinkles.

Spicules help to identify the species of sponge.
