Crescent School - Day 4

On this beautiful day the Crescent boys headed over to Ministers Island for the morning.  The island is special because it can be reached by foot or car at low tide by a sand bar and also because it was the summer home of Sir William Van Horne, who was the driving force in the completion of the railway across the western part of Canada.  The group toured Covenhoven, the bath house, and the gigantic barn.

During the afternoon the students spent time in the lab learning about echinoderms.  They studied the patterns on an urchin under the microscope, tested the strength of the urchin tube feet, and determined if size effects the flipping rate of sea stars.

Their last activity before departing for the airport was to release back into the ocean all of the animals that were collected and studied all week.  Thank you and safe travels!
