Lisgar & Colonel By 2018

This week on campus we welcomed students from Lisgar Collegiate Institute and Colonel By Secondary School from the Ottawa-Carleton District School Board. The students were engaged in marine biology by exploring the bay on foot and by boat. During low tide the students searched the intertidal zone for animals and seaweeds. At high tide the students gathered subtidal animals by boat or studied the specimens they collected in the lab. The students also went whale watching with Quoddy Link Marine and took an overnight trip to Grand Manan Island to explore island industries.
