This afternoon I packed up some live sea stars and urchins for a visit to the grade 6 class at Vincent Massey Elementary. We had a great afternoon determining if size effects how quickly the sea stars and urchins can flip over. The students’ results showed that the smaller ones are usually faster and the sea stars are faster than the urchins. In fact some of the urchins didn’t flip at all!
We also discussed some of the methods and technologies that scientists use to research the ocean. The students studied pictures that were taken during a research cruise in the Gulf of Maine and determined the pros and cons of using a camera or campod to study biodiversity. They also learned that ROVs aren’t just used for researching biodiversity but also by industry to study the environmental conditions under aquaculture cages.
Thank you again to the great students in Mrs. Harrison’s class for a wonderful afternoon!

Students learned the madreporite (white spot) must be covered by water for the sea star to flip.
