This is the stuff of Mr. McGregor, science teacher to all three grade eight classes. Students were required to build a vessel that would, first of all, float, and secondly, accept weight and still float.
The weight came in the form of marbles added to the vessel as it sat in the liquid. The more successfully constructed the vessel, the more marbles it would be able to hold.
Pictured above are two teams in the heat of scientific competition. Natalie Doering and Brittany Smith watch as Kelly Boudreau and Molly Helferty plop marbles into their entrant vessel.
