These second graders have been reading books about boats and talking about how they are able to float. After some discussion, they began to design their own "boats" from aluminum foil. Each team of two boat- designers carried their creation to the tub of water and placed it in. All floated! But then quarters were added... one at a time. Whose boat could handle the "gravity" of the most quarters while remaining buoyant? There was a clear winner.
Next Step--- the why. The class continued to talk about the activity and about the features of the winning boat that made it different from the other boats.
