Kevin's piles more mass on his boat as Rose watches on. His design held the most mass with 3200 g.
A sponge? A soup bowl? A food tray? A hot
glued or duct-taped contraption of straws, bottles, and cans?
All these were ideas that the physical science students
brought in when trying to make their boat float. Students
were to create a boat that would hold at least 50g of mass while
floating.

This boat design worked well, although when off balance, it took on water easily.
This boat design worked well, although when off balance, it took on water easily.
Easy, right? It was a little tougher than they had
anticipated. Students had to use the principles of buoyancy,
including surface area, even weight distribution, and method to
prevent water uptake. After all the boats had been tested,
they were evaluated for similarities and differences in achieving
the goal of floating. The plastic bottles and aluminum can
devices worked the best however it was surprising how much
something as simple as a yellow sponge or a styrofoam food tray
worked.

All the boat designs in order from most mass held to least.
All the boat designs in order from most mass held to least.
Though 50 g was the lowest level of mass that each could
hold, students added more to see who could hold the most.
Kevin's boat came in first holding 3200 g. In second
place was Anthony with 2300g, and in third was Allen with 2075.
