Observations and results Did the larger boat hull support a
greater amount of weight? Did both hulls have a similar density
right before sinking, which was roughly one gram per cubic
centimeter—the density of water? When you first put one of the
boat hulls on the water, it should float because its total
density is less than that of water. As you add pennies to the
hull, its density increases and the hull floats lower.
Eventually, when enough pennies are added, the hull's density
roughly equals the water’s. This happens right before the penny
that sinks the hull is added. The hull sinks because its density
has finally become greater than that of water. Consequently, the
hull’s density right before sinking should roughly equal the
density of water, which is one gram per cubic centimeter. Even
though the larger hull supports more weight, it also has a
greater volume, and both hulls should roughly have a density of
one gram per cubic centimeter right before sinking. (Your
densities may not have been exactly this,
