In this lesson students
will construct a boat and calcluate the water line in advance of
putting it in the water. Students will learn basic boat terms.

 The  standard
definition of floating was first recorded by

Archimedes
and goes something like this: An object in a fluid experiences
an upward force equal to the weight of the fluid
displaced by the object. So if a boat weighs 1,000
pounds (or kilograms), it will sink into the

water
until it has displaced 1,000 pounds (or kilograms) of water.
Provided that the boat displaces 1,000 pounds of water before the
whole thing is submerged, the boat floats.
