Activity 3:  Volume of a Whale
     Each group will refer to their previous scale model of a whale and grid that picture in either one inch or one centimeter squares depending on which is more appropriate for that drawing.  Using the gridded squares and your knowledge of finding volume, the group will calculate an estimated volume of the whale as it is scaled and as it would be life-sized.  Be sure to show formulas, gridded drawing, and all procedures.  This should be accompanied by individual summaries by each team member to explain their procedures used to determine the volumes.
