Counting Using Mass

We did an activity to use mass to count the number of small objects in a handful, such as a handful of pennies, or paper clips.  This strategy is used in industry to "count" the number of stir sticks in a box of "approximately 1000".  It is used in chemistry to "count" the number of atoms in a sample of an element.
