Activity
DENSITY OF TOOTSIE ROLLS
PART I
Purpose: To find the density of Tootsie rolls of different sizes, compare them, and find the average
density of a Tootsie roll.
Materials: 2 different sizes of Tootsie rolls, filter paper, balance, graduated cylinder, water
Procedure:
1. Obtain 2 different sizes of Tootsie rolls.
2. Find the mass of a piece of filter paper and record it in Data Table #1.
3. Place one of the Tootsie rolls on the filter paper and find the mass. Record in Data Table #1.
4. Repeat for the second (different size) Tootsie Roll.
5. Fill a graduated cylinder with enough water that it will completely cover the Tootsie roll when it is
added to the cylinder. Record the volume in Data Table #1. (Be sure not to fill it so full that when
you add the Tootsie roll the water level goes above the markings on the graduated cylinder.)
6. Add the Tootsie roll to the graduated cylinder. Record the new volume in Data Table #1.
7. Repeat for the second (different size) Tootsie roll.
