PURPOSE The purpose of this laboratory is to become familiar with the vernier
caliper, the micrometer caliper, and the platform balance. Volume and density will
be calculated using the rules of multiplication and division of measurements.

PROCEDURE
1. Find the length, width, and thickness of the block of wood using the vernier
caliper. Record this data in the table. Determine the volume of the block using
the formula:
V = lwh (volume = length * width * thickness)

2. Find the diameter and length of the small cylinder using the micrometer. Record
this data in the table. Determine the volume of the cylinder using the formula:
 2                
V = D L (volume = * diameter * diameter * length)
4                 4

3. Find the diameter of the sphere using either the micrometer or the vernier
caliper. Record this data in the table. Determine the volume of the sphere using
the formula:
V = 4 π R3 or 0.52 D3 (volume = 0.52 * diameter * diameter * diameter) .

4. Find the mass of each of the above objects using the platform balance. Record
this data in the table.

5. Calculate the density for each object using formula:

Mass
Density =
Volume

6. List the material and the accepted value for each object. (Table B in the
appendix)

7. Find the percent of error using the formula:
Differencebetween acceptedand experimental value x 100
Percent Error =
Accepted value
