The purpose of this experiment is to learn how use a variety of tools that will aid in the gathering of data. This data is then used to calculate different measurements including, volume and density. The experiment will also further understanding of measurement errors using the data collected.
2 – Theory
Along with the use of tools for basic
3.1-Vernier Caliper
First the Vernier Caliper (V.Caliper) was used to measure the diameter of a coin. This was done three times and the measurements as well as the average measurement are recorded in this table labeled Table 1.
Measurement 1 19.0mm Average
Measurement 2
Measurement 3

3.2-Micrometer caliper
Next the Micrometer caliper (M. Caliper) was calibrated and the zero correction was determined to be +0.020mm. The M. Caliper was then used to find the diameter of a sample of human hair and coated and uncoated optical fibers. The Zero Correction was added to all measurements and used to determine average diameters or percent differnces. The results are recorded in Table 2.
Human Hair
Coated Fiber
Uncoated Fiber
Percent Difference

3.3-Vernier and Micrometer Caliper
In this step both the V. Caliper and M. Caliper were used. The M. Caliper was used to measure the thickness of a single sheet of paper in a college physics…
