Step-by-step explanation:

Purpose

To learn the proper use of a meterstick, vernier caliper, micrometer, and electronic scale, and to

learn how to use the correct number of significant figures in data and results.

Equipment

Meterstick, 2-meterstick, vernier caliper, micrometer, laboratory balance, ruler, metal cylinder.

Discussion

The number of significant figures in a measurement depends on the measuring device and its

precision. When an object is measured in a same manner, a vernier caliper has a greater precision

than a meterstick and a micrometer has a greater precision than a vernier caliper. A measurement

reading should have one more significant figure than the smallest subdivision marked on the scale.
