Access Code (located on the underside of the lid of your lab kit): AC-1FVKJN
Lab Report Format Expectations
Utilize college level grammar and formatting when answering text based questions.
Report all equations in a proper mathematical format, with the correct signs and symbols.
Submissions with incomplete or improperly formatted responses may be rejected.
Pre-Lab Questions
1. The experiments in this lab utilize a number of tools to take accurate and precise measurements. One
of those instruments in the Vernier Calliper. Demonstrate what you learned regarding the use of this
tool by reading the diameter of the quarter in Figure 3 from the lab material, which has been provided
below. Your measurement must have the correct units, and must have the associated error.
Figure 3: A quarter being measured by a caliper.
d=(24.30±0.025)mm
2. Why is uncertainty crucial to the reporting of values in scientific and engineering works?
The uncertainty of the values should be added in order to indicate how accurate the
measurement really is. It depicts that the project values are not ideal. It demonstrates that we
do not pretend to know all the right answers and science gets better with time.
3. Give your own, unique example of a measurement that you have taken where you had to
consider how much uncertainty was acceptable.
