Access Code (located on the underside of the lid of your lab kit): AC-A2C8PW
Lab Report Format Expectations
Utilize college level grammar and formaṄng 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.
The diameter of the quarter is 24.05mm ±0.025mm
2. Why is uncertainty crucial to the reporting of values in scientific and engineering works
✔✔ correct answer Including uncertainty in reports is crucial because it demonstrates
how precise and accurate the measurements or calculations are. It's like admitting that all
the data that has been collected has some limits, and by mentioning these, we get a better
idea of how reliable the results really are. It's basically being honest about the potential
