Lab Report Format Expectations
Utilize college level grammar and professional formatting when completing this worksheet.
Report all equations in a proper mathematical format, with the correct signs and symbols.
Pre-Lab Questions
1. In this lab, you will conduct two experiments. The first will require you to take measurements
and report them in various units. The second will then require you to take measurements and
calculate a density. In your own words, describe how to calculate density.
The amount of mass that a substance contains in a specific volume is measured by its density. To
get density, you divide an object's mass by its volume.
2. Describe the difference between accuracy and precision. Why are both important in the
reporting of experimental results?
Precision describes the consistency and reproducibility of repeated measurements, whereas
accuracy describes how near an estimate is to the actual value. When reporting experimental
data, accuracy, and precision are crucial because they guarantee the validity, comparability, and
dependability of the results and aid in the making of well-informed decisions.
3. When using the metric system, what are the units used for volume, mass and distance,
respectively?
o Metric Unit of Volume: milliliter (mL), Liter (L), and cubic centimeter (cm³)
o Metric Unit of Mass: milligram (mg), Gram (g), and kilogram (kg)
o Metric Unit of Distance: Meter (m), millimeter (mm) and centimeter (cm)
