Experiment #1: Linear Dimensions and Volume
Hypothesis
What method do you think will be more precise for measuring the object’s volume (a) using calipers to measure linear dimensions and then calculate the volume or (b) just measuring the volume of water displaced by the object? Why do you thing so?
Measurements
Shape of the regular-shaped object: Rectangle

The method that will be the most precise for measuring the objects volume will be the volume of water displaced by the object. Calipers cannot measure all types of shapes and objects making them more restrictive. The is also less room for error in the displacement method as measurements wont vary as much with this method.

Conclusion and Error Analysis
The purpose of this lab was to get us to think about the uncertainties and how values differ in different
scenarios. Two methods were used in this lab to determine volume. First method was to use calipers to
measure the dimensions of the object however this only works for the regular shaped object not the
irregular shape. The second method calculating the volume be seeing how much water the blocks
displace when placed in a overflow can. The values obtained by the first method have a smaller
uncertainty because the first method is more accurate in terms of its measurements. The tool used in
the first method has a much smaller instrumental uncertainty than the tools used in method two which
is why their values are slightly different in terms of it measurements. In method one, there are not
many sources of error other than the uncertainties of the measuring tool. In method two there are
sources of error. There could be more or less water displaced during measurement. To measure the
mass of the object we used a triple beam balance. The density of the objects were determined by
dividing the mass with the average volume of the object being measured.
