Conclusions I
Comment on the difference between the average density and the slope of your plot in procedure 3 and 4.
How are the different? Should they be the same? Which is the better value to use and why do you think
so?
In procedure 3 and 4 you found values for the density and uncertainty of the samples. Remembering that
the material is commonly available and has a distinct color, as shown in the video, identify the material.
Discuss how reducing the uncertainty helped in the identification.
Identify the material of the samples in procedure 5 from the same website. Remember it's a common
material with a distinct color. Explain the anomaly in the data and support your decision on how to handle
it.
