Mass Lab Station #1

For this station, we had to measure a piece of fiber in a glass beaker. After recording that data, we pulled the fiber apart and measured the mass again. I claimed that the mass would not change because nothing should have left the system. The evidence I have to support this is the graph that everyone's data is on; they are all relatively close to each other and most mass' are the same after being pulled apart. The reasoning I have is that the histogram proves that the mass didn't change and in the cases where the mass did change, human error and/or scale error are factors in this. Mass doesn't change, so if nothing was put in or taken out of the system, the mass should be the same as it was when you started.
