Mass Lab Stations: Station 1

Claim: There is no change in mass if there is no change in the system.

Evidence:
            System: Beaker and fiber
            Mass Before: 167.82g
            Mass After: 167.82g
            Change in Mass: 0g
The only thing that had happened in this lab was that we pulled the fiber apart. There was no change in the system.

Reasoning: When measuring mass, if there is no change in the system, the mass will remain the same. The only way the mass will be different is if there is something added or taken out of the system.
