Mass Lab Station 1

In lab 1 we were suppose to measure the fiber then pull it all apart and measure it again. My prediction was  that the mass would stay the same as long as everyone put back all the fiber that they pulled apart. For the most part everyone had the same mass before and after they pulled the fiber apart. My evidence that supports this is the histogram and it said there was just a slight change but not much. The change was very small and could have been from the scale miss reading the fiber. There was no way that the mass could have changed if we put all the fiber back into the beaker because nothing was being added or taken away from the fiber. I know that my claim is correct and its telling that there was no real loss or gain in this lab station.
