Lab Station #1

My claim is that when we pulled apart the fibers  of the wool the fibers split it half but then they re-closed themselves. I think the mass would weigh the same whether it was pulled apart or clumped together.
My evidence is the histogram of this lab station, which showed me that all results were close to zero which would mean little or no change. Also we need to remember that there is a 0.2 margin of error on the scale so that has to be worked in there too.
My reasoning is that  we did not add or subtract anything to the particles. That is why they stayed the same as when they were together and clumped. Also that is why the mass stayed the same.
