Claim: Pulling apart the wool fibers did not change the mass. Pulling something apart does not change the mass because nothing is added or taken away.
My evidence is due to the histogram we made and when comparing the data we saw that all of the results were relatively close to 0 which means there was little to no change at all. My reasoning is that nothing was added to or taken away from the particles of the wool and because pulling something apart does not change the mass because nothing is added or taken away. That is why the mass stayed the same.
