My claim: the fiber in station 3 had the same mass before and after pulling it apart because pulling something into two pieces doesn't change the mass of it.
Evidence/ reasoning: I found the mass of the fiber before pulling it apart and it was .99 grams, then I pulled the fiber into two pieces and found the mass of both of them together again and it was still .99 grams. I think it's pretty much common sense that when you take one thing and break it into parts, you can still add them up to get the same amount you had before. Like money for example, if you have a dollar and you break it up into dimes, you still have a dollar, just a dollar in smaller pieces. That's why I think that breaking something into pieces doesn't change the mass of it.
