Mass Lab Station # 1

Claim: Mass did not change when the wool was pulled apart.

Evidence: We measured the wool before we pulled it apart. Recorded the mass in grams which was 167.99 grams. Then pulled the wool apart recorded the mass again which was 167.99. It was the same. The entire class had no change in mass. The wool particles didn't change because nothing had been added or subtracted. It was pulled apart but all of it was still weighed.
Reasoning: The prediction was the mass would not change and that was the result. Even though the wool was pulled apart the mass did not change, either did the particles. The scale proved the nothing changed.
