Expanding Universe Lab

In this lab we tried to visualize the way that galaxies move farther and farther away from each other. We used a balloon which represents the universe and on that balloon we put dots which represented different galaxies. We measured the distance between the dots at different stages which were when the balloon was partially filled, half filled, and fully filled. In our chart ABC had a trend which was they were all under 3. D and E were a little off from the others but those two had a trend themselves, which was that they were between 5 and 7. I enjoyed this activity because we were able to actually see how galaxies move. It helped me understand this theory more, because when we were talking about it before it was a little confusing. Can the universe stop growing? What would happen if galaxies collided?
