We decided to graph the data we collected on on our stars and the distance from the Earth as a class, and found some really great data to support the physical models we built. After looking for trends, we saw the following relationships develop: 1. The farther away a star is, the smaller it appears (we specifically measured the diameter, and not the circumference because we were using paper plates, not spheres like stars tend to be). 2. The closer a star is to the Earth, the larger it appears. |
All this made us think back to our mystery sun video from the anchoring lesson. And we agreed that we had figured out that the reason why we see the sun in the video is because it's the closest star to the Earth.
What we still don't know is why this particular location doesn't experience night (and we know what causes night), and just this past week, a group a students recognized the moon in the sky during morning pick-up. We also looked at the video again and noticed we never seen the moon during that video.
This got us thinking about answering all our questions about the moon that we asked on our DQB, which included:
1. Why do we see the moon at night?
2. W hy do we see the moon during the day?
3. What makes the moon appear to change?
Our next focus will be on the moon, since we've got reason to believe that if we figure stuff out about the Earth and the Moon here in Chicago, we can hopefully explain some stuff about the lack of the moon at wherever this location is in the video!
