Hi! I have a science project that's due today, and I need a little bit of help. I finished the actual project (look up "moon phases cup activity" if you wanna see what it was), but now I have to answer a few questions. My problem is that the questions are pretty vague, and I don't know what would be correct.

1. As you turned the inside cup to the right, what did you notice about the appearance of the “moon”?

2. What changes about the appearance of the moonas you turn the inside cup through the phases?

3. What is the limitation to this model (Hint: What is missing from this model?)

I'm really confused about this.
Thank you <3
