Earth turns so the stars seem to move. Some stars only shine for a few hours each night. The star must have burned up. Some stars move faster than others.
I gave my students this multiple choice question: Melinda looked out of her window one night and saw a very bright star just over the top of a tree. Late that night she looked out and the star was gone. Which BEST explains what happened?

Only one answer is correct among these 4 choices:
- Earth turns so the stars seem to move.
- Some stars only shine for a few hours each night.
- The star must have burned up.
- Some stars move faster than others.

Could you tell me which one is correct?
