A Moon StoryA Moon StoryAnna said, "I think the Earth would show phases, but it wouldn't move across the sky."

Kedric said, "I don't think we would see phases of the Earth, but it would move in the sky. It would take about a month to cross it.”

Emalee said, "I think we would see the Earth move just as fast across the sky as the Moon moves across our sky when we are home on Earth. We would be able to see phases.”

Tanner said, " I have a different idea. The Earth would take about two weeks to cross the sky, and it would always be full, or almost full."
