"One night, Alice and Oliver are surprised to find that the Moon has an odd reddish color instead of its normal bright shine. What they are seeing is a lunar eclipse. In this engaging book, they'll explore exclipses, the Moon's phases, how its gravity affects the Earth, man's visit to the Moon, and more. Fun activities at the back of the book reinforce the information and let kids test what they've learned. Includes a helpful parent's guide too."--back cover.
