Pretty good science book, I'd consider reading for my Kindergarten class, probably more for older kids. A couple things make me cringe, though - a picture of the new moon on a totally dark night (it has to be near the sun) and the statement that the orbit sometimes is aligned on the same plane as the earth's orbit around the sun (the moon's orbit is tilted 5 degrees relative to the earth's orbit of the sun, it stays nearly constant, the moon will cross the earth-sun orbit, that's when eclipses happen.
