I love the Jump Into Science series. The books are a great focal point for teaching children various things about out Earth and the solar system.
As with the other books, I would recommend this book for older children. It is very text-heavy with a lot of information. It does contain great pictures as well.
Of course the book is a bit outdated (lists Pluto as a planet), but it is still a great read and a great resource for teaching. There is also an experiment at the end to help teach children why we experience night and day. Awesome read.
