Everybody knows that. But what is it that pulls everything from rocks to rockets toward the center of the earth? It's gravity. Nobody can say exactly what it is, but gravity is there, pulling on everything, all the time. With the help of an adventurous scientist and his fun-loving dog, you can read and find out about this mysterious force.

This is great book to use as an opener for a science lesson on gravity. This is a picture book that tells all about what gravity is and what it does.
A good picture book, but not great.
