This is a wonderful book. It tell students all about science and how the earth works. I would read this to some older students so they can comprehend everything that's in it.

This book teaches kids about the water cycle and the air cycle. It shows them how water travels from the oceans to the clouds and back to the earth as rain. it also shows them how air is made of many different gases, and that we need oxygen to survive. it describes the earth as our own space shuttle, and I like this analogy.
