Read and find out about how to discover more about the air that's all around you in this colorfully illustrated nonfiction picture book.

What weighs 5 quadrillion tons but can't knock you down? Air!

The air that surrounds the earth weighs an enormous amount, but you can't even feel it unless the wind is blowing. You can't see air or smell it, either. But we know it's there, and we couldn't live without it.

When it's not windy, it can be easy to forget about air. But air is everywhere--it fills your house, your car, and even your empty milk glass. In fact, a regular room holds about 75 pounds of it!

This is a clear and appealing science book for early elementary age kids, both at home and in the classroom. It includes simple experiments that will show you how to prove that there is mysterious, miraculous air--all around you.
