Read and find out about the wind--what causes it, how it can be used to help us, and how it affects the weather--in this colorfully illustrated nonfiction picture book. Air is always moving. We can't see air moving, though we can watch it push clouds across the sky, or shake the leaves of a tree. We call moving air the wind. In this clear and appealing science book for early elementary age kids, both at home and in the classroom, Arthur Dorros shows how to make your own weather vane, and in simple terms, with playful illustrations, he explains just what makes the wind that blows all around us. This is a Level 2 Let's-Read-and-Find-Out, which means the book explores more challenging concepts for children in the primary grades.
