Branley's reliably clear explanations introduce the basic concept that air has weight and takes up space. Young readers are lead step by step through a demonstration as well as encouraged to observe familiar examples. Changes from the 1986 edition include new humorous illustrations and further suggestions for investigating the substance of air.

PreS-Gr 2-This newly illustrated edition of a 1986 title introduces the concept of air, its presence in our world, and its importance to the environment. The text describes several interesting facts, clearly explaining ideas and incorporating experiments that are easy to reproduce at home or in the classroom. The appealing artwork supports the narrative and takes readers on a journey through the natural world. Produced in pen and warm, earthy watercolors, the pictures are filled with amusing details. Additional, easy-to-replicate activities are appended. This book serves as a wonderful starting point for educators beginning a unit on an integral part of our ecosystem and would be an asset to any science collection.-Hope Marie Cook, Eastern Connecticut State University, Willimantic Copyright 2006 Reed Business Information.
