What Is a Gas?

Children's Literature - Hazel Buys

Concepts that describe the basic physics of gases are explained in five to fifteen-word sentences that define what a gas is and what it is not. The properties of a gas are also described. The first page introduces matter, and a series of introductory pages put a gas within the larger context of matter. Colorful photographs of young children and adults accompany the descriptions of each characteristic of a gas. Two pages at the end of the book explain the oxygen cycle in photosynthesis and respiration. A list of six facts about gases follows, with a glossary and an index concluding the book. This book is part of the "First Step Nonfiction States of Matter" series and would be a good addition to a preschool and/or early elementary science program.
