Read and find out about the ups and downpours of the water cycle! With colorful illustrations and engaging text, Down Comes the Rain is a fascinating look into the stages of the water cycle. After rain comes down, the sun comes out and dries the puddles. But the water isn’t gone. The heat from the sun has turned it into water vapor—it has evaporated. Eventually, this moisture in the air condenses to form new clouds. Soon the rain will fall again.Featuring rich vocabulary bolded throughout the text, this brand-new edition of Franklyn M. Branley''s 1997 title includes original illustrations by Mary Ann Fraser. This book also includes a glossary and a find out more section with an activity about the water cycle. Both the text and the artwork were newly vetted for accuracy by Don W. Hen and Dr. Sonia M Kreidenweis, Professor of Atmospheric Science at Colorado State University. This is a Level 2 Let’s-Read-and-Find-Out Science title, which means the book explores more challenging concepts for children in the primary grades and supports the Common Core Learning Standards, Next Generation Science Standards, and the Science, Technology, Engineering, and Math (STEM) standards. Let’s-Read-and-Find-Out is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.
