"Once again the Let's-Read-and-Find-Out-about Science series takes on a really difficult concept and dramatizes it with hands-on examples from everyday life... The explanations are clear with a simple, informal text for the new reader, and the lively line-and-watercolor pictures bring in humor and common sense." - Booklist

"Familiar scenarios and items make the concepts understandable. Also, the predictable word patterns and pictures that are tied to the text aid comprehension for the youngest reader... This book is especially recommended for teachers who are looking for appropriate nonfiction books for primary-age children. Parents will find it interesting and useful as a supplementing to the science curriculum." - Association of Children's Literature
