You can't breathe underwater, but a fish can. You can't eat underwater, but a fish does it every day. Named a Best Children's Science Book of the Year by Science Books & Films, this Level 1 Let's-Read-and-Find-Out picture book explains how a fish's body is perfectly designed for life in water. Now rebranded with a new cover look, this classic picture book features graceful text that invites young readers to imagine what it's like to have gills, fins, and scales. Simple, fun diagrams help explain concepts like how fish use their gills to breathe underwater. This book also includes an additional activity for kids to set up their very own goldfish bowl. Both text and artwork were vetted for accuracy by Dr. Valerie Chase, formerly of the National Aquarium in Baltimore, and Raymond Klinger and Ernest Tresselt of Huntington Creek Fisheries. This is a Level 1 Let's-Read-and-Find-Out, which means the book explores introductory concepts perfect for children in the primary grades and supports the Common Core Learning Standards and Next Generation Science 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.
