Light is all around you! It comes in many forms: Light from the sun brightens our day, firelight flickers in the night, electric lights fill our homes—and some animals even make the sea glow!

With lively illustrations and diagrams and clear, engaging text, this Level 2 Let's-Read-and-Find-Out picture book is a fascinating look into the many ways that light brightens our world. Now rebranded with a new cover look, this book features rich vocabulary and uses simple, fun diagrams to clearly explain concepts like light speed.

This book also includes a find out more section with activities that show why plants need light to grow and why our shadows look different throughout the day. Both text and artwork were vetted for accuracy by Russell P. Leslie, Professor and Associate Director of the Lighting Research Center at the Rensselaer Polytechnic Institute.

This is a Level 2 Let's-Read-and-Find-Out, which means the book explores more challenging 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.
