The sun -- it melts icicles, dries grass after a rain and turns grapes into raisins. But what is the sun? And how does it transform the world around us? This informational picture book and flap book in one invites children to explore their world with delight. Each spread poses a question about the sun that is answered under the flap, where young readers will find explanations about the science of the sun and related topics. They will discover how the sun makes shadows, why water sparkles in the sun, how the sun helps make rainbows and much more. Using simple concepts of science, the Exploring the Elements series answers children's questions about wind, sun, rain and snow, and encourages young readers to explore their surroundings anew. Worlds of knowledge are waiting under the flaps!
