The sun shines down on us, giving warmth and light. But did you know that the sun also makes the seasons? As the earth makes one complete rotation around the sun every year, the seasons on the earth change-from winter to spring to summer to fall and back to winter again. Find out how the light from the sun affects life on the earth for all living things in this look at the only star in our solar system. Now rebranded with a new cover look, this book features content-rich vocabulary, fascinating side bars and diagrams by bestselling illustrator Michael Rex, and a find out more section with a simple experiment that allows kids to make their own orbiting model with an orange and a pencil. The author, Franklyn M. Branley, was the author of over 150 science books for children and Astronomer Emeritus and former Chairman of the American Museum of Natural History-Hayden Planetarium. The text and art were vetted for accuracy by an expert in the field. 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 Science is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.
