The sun is out in the day and always has a circle shape. The moon's shape seems to change and you can sometimes see it in the daytime and at night. What are the sun and the moon? How are they the same and how do they differ? Hop into your spaceship and find out! With beautiful illustrations and engaging text, The Sun and the Moon will guide young readers into a deeper understanding of their observations of the sun and the moon. Featuring a find-out-more section with instructions on how to keep an observation log and how to make moon ice, a glossary of new terms, and web research prompts, this book will begin children's explorations of the sun and the moon. Both the text and the artwork were vetted for accuracy by Bradley J. Thomson, Ph.D., Senior Research Scientist at the Boston University Center for Remote Sensing. 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, 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.
