Give students a head start in both science and organization. This unique and innovative new series pairs practical Information with useful learning tools in the form of graphic organizers. Each book features a subject pulled directly from the K-4 Earth science curriculum plus nine graphic organizers that highlight facts about each chapter topic. Venn diagrams, charts, concept webs, maps, timelines, and more are used to present facts and to show students how these tools can be used for learning. Color photographs are included to support chapter text and illustrate the topics students are reading about. Students will realize that even the hardest concepts can be broken down into pieces of Information that are easy to learn and remember. Every day the Sun appears to move in an arc from east to west across the sky. In this book, students will learn that this apparent movement is really due to the movement of Earth. They can explore how the Sun and other stars really move, and how our view of me night sky changes as Earth orbits the Sun throughout the year. Other night sky objects are discussed, including meteors and comets. A sky map of constellations and a chart of night sky objects are two of the many tools used to illustrate this important Earth science concept.
