All of the planets in our solar system circle around one giant ball of gases: the sun. This simple yet fascinating book explains how the sun was formed and where its energy comes from. Readers learn to identify the different parts of the sun. A hands-on activity investigates the sun's changing place in our sky, while full-color photographs and fast facts enhance the narrative. This book correlates directly with the Next Generation Science Standards' expectation for understanding Earth's Place in the Universe in first and second grades. It is also aligned with English Language Arts standards.
