Mars—our mysterious red neighbor in space. Developing readers learn key features about Mars in this low-level search-and-find beginning reader. Scientists have been studying Mars for many years. It is one of the most explored planets, right after Earth. Early readers discover new vocabulary about Mar's geography, such as the tallest volcano in the solar system and what makes the dirt look red, and the latest rover to land there. A search-and-find feature reinforces new concepts to build reading success while close-up images captivate young astronomers. A great early STEM book to inspire science learning for kindergartners and first graders.
