Earth is a unique place to live. Being just the right size and distance from the sun to maintain life is remarkable! Life depends on non-life in order to live. Explore the interdependence of living and nonliving things in ecosystems with this dynamic science e-book. Fifth-grade readers will learn about the definition of life, the importance of soil, the nitrogen and oxygen cycles, and more through this high-interest informational text filled with vibrant photographs. Aligned to the Next Generation Science Standards, a hands-on "Think Like a Scientist" lab activity and a "Your Turn" page at the end of the e-book support STEM Education and provide young scientists with an opportunity to apply what they've learned in the text. Helpful diagrams and text features, such as a glossary and index, are also included to reinforce content-area literacy and improve close reading.
