Every time you eat a sandwich, an apple, or a piece of cake, it's like you are eating a little piece of sunshine! The sun is the source of all energy on Earth and flows through all life—even through the waste of an organism. From microscopic creatures living under your couch to gigantic elephants roaming Earth, explore the interdependence of all organisms in this fact-filled science book. Fifth-grade readers will learn all about our amazing sun, fusing elements, photosynthesis, energy exchange in ecosystems, 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 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.
