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 e-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 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.
