1 of 1 copy available

Playing Tug-of-War, pedaling a bike, jumping rope—these actions all require force! We typically don't notice most of the forces around us, but they surround us all the time. Find out how force works, and then harness your knowledge to design and build like an engineer! Third-grade students will enjoy learning about inertia, tension and gravity, lift and air resistance, electric and magnetic forces, combined forces, 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 is included at the end of this e-book to provide students 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 improve content-area literacy and support STEM instruction.

      Gr 3-5-Maintaining a steady balance between general concepts and specific facts, these surveys are apt to stimulate broader interest in science and nature as well as provide helpful information for elementary level reports. Some topics are trimmed to fit, while others are more detailed. Changing Matter includes plasma as the "fourth state" to solids, liquids, and gases (and features a crowd-pleasing infographic showing what happens when solid food changes to gas in the human stomach). Predict It! is a wide-ranging introduction to using the scientific method to test hypotheses, and the authors of both Photosynthesis and Gravity cleverly bring the water cycle into their purviews. Examples are well chosen for the intended audience, too. Each volume's easily digestible narrative is enhanced with a mix of photographs and cartoon images or schematics and capped with a pair of very low-overhead individual or group projects. VERDICT Both the content and the lively presentations will leave readers pleased as well as better informed.
