Forces can't be seen, but without them, nothing around us would happen! A force is a push or pull that usually causes movement. Friction is a force that opposes motion and slows things down or stops them. Famous scientist and mathematician Sir Isaac Newton wrote the rules about forces and motion.
Budding scientists will love learning about the properties of forces and motion by planning and carrying out investigations that explore concepts including friction, speed, and gravity.
Forces and motion are at work all around you—when you kick a ball, ride a bike, or drop a book. But what exactly are forces? And how do they make things move? For thousands of years, scientists have been testing hypotheses about forces and motion and learning from the results of their experiments. These lead to more questions: Why do you speed up when you're biking down a hill? Why are heavier objects harder to pull? Why doesn't the moon float off into space? The answers may surprise you! Find out how forces and motion are at play with everything on Earth and beyond.
Force and motion are all around us and help us move and do great things! Through a variety of vivid images and stunning facts, readers will explore how forces and motions work. The easy-to-read text and accessible glossary and index ensure that readers have the tools they need to understand such concepts as gravity, equilibrium, acceleration, deceleration, electromagnetic fields, pressure, kinetic energy, and inertia. To gain further insight into how gravity, forces, and motion works, a stimulating lab activity is featured!
The pull of gravity and the movement of Earth are just two examples of how force and motion affect every second of our lives. Help your readers explore the laws of motion and much more. Models relating to the physics of magnets, jumping on the moon, and why it's a good idea to wear a helmet while biking are some of this book's activities that leverage experiential learning to foster concept mastery.

Give your child a smart start with the revised and updated What Your First Grader Needs to Know What will your child be expected to learn in the first grade? How can you help him or her at home? How can teachers foster active, successful learning in the classroom? This book answers these all-important questions and more, offering the specific shared knowledge that hundreds of parents and teachers across the nation have agreed upon for American first graders. Featuring a new Introduction, filled with opportunities for reading aloud and fostering discussion, this first-grade volume of the acclaimed Core Knowledge Series presents the sort of knowledge and skills that should be at the core of a challenging first-grade education. Inside you’ll discover • Favorite poems—old and new, such as “The Owl and the Pussycat,” “Wynken, Blynken, and Nod,” and “Thirty Days Hath September” • Beloved stories—from many times and lands, including a selection of Aesop’s fables, “Hansel and Gretel,” “All Stories Are Anansi’s,” “The Tale of Peter Rabbit,” and more • Familiar sayings and phrases—such as “Do unto others as you would have them do unto you” and “Practice makes perfect” • World and American history and geography—take a trip down the Nile with King Tut and learn about the early days of our country, including the story of Jamestown, the Pilgrims, and the American Revolution • Visual arts—fun activities plus reproductions of masterworks by Leonardo da Vinci, Vincent van Gogh, Paul Cézanne, Georgia O’Keeffe, and others • Music—engaging introductions to great composers and music, including classical music, opera, and jazz, as well as a selection of favorite children’s songs • Math—a variety of activities to help your child learn to count, add and subtract, solve problems, recognize geometrical shapes and patterns, and learn about telling time • Science—interesting discussions of living things and their habitats, the human body, the states of matter, electricity, our solar system, and what’s inside the earth, plus stories of famous scientists such as Thomas Edison and Louis Pasteur
Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.
