Learn about the complex mechanics that come into the creation of simple machines. Discussed in the pages of this book are the six types of simple machines - screw, inclined plane, wedge, pulley, lever, wheel and axle. There will be detailed explanation of how each of these machines are created, and used to make work easier. This educational book is ideal for third graders.
What are simple machines and how do they work? In this book, we’ll take a look at some of the most commonly used simple machines with the intention of figuring out what makes them tick. You will soon realize that the mechanisms between each machine is guided by the laws of physics. Are you ready to learn? Then grab a copy today!
Everything moves! Kids run around the playground, cars drive on the road, and balls fly through the air. What causes all this motion? Physics! Forces and motion rule the way everything moves through space. In Explore Forces and Motion! With 25 Great Projects, readers ages 7 through 10 discover that the push and pull of every object on the planet and in space depends on how a force acts upon it. Things float because of a force called buoyancy, we stick to the ground because of a force called gravity, and we make footprints in sand because of a force called pressure. Physics becomes accessible and interactive through activities such as a experimenting with a water cup drop, building a bridge, and spotting magnetic field lines. Simple machines such as levers, pulleys, and wedges are used as vehicles for discovery and comprehension of the foundational concepts of physical science. Using a theme familiar to everyone—motion—this book captures the imagination and encourages young readers to push, pull, twist, turn, and spin their way to learning about forces and motion.
It's time to go to the amusement park! Giant rides loom around you, and countless parts are in motion. But many simple machines are at work too. See the Ferris wheel? That's a wheel and axle. Try your luck at skee-ball. You're using an inclined plane. Find out more about the simple machines behind the excitement.
Isaac Newton was as strange as he was intelligent. In a few short years, he made astounding discoveries in physics, astronomy, optics, and mathematics— yet never told a soul. Though isolated, snobbish, and jealous, he almost single-handedly changed the course of scientific advancement and ushered in the Enlightenment. Newton invented the refracting telescope, explained the motion of planets and comets, discovered the multicolored nature of light, and created an entirely new field of mathematical understanding: calculus. The world might have been a very different place had Netwon's theories and observations not been coaxed out of him by his colleagues. Isaac Newton and Physics for Kids paints a rich portrait of this brilliant and complex man, including 21 hands-on projects that explore the scientific concepts Newton developed and the times in which he lived. Readers will build a simple waterwheel, create a 17thcentury plague mask, track the phases of the moon, and test Newton's Three Laws of Motion using coins, a skateboard, and a model boat they construct themselves. The text includes a time line, online resources, and reading list for further study. And through it all, readers will learn how the son of a Woolsthorpe sheep farmer grew to become the most influential physicist in history.
Introduces simple machines, including screws, levers, wedges, and pulleys, describes how each makes everyday life easier, and provides activities demonstrating these machines in action.
Finalist for the 2015 AAAS / Subaru SB&F Excellence in Science Book exemplify outstanding and engaging science writing and illustration for young readers A children's instructional book on how to use readily available materials to turn the house into a science lab Physics teacher Bobby Mercer provides readers with more than 50 great hands-on experiments that can be performed for just pennies, or less. Turn a plastic cup into a pinhole camera using waxed paper, a rubber band, and a thumbtack. Build a swinging wave machine using a series of washers suspended on strings from a yardstick. Or construct your own planetarium from an empty potato chip canister, construction paper, scissors, and a pin. Each project has a materials list, detailed step-by-step instructions with illustrations, and a brief explanation of the scientific principle being demonstrated. Junk Drawer Physics also includes sidebars of fascinating physics facts, such as did you know the Eiffel Tower is six inches taller in summer than in winter because its steel structure expands in the heat? Educators and parents will find this title a handy resource to teach children about physics topics that include magnetism, electricity, force, motion, light, energy, sound, and more, and have fun at the same time.
How can something that grounds us and keeps us here on this earth be so invisible and mysterious? We’re not talking about anything abstract and undetectable. We’re talking about GRAVITY! Gravity is a force that affects everyone and everything. Gravity is something we can easily understand, even kids, especially if they have the right tools to teach them. Explore Gravity! With 25 Great Projects will introduce kids ages 6-9 to the basics of gravity, including concepts of matter, attraction, and gravitational pull. Projects include creating a working model of a scale to learn what “weight” really means and how it’s affected by gravity. By playing with various weights to make a marvelous mobile, readers learn about the center of balance and how martial artists use this knowledge to throw their weight around. All the projects in this book are easy to follow, require little adult supervision, and use commonly found household products, many from the recycling box! The fun facts, trivia, jokes, comics, and hands-on activities will help kids discover the captivating science of gravity. Furthermore, the informational text and hands-on activities will excite kids about STEM, the interrelated fields of science, technology, engineering, and math.
