Introduces six simple machines, describing how they work in more complex machinery and how they are used every day.

"Simple Machines! introduces kids to the concept of mechanical advantage and harnesses kid-power by inviting them to build machines of their own design. This book also opens eyes and minds to the diversity of machines in their lives, and sparks the imagination with challenge, humor, and achievable projects"--Publisher.

Describes and compares the four kinds of simple machines, levers, pulleys, wheels, and ramps.

For use in schools and libraries only. Includes an assortment of activities using such simple machines as pulleys and levers.

Read and find out about six simple machines—the lever, the wheel and axle, the pulley, the ramp, the wedge, and the screw—in this colorfully illustrated nonfiction picture book. Machines help make work easier, like when you need to lift something heavy or reach way up high. Can you adjust a seesaw to lift an elephant? What happens when you combine two or more simple machines? Read and find out out in the proven winner Simple Machines! This clear and appealing science book for early elementary age kids, both at home and in the classroom, uses clear explanations and simple, fun diagrams to explain how machines work. This book also includes a glossary and a find out more section with a lever experiment. This is a Level 2 Let's-Read-and-Find-Out, which means the book explores more challenging concepts for children in the primary grades.

Reproducible activities, correlated to the National Science Education Standards, that engage students' minds as they observe, examine & investigate the concepts of force, work, power, efficiency, mechanical advantage, and ramps, wedges, levers, pulleys & gears.

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.

Introduces simple machines, including screws, levers, wedges, and pulleys, describes how each makes everyday life easier, and provides activities demonstrating these machines in action.

Give your students a kick start on learning with our Force and Motion 3-book BUNDLE. Students begin by exploring different Forces. Conduct several experiments on the force of friction and air resistance. Understand that acceleration and deceleration are examples of unbalanced forces. Next, take the mystery out of Motion. Graph the velocity of students walking home from school at different speeds. Follow directions to find your way using a treasure map. Finally, get familiar with Simple Machines. Conduct an experiment with first-class levers to study distance and force. Find the resistance force when walking up an inclined plane. Each concept is paired with hands-on activities and experiments. Aligned to the Next Generation State Standards and written to Bloom's Taxonomy and STEAM initiatives, additional crossword, word search, comprehension quiz and answer key are also included.

Building a fort in the backyard, a grandfather and granddaughter get help from six simple machines: lever, pulley, inclined plane, wheel and axle, screw, and wedge.
