The shovel that helps you dig a hole, the chopsticks you use at lunch, and some of the big machines we see when passing by construction sites are all examples of levers. This book takes a look at the simple machine behind these different objects, using everyday examples and kid-friendly experiments to illustrate the physics behind this fascinating simple machine. Easy-to-read text will encourage readers, while large, colorful photographs will illustrate the concepts at hand. Students will be interested to see the ways that they interact with levers on a daily basis, and further reading and websites will encourage them to seek additional information.

This book presents a program of basic studies dealing with machines and the work they do. The history of machines is presented and the six simple machines identified by scientists and examples of each are illustrated in detail. Additional topics include forces affecting objects, work and power, forms of energy, and compound machines. Each of the twelve teaching units in this book is introduced by a color transparency (print books) or PowerPoint slide (eBooks) that emphasizes the basic concept of the unit and presents questions for discussion. Reproducible student pages provide reinforcement and follow-up activities. The teaching guide offers descriptions of the basic concepts to be presented, background information, suggestions for enrichment activities, and a complete answer key.

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!
Activities explore the effects of simple machines. Lessons focus on the concepts of force, friction, gravity, and inertia. General background information, suggested activities, questions for discussion, and answers are included. Encourage students to keep completed pages in a folder or notebook for further reference and review.
