Describes work, machines, friction, wheels and axles, and gears in everyday surroundings, and presents experiments that explain how they work.

Text and illustrations describe the simple machines of wheels and axles.

Describes experiments involving simple machines that follow the scientific method, and can be completed in an hour or less. Explore using levers to control motion and lift, and how the steepness of inclined planes affects the force needed to move something. Most experiments also include ideas for science fair projects.

Examines the ancient origins of the wheel and explores the many inventions, from the spinning wheel to the phonograph, made possible by the simple machine.

The cave walls rumble. The ground shakes. These cars have power!

Presents several science experiments and project ideas, covering physics concepts involving gravity, friction, and laws of motion using physics and bicycles, skateboards, and roller skates.

Defines wheels and axles and shows how they are used in everyday life.

This title discusses the rides that resembled Ferris wheels that have been around for hundreds of years. Readers will learn that that the first and only true Ferris wheel was built by George Ferris Jr. for the 1893 World's Columbian Exposition in Chicago, Illinois. Today's Ferris wheels are even bigger, better, and bolder. Aligned to Common Core Standards and correlated to state standards. Abdo Kids Jumbo is an imprint of Abdo Kids, a division of...
