pulleys

Science buffs will find the topics that pique their curiosity in this book that spans the science spectrum, including simple machines, elements, computers, and sound, electrical, and light energy. Fun, easy projects demonstrate key concepts, while quizzes test reading comprehension.

Describes work, machines, gravity, friction, and pulleys in everyday surroundings, and presents experiments that explain how they work.

Uses the principles of makerspaces to introduce the pulley. Simple text describes the structure and uses of pulleys, and clear, step-by-step instructions show children how to make their own for creative projects.

"Presents information on simple machines with a focus on pulleys. Explains what a pulley is, how pulleys work, and includes examples of past and present uses. Intended for third to fifth grade students"--Provided by publisher.

An exploration of pulleys, covering how they are used, their design, how they work, and more.

"Is it easier to lift a bag full of toys with an inclined plane or a pulley? Readers will see how a group of kids compares two simple machines and decides which one does a better job."--Provided by Publisher.

"How do the Imagineers make elephants fly? Actually, it's simple machines, that is! Here, the Imagineers give a new look at how levers and pulleys were utilized to create attractions such as Dumbo the Flying Elephant and Soarin' Over California. See how levers and pulleys make work easier by either multiplying or redirecting the effort we put into them. Identify the two forces involved in using a machine and learn to calculate mechanical advantage, given effort and resistance"--Container.

Simple text and color photographs depict examples of pulleys in daily life and how they work.

"A hands-on approach introduces young scientists to pulleys. Science theory and practical, fun projects teach the physics and the technology behind this simple machine. Important science curriculum is explained through historical and contemporary examples of pulleys. Step-by-step projects range from the simple to the more challenging"--Provided by publisher.

Text and photographs showcase pulleys, from how they work and their various uses in daily life, to the two different types of pulleys.
