A ramp is a simple machine that makes it easier for us to move things. A ramp has a bigger distance along the slope than it has along the vertical distance. Find out all about this simple machine in this title.

Takes a look at ramps and wedges, what they are, how they are used, and how they help us.

This series offers a clear introduction to simple machines - what they are, what they're made of, and how we use them in today's world. Exciting examples of each machine's applications draw on the world familiar to a child - machines that we use all the time, including some that may be hidden in houshold objects or everyday fixtures. Amazing machine facts illustrate how we use machines to do tasks that would otherwise be difficult or impossible.

How are a water slide and a ski jump alike? Why is pushing something along a ramp much easier than lifting it in the air? Why do skis zigzag down a hill? How can a simple wedge stop an airplane? This book answers these questions and shows you how different kinds of these two simple machines are all around you to make your work and play easier.

Introduces the science of inclined planes, including ramps, wedges, and screws, describing different kinds, how they work, and jobs that they perform.

Exploring the simple mechanism of ramps and wedges. You will discover how ramps and wedges work and the wide range of tools and machines that make use of them. Large, clear photographs show the principles of ramps and wedges in practice.

Why do skiers use a zigzag path down steep slopes? How does a zipper work? How does a lock work? Ramp and wedges are simple machines that can be used to make other machines work. When you open a lock, cut something with scissors, zip up your coat, or use a doorstop you are using ramps or wedges. Ramps and Wedges explains what these machines are and how they help you do everyday things.

Uses a variety of examples, from scissors and axes to zippers and hairpin turns, to demonstrate the power of the inclined plane and show how ramps and wedges make work and play easier.

Each book in this series focuses on a type of simple mechanism and examines how it is used to make different toys work. This book examines ramps and wedges, and uses simple language and labeled photographs to explain the scientific principles behind their use.

A hands-on approach introduces young scientists to ramps and wedges. 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 ramps and wedges. Step-by-step projects range from the simple to the more challenging.
