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

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. Suggested level: primary.
Explains how and why ramps and other inclined planes are used in everyday life.
Introduces six simple machines, describing how they work in more complex machinery and how they are used every day.
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.
Clear definitions supported by everyday examples and easy hands-on activities introduce young scientists to wedges.
