Synopsis:

This entry in the "Early Bird Physics" textbook series explains what work is,

defines the simple machine under discussion, introduces special terminology

such as fulcrum, fixed pulley, friction, or axle, and shows variations on

that machine that make it more complicated. Simple hands-on activities

explore some of the properties of a pulley and illustrate ways they are

configured to increase or decrease the force needed to lift objects. A

multiracial cast of children who look to be about nine or ten are

photographed in posed situations to illustrate concepts and most of them

look realistic. Diagrams also help children see where force is applied or

what can be altered to make work easier. An endnote to adults presents

helpful discussion questions and ways to explore the vocabulary specific

to this machine while a bibliography of other books on the topic and two

generic websites suggest further exploration. A glossary and index with a

note on how to help children use these sources are added as well. All in

all these books present solid support for adults in introducing simple

machines to elementary age children.
