Michael Dahl and Denise Shea use a colorful array of pictures and colors to illustrate the use of wheels and axles. Not only does Michael Dahl thoroughly describe the wheel and axle, he also describes what belts, cranks and gears are for as well. This book is full of bright and vivid pictures that would be sure to capture a children’s eye. Also included in this book is an experiment that allows the child to fully see how a wheel and axle work.
This book is aimed students in the second, third, or fourth grade. The use of the colors and pictures could be considered a little childish yet it is highly useful when acquiring the attention of a child. When studying SOL 3.2, the teacher could begin a class with this book followed by a hands-on experiment to further educate the children on how simple machines work.
