Simple Machines: Wheels, Levers, and Pulleys - David A. Adler, Anna Raff

What do the slides, flagpoles, and wheels in your life have in common? As David A. Adler explains, they’re all Simple Machines (Holiday House, $17.95). Adler relates these scientific concepts to objects and actions children see and do every day before expanding into more complex applications. The wedge is introduced via the use of teeth in chewing before Adler moves on to show the principle’s use in axes. Anna Raff’s illustrations, which emphasize the shape and movement of the different machines, tie Adler’s explanations into a wonderful package for the future tinkerer in your life. Ages 4-7.
