K-Gr 2—A particular focus on engines, wheels, and other components set these unusually informative introductions apart. Silverman steers clear of potentially intimidating terminology like "internal combustion" and "hydraulic" but describes in lucid detail how pistons drive crankshafts, fluid pressure lifts a fire ladder, friction affects speed and control, and various design elements counteract air resistance. The mix of close-ups and wider angled views on every page are both helpful and stimulating—and, as a plus, show women on a tank's crew or driving big rigs and monster trucks. Each volume closes with a labeled diagram, a set of "Fun Facts," and a relatively generous set of further resources. A poorly expressed claim in Trains that it "takes little energy to pull heavy trains because there is little friction" aside, all of the volumes merit consideration either on their own or as upgrades for relevant titles in Lerner's "Vroom! Vroom!" or "Mighty Movers" series.
VERDICT Prime material for budding gearheads and mechanics.
Each book gives a cursory overview of its titular vehicle. A simple narrative supplying brief information about purpose, engine, auxiliary equipment, and operator concludes with a catchy closing statement. Bright multicolored pages feature interesting full- and half-page photos. A diagram delineating working parts and random "Fun Facts" are appended. There are three other spring 2016 books in this series. Reading list, websites. Glos., ind. Review covers the following Lightning Bolt Books: How Vehicles Work titles: How Do Fire Trucks Work?, How Do Formula One Race Cars Work?, and How Do Tanks Work?.
