Author Keltie Thomas and illustrator Greg Hall team up to look at hockey in a new way: from the perspective of science. Their book explores the all-important science of explosive moves (the slapshot) and maximizing a player's chance of scoring; the science of speedy, powerful skating; the puck, stick, mask, and other equipment; the properties of ice and how skating surfaces are maintained; and the science of fitness and healing injuries. How Hockey Works includes personal stories from the inspirational (the stunning careers of Bobby Orr and Wayne Gretzky) to the hilarious (the puck's origins as an India rubber ball reshaped by a frustrated rink owner). Informative sidebars, a Rules and Regs section, and a glossary help make any reader an expert on the game. From casual to obsessed every hockey fan can find something in 'How Hockey Works.' AGES: 8-12
