by Trudee Romanek and Pat Cupples
Framed by a story about an inquisitive girl on a quest to understand advanced technology, this book explains the remarkable workings of devices that permeate everyday life. Topics range from lasers in grocery scanners to infrared beams in fire alarms. Readers will discover how optical fibers in an endoscope bend light so doctors can see inside people's stomachs and how radio waves heat food in microwave ovens by reacting with water molecules. Romanek and Cupples provide a fascinating introduction to technology that's appropriate for children ages 8 to 12.
