Anno's Sundial

School Library Journal

Gr 4 Up Anno breaks new ground by cleverly using pop-up models and sundials as experimental tools. Illustrations in subtle earth tones and unadorned text clearly explain the basic concepts of solar time, seasons, latitude and longitude, and the sundial. At the end, Anno describes how to construct a sundial that will tell time accurately. Following the sundial instructions will require some knowledge of geometry or a helpful adult. The bad news is that pop-ups often don't wear well, and Anno invites readers to mark, spread out in the grass, and trace lines on this book. Be sure to purchase extra copiesthis wonderful book should be used to pieces. Alan Newman, Johns Hopkins University, Baltimore
