BRIDGES Etta Kaner Illustrated by Pat Cupples Toronto, Kids Can Press, 1994. 48pp, paper, $10.95 ISBN 1-55074-146-2. CIP Reviewed by Brenda Partridge Volume 22 Number 4 1994 September Technology is a very important part of our school curriculum in the 90s. Etta Kaner, a teacher in Mississauga and author of Balloon Science1 and Sound Science2, has created a marvellous combination of information and activities to complement units on bridges. In only forty-eight beautifully illustrated pages, students are introduced to a variety of beam, arch, suspension and movable bridges. Instructions are given for creating models and then testing their strength. Suggested materials are readily found around the home, and models can be tested with ease. Challenges to improve designs and increase strength are included. This book has been very well researched and was created with the assistance of engineers, the ministry of transportation and real bridge builders. Although a tremendous amount of information is introduced, the presentation is very non-threatening because of the large, colourful sketches, easy-to-understand language, and jokes scattered in the balanced format. Using bridges from around the world as examples, the author intersperses the architectural facts with historical information. One copy of this publication will not be enough for a library! It will appeal to teachers, students and parents for projects, classroom study and home activities. Highly recommended.
