The Panama Canal

April 1, 2016

Gr 4-7-In a welcome change from the normal series approach, these titles place each featured structure into the context of its natural and cultural environments while discussing how it reflects the society that built it. Authors explain engineering concepts, challenges, and construction processes so clearly that readers will understand how engineers overcame seemingly impossible problems to design and build these magnificent structures. The texts include details from small-scale innovations, such as the inclusion of sticky rice in the mortar of the Great Wall to the large daunting challenges of building a bridge able to withstand the natural forces that buffet the San Francisco Bay. Illustrations are a mixture of drawings, period photos, and attractive contemporary images. VERDICT Good choice to introduce landmark structures and the engineering that made them possible.
