Product Description

Editorial Review

Young or old, amateur or pro, the architects and engineers in your life will enjoy and learn from this bridge-building kit. With it, they can build models of a steel truss road bridge (in plastic), a graceful suspension bridge (in plastic), and, coolest of all, an ancient Roman arch bridge (from build-them-yourself plaster-of-Paris blocks). They can display their favorite bridge on a 12- by 18-inch plastic molded landscape that they can decorate with the paint provided. A 48-page booklet includes not only detailed instructions but also a solid introduction to the design, history, and likely future of bridges. The booklet explores the various types of bridges (beam, truss, arch, cantilever, cable-stayed, and suspension), materials (wood, stone, brick, concrete, iron, steel, and steel cable), and forces (compression, tension, shear, and torsion) that make bridges work. --Rebecca Hughes

From Parents' Choice®

Why are there different kinds of bridges? How do they support cars or trains? How did people learn to build them? A curious child will find the answers by building models of a truss bridge, suspension bridge, and Roman arch (including molding the terra cotta stones.) The 48-page instruction manual is a model of verbal and pictorial clarity that turns the physics and history of bridge-building into an exciting adventure story. Photos of world-famous bridges, perhaps one near you, illustrate bridge-building principles. (Ruth B. Roufberg, Parent's Choice®, 1998)
