What makes an arch strong? Why are long bridges hung from cables? How do towers stand so high? Discover the history of the world's most impressive structures, from the ancient pyramids to today's tallest skyscrapers—then explore the engineering principles at work by creating your own model structures with this set. Readers 7 to 10 can build a pyramid, colonnade, arch, dome, wind turbine, arch bridge, Eiffel Tower, skyscraper, Ferris wheel, and suspension bridge (nearly 20 inches long) using the laminated card pieces and plastic nuts and bolts provided, while reading about real-world examples in the 48-page companion book.
