-Define characteristics and the differences between the 7 bridge types . . . why build a suspension bridge instead of an arch bridge?
-Investigate how different bridge types hold their loads
-Evaluate the strength and stability of each bridge type through experimentation
-Determine and calculate costs involved with building a bridge
-Explore the history of each of the real world bridges
Builds seven 5'-6' long replicas of real world bridges, one per bridge type, 2 at a time. Models include replicas of Scotland's Firth of Forth Rail Bridge (cantilever), London's Tower Bridge (bascule), San Francisco's Golden Gate Bridge (suspension), the Chesapeake Bay Bridge near Virginia Beach (beam), the Astoria Bridge across the Columbia River in Oregon (truss), Australia's Sydney Harbor Bridge (arch) and the Dames Point Bridge in Jacksonville, FL (cable-stayed). The K'NEX Bridges Sets are versatile, made from reusable materials, and turn the process of using Popsicle sticks, toothpicks and glue to teach about bridges into ancient history! When a toothpick bridge fails under tension and compression, the opportunity to build on the experience and learn more is gone. With K'NEX Bridge Sets, however, students design and build bridges, test them for strength and stability, and then modify them based on points of stress and failure. All this in a matter of minutes, rather than the hours it takes for glue to dry. And K'NEX pieces can be used over and over again! Bridge building and structural design are taught routinely in elementary through college classes in the U.S. and abroad. Allows the educators great flexibility as they plan bridge or architecture curriculum with hands-on experiences for students.
Curriculum included offers key features and characteristics of each bridge type, background information and statistics on each, investigative activities and building challenges for each of the bridge types written to middle school National Standards in Science and Technology
