Bridges! Amazing Structures to Design, Build & Test

Bridges! Amazing Structures to Design, Build & Test (A Kaleidoscope Kids Book) by Carol A. Johmann and Elizabeth J. Rieth

Build bridges of your design — from the "workhorse" truss-beam bridge to the dazzling suspension bridge! Use bridge-building basics, and, along the way, discover how science and creativity come together in the creation of those weight-bearing wonders — bridges!

You'll get to choose the best bridge design for different sites; make decisions about cost, safety, materials, and the environment; build and innovate using available materials; and test your construction for function and load.

Test the options! — Make an arch, Roman-style; test the strength of triangles versus squares; play bridge tug-of-war to feel push, pull, and balance in action; see how shallow arches function in raging rivers.

Solve the problems! — Build a cofferdam; make pozzolana-style cement; discover how waterproof caissons work; design a bridge to cross wide expanses; build the ideal movable birdge to handle tall ships; brainstorm about bridge fatigue.

Design and build your own! — Make a real outdoor hanging bridge; spin some cable; build a weight-bearing truss-beam bridge; hang a soaring suspension bridge; make a double-bascule movable bridge; create a cantilever; fashion a covered bridge!

Build a bridge to the future! — Imagine new materials, new technologies, and new ideas — with plenty of new challenges.
