Bridges!

Bridges! With 25 Science Projects for Kids introduces readers ages 7 to 10 to the concepts and vocabulary of bridge construction through the lenses of history, science, engineering, math, and technology.

From the Golden Gate Bridge in San Francisco to the Tower Bridge in London, bridges are a huge part of our life. But how are these amazing structures built? What forces keep it standing? What might cause it to fall down? And who decides which type of bridge to use? In Bridges! With 25 Science Projects for Kids, readers discover how these extraordinary feats of engineering are created, and apply what they have learned to hands-on, critical-thinking activities that include building different types of bridges, such as truss, cantilever, and suspension bridges, out of different materials and modeling different types of supports. They examine the natural forces that affect structure selection and appearance, and also learn about the types of support required for each. Trivia, cartoon illustrations, links to online videos and other sources, and clear diagrams round out this book and make it fun and interesting for class discussions.
