How does weight affect a vehicle's performance? What is transmission? How do forces affect wheeled vehicles? Build a car, make some wheels, experiment with drag, tires and bumpers using common household and classroom supplies.

How do bridges stay strong over long distances? How can bridges expand and shrink? How do different bridge designs work? With hands-on experiments using common classroom supplies (like tape, paper, cardboard, books, sand, string, and clay) this books examines trusses, suspension, abutments, piers, expansion joints and connections.

How do forces affect structures and towers? What is a foundation? How do tall structures stay strong? Readers are shown the science behind structures using real-life examples and are guided through hands-on projects and experiments to test the science concepts.
