Students will work with hands-on materials to explore how bridges function and how engineers use scientific principles to solve problems. They will experiment and learn about what bridge design is best to hold weight and which design is best to span distances and more!
Facts
Facts
Bridges experience the forces of tension and compression.
The triangle shape helps distribute force evenly and increase the strength of a bridge.
The design and materials used will determine how much weight a bridge can hold.
Different materials behave differently: some bend, some break easily, some hold more weight.
Shorter spans are typlically stronger than longer spans made out of the same materials.
Concepts
Concepts
Bridges and structures transfer and distribute force in predictable ways.
Engineers use testing and data to design bridges and other structures.
Strong structures balance the relationship between forces, materials, and design choices.
Understanding how materials behave helps engineers create stronger, more reliable bridges and structures.
Watch a video on Edpuzzle about the types of bridges.
