The US Bridge Challenge

Introduction

Have you ever wondered what it would be like to design and construct your own bridge?For the bridge-building activity, each group of students will be required to design, construct and test a bridge of their own creation.To begin this activity, it is first necessary to know some basics about the different types of bridges.

Procedure

Each group will gather knowledge about bridges, terms, materials and construction.

Section One:Bridge Types

In this section, you will learn about various types of bridges.Click the links to learn about the listed types.Take notes about the different types of bridges.Record your notes in your science notebook.

Types of Bridges

(Use Step 2 – Do Your Homework.Skip Step 3 – Play the Game.You’ll have a chance to play the game later.)

·Suspension

·Arch

·Beam

·Cable-stayed

·Truss

Section Two: Terminology

You’ll also need to know some terms related to bridges.Record the definitions in your science notebook.

Terms

·Piers

·Beam

·Span

Section Three: Bridge Challenge

Use your knowledge of bridge design to help the community of Craggy Rock to determine the best bridge type to use for each of their 4 locations. 

Section Four: Materials

In this section, you will perform simulated tests related to the different types of materials used to build bridges.Select each of the 8 different types of materials and perform the tests to find out more about its properties.

Be sure to read the additional information found in “Pros and Cons” and “Applications”.

Section Five: Exploration

In this section, you will have an opportunity to explore various sites related to bridge building.

Conclusion

At this point each student should have a better understanding of bridge building and design.When each group begins to design and build their bridge, it is important to understand the forces that will be affecting the bridge.Good luck!
