This timeline includes key bridges and events in bridge engineering, images, links, and project references. It provides easier access for students to a more comprehensive view of bridge history, and how it forms the base of current practice and understanding of bridge analysis and design.

This activity s a student project to construct and test the load bearing capacity of a scale model bridge from toothpicks.

Survey potential bridge sites, research bridge design, and select the right bridge for the right location in this interactive activity from the NOVA Web site. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.

This hands-on lesson introduces students to the engineering design process. It connects to the story The Three Billy Goats Gruff. Students will use the design process to create a bridge that will keep the Billy Goats Gruff safe and complete the Engineering Design Process Journal.

Classroom posters with engineering and historical facts about the Bridge available for download.

1.012 introduces students to the theory, tools, and techniques of engineering design and creative problem-solving, as well as design issues and practices in civil engineering. The course includes several design cases, with an emphasis on built facilities (e.g., buildings, bridges and roads). Project design explicitly concerns technical approaches as well as consideration of the existing built environment, natural environment, economic and social factors, and expected life span. A large design case is introduced, which is used in the subsequent specialty area design subjects (1.031, 1.041, 1.051) and the capstone design subject (1.013).

In this activity, learners build bridges using paper and explore how much weight each bridge design can support. There is an element of surprise, which increases learners' interest in the physics, when they discover just how strong they can make this seemingly flimsy material. This lesson guide includes background information, discussion questions, demonstration ideas and extensions.

In this video segment adapted from NOVA scienceNOW, learn about engineering innovations that could help detect a bridge's structural weaknesses before they become dangerous.

Through the innovative use of a collection of tools, Maryland has begun identifying which of its roads and bridges are vulnerable to climate-related events.

Students design, build and test truss bridges made of straws and tape to see how much weight they can support.

To introduce the two types of stress that materials undergo compression and tension students examine compressive and tensile forces and learn about bridges and skyscrapers. They construct their own building structure using marshmallows and spaghetti to see which structure can hold the most weight. In an associated literacy activity, students explore the psychological concepts of stress and stress management, and complete a writing activity.

Poster showing two bridges, the bridge of ships "American Industry" carrying supplies to the Allies, and "Hyphen Bridge" carrying "Plots" and "Unrest" between the United States and Germany. A tiny bird comments of the former, "This is the bridge that will win the war." Title continues: American labor can either build a bridge of ships to help Pershing's army or it can permit enemy agitators to stretch the hyphen of disloyalty as a bridge to aid our enemies. Co-operation and vigorous effort will save the lives of Our Boys and bring us the right kind of Peace. We believe American wage-earners and wage-payers are loyal. Let us prove it by working together for America! Issued by the National Industrial Conservation Movement, 30 Church Street, New York City. Copies supplied on request. No. F-11.
