Have them raise their hands to respond. Write their ideas on the board. The worksheet includes a matching activity to reinforce vocabulary and definitions. The three math problems include solving equations and are of increasing difficulty. Assign younger students only the first question. Add the next problem for older students. Assign the third question as a math challenge to advanced students. Next time students ride in a car or bus, ask them to notice and record on paper the types of materials used in the bridges they cross. Lead a discussion of findings during the next class period.

Many types of aggregates — such as sand, gravel, pebbles, glass, vermiculite and rubber - have been used to make concrete. One disadvantage to concrete is that it is weak when a tension force is applied to it and therefore has a very low tensile strength. Concrete has a tendency to crack, and special design precautions are often taken to control the cracking. Reinforced concrete often has steel embedded in it. Why might there be so many types of aggregates?

To achieve different purposes in different applications.

Sometimes other materials are added to the concrete mix to give it specific characteristics not typical with plain concrete mixes, making the concrete less brittle, stronger, more durable, a better insulator, or less likely to suffer freeze-thaw damage. Incorporate synthetic fibers to improve elasticity, include bits of colored glass for more decorative applications, recycle glass and rubber waste material from recycling collection or old tires. Assign internet research to learn more. Lead students in another TeachEngineering activity on the strength of materials, easily relatable to concrete: Engineering for the Three Little Pigs.

Show students a blast furnace animation at the howstuffworks website: Watch a four-minute narrated film clip of the wind-induced collapse of the Tacoma Narrows Bridge in Washington in Called "Galloping Gertie," this suspension bridge collapsed four months after it was built.

The amount of compressive stress that a material can resist before failing. Today, the team at Birmingham carries out research alongside the requirements of modern structural design codes and therefore consider structural integrity, robustness and serviceability within cutting-edge research into structures and their components. The focus of ICME is placed on the materials, i. Usually, ductile materials such as steel, aluminum and other metals are used for components that experience tensile loads.

They also find out about the material properties important to bridge construction and consider the advantages and disadvantages of steel and concrete as common bridge-building materials to handle compressive and tensile forces. Engineering Connection When designing structures such as bridges, engineers carefully choose the materials by anticipating the forces the materials the structural components are expected to experience during their lifetimes.

Breaking the Mold In this math activity, students conduct a strength test using modeling clay, creating their own stress vs. Strong as the Weakest Link 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. Strong as the Weakest Link. Bridging the Gaps Students are presented with a brief history of bridges as they learn about the three main bridge types: Mechanics of Elastic Solids Students calculate stress, strain and modulus of elasticity, and learn about the typical engineering stress-strain diagram graph of an elastic material.

Mechanics of Elastic Solids. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem. Grades 6 - 8 Details View more aligned curriculum Do you agree with this alignment? Yes No Thanks for your feedback!
