# Straw Bridges

Working as engineering teams, students design and create model beam bridges using ... (more)

Working as engineering teams, students design and create model beam bridges using plastic drinking straws and tape as their construction materials. Their goal is to build the strongest bridge with a truss pattern of their own design, while meeting the design criteria and constraints. They experiment with different geometric shapes and determine how shapes affect the strength of materials. (less)

# Stressed and Strained

Students are introduced to the concepts of stress and strain with examples ... (more)

Students are introduced to the concepts of stress and strain with examples that illustrate the characteristics and importance of these forces in our everyday lives. They explore the factors that affect stress, why engineers need to know about it, and the ways engineers describe the strength of materials. In an associated literacy activity, while learning about the stages of group formation, group dynamics and team member roles, students discover how collective action can alleviate personal feelings of stress and tension.

# Strong as the Weakest Link

To introduce the two types of stress that materials undergo compression and ... (more)

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. (less)

Students will conduct several simple lab activities to learn about the five fundamental load types that can act on structures: tension, compression, shear, bending, and torsion. In this activity, students break foam insulation blocks by applying these five fundamental load types (tension, compression, shear, bending and torsion). Students will study carefully each type of fracture pattern (break in the material) and make drawings of the fracture patterns in their notes in order to learn the telltale marks of failure due to each fundamental load type.

# Tower O' Power

In this activity, students learn about creating a design directly from a ... (more)

In this activity, students learn about creating a design directly from a CAD (computer-aided design) program. They will design a tower in CAD and manufacture the parts with a laser cutter. A competition determines the tower design with the best strength:weight ratio. Students also investigate basic structural truss concepts and stress concentrations. Partnership with a local college or manufacturing center is necessary for the completion of this project. (less)
