In this physical activity, two lines of learners link hands and arms to model a beam subject to various loading schemes.

Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.

In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.

Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

Learners explore the field of civil engineering by making a bridge using spaghetti as their primary building material.

Learners develop an understanding of air pressure in two different activities.

In this activity, learners explore work, forces, simple machines, and construction. This lesson guide includes simple ways to demonstrate these principles as well as hands-on activities.

In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.
