Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.

In this activity, learners explore rocketry and the principals of space flight.

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

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.

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 investigate stress and strain by designing, building, and testing beams made from polymer clay.

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

In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).

In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.

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