In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this activity, learners explore the design of tall structures such as skyscrapers and telecommunication towers.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners are invited to imagine the park of their dreams!

In this activity, learners explore how boats are engineered to achieve speed.

In this design challenge activity, learners add a jet-propulsion system (i.e. a balloon) to a blimp so it flies straight and far under its own power.

In this activity, learners investigate passive solar building design with a focus solely on heating.

Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

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 activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

In this activity, learners create a working model of a nail clipper. This activity helps learners learn the basic principles of simple machines, engineering design and model building.

Build your own Mini Mini Golf Course and learn about hands-on building and design, basic circuitry, motion modules and more!

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this activity, learners explore how engineers have improved roofing designs and materials in order to protect the contents of buildings.
