In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

Build and test a scale model of a rainforest canopy walkway.

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

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

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).

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this activity, learners explore accuracy and precision.

What's a more compelling problem to solve than being stranded on a deserted island?

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

In this activity, learners explore how engineers develop pipeline systems to transport oil, water, gas, and other materials over very long distances.

In this activity, learners explore how a hydraulic pump works. Learners work in teams to design and build a unique water fountain that employs a hydraulic pump.

In this activity, learners explore sports engineering and advanced materials development.

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

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

In this activity, learners explore how engineers work in a team to solve problems.

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.

In this activity, learners review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.

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

In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.
