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

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

In this activity, learners explore how the hull shape impacts a ship's performance and stability.

Using simple, inexpensive items, learners build and test submarine models.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.
