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. Learners work in teams to...

In this activity, learners explore how the hull shape impacts a ship's performance and stability. Learners design, build, and test their own hull design, predict the performance of the various...

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink? Learners must adjust many variables in their boat design to maximize...

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. The activity guide contains information for Educators...

In this activity, learners design a bicycle helmet. Participants will explore the design of bicycle helmets to gain an appreciation for the role that helmet layers play protecting the head. They...

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water. Participants design, build, test and redesign their...

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle. In this simulation activity, learners create a miniature wind tunnel test by blowing air with...

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials. Great with groups or individuals, but make sure you have a "body of water" to test...
