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

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

In this activity, learners explore watercraft engineering and sailing.

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

In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

This lesson focuses on graphene and its electrical properties and applications.

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 explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

In this activity, learners explore the engineering behind life vests or personal flotation devices and the challenges met by these devices.

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 are asked to examine the differences between two materials in a pair.

In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.

This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.
