This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

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 environmental engineers might approach solving the problem of an oil spill.

In this activity, learners explore how engineers incorporate biometric technologies into products as well as the challenges of engineers who must weigh privacy, security and other issues when designin

In this activity, learners explore how musical instruments are engineered.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

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

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

In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

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

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity, learners explore how rescue devices are designed to aid professionals during emergency situations.

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 design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.

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