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

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 engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

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

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 ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

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

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

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

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

In this activity, learners investigate passive solar building design with a focus solely on heating.

Learners develop an understanding of air pressure in two different activities.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

Learners construct an electricity-generating wind turbine out of a plastic bottle.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from
