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

In this activity, learners collect, categorize, weigh and analyze classroom trash and discuss ways that engineers have helped to reduce solid waste.

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.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

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

In this activity, learners explore how watermills have helped harness energy from water through the ages.

In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

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.

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

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

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

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 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.

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.
