Biodomes Engineering Design Project
In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

Straining Out the Dirt
Learners take on the role of environmental engineers as they design water filters.

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

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

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

Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

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

Low-Tech Water Filter for High-Impact Clean
Source Institutions
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.

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

For Your Eyes Only
Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Solar Water Heater
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.

Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

Let's Bag It
Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.
