Build Your Own Wind Turbine
Source Institutions
Learners construct an electricity-generating wind turbine out of a plastic bottle.

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

You Can't Take It With You
Source Institutions
This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.

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.

Rooftop Gardens
How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

Wind Turbine
Source Institutions
Learners build a wind turbine and test it to see how much energy is created.

Build a Coral Polyp
Source Institutions
In this activity, learners build one or more edible coral polyps and place them together to form a colony.

Invent a Plant
Source Institutions
In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

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.

The Watershed Connection
Source Institutions
In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.

Build a Tree
Source Institutions
This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.
