In this ecology activity, learners make a model water-based ecosystem called a terraqua column. The column (in a large soda bottle) includes pond water, duckweed, sand or gravel, and small snails.

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

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

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 field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.
