Examine how pollution makes its way into an ocean with help from a model watershed. Scholars use household items to recreate a mini-watershed, equipped with pollutants, that when mixed with rain drain into a model's body of...

Scholars investigate levels of nitrogen dioxide in the Pacific Northwest by examining the role of nitrogen in air pollution and how remote sensing can be used to measure nitrogen levels. An Excel spreadsheet calculates the difference...

Every pupil with a sweet tooth will be clamoring for this lab and analysis, particularly when they're allowed to eat the results! Volume and surface area formulas for cones are developed from models, and then extended to the printing of...

How does the Earth continually repair itself? Explore the answer to this question, and others, with a unit on plate boundaries and interaction. Pupils classify the types of movement at plate boundaries and identify the...

As part of a unit, this lesson plan familiarizes youngsters with components of a rain garden. They speculate about the role of an assigned component in contributing to a rain garden, and ultimately, in the health of the local watershed....

Forget your local meteorologist — build your own barometer and keep track of the weather with an activity that provides directions to build a barometer out of a narrow necked bottle, a glass, and some water. Using their barometer,...

Second in a pair of activities, young ecologists continue to examine the food pyramid of a freshwater ecosystem. They take a look at the food pyramid drawn in Activity A and consider what would happen if a reservoir was created on the...

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Silver: more than jewelry, it's also a natural antimicrobial agent. An inquiry-based lesson asks collaborative groups to design and implement an experiment to test this property. Using samples of silver nanoparticles and a strain of...
