Learners design their own experiment to investigate how pollution diffuses through ground material.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

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

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.
