Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

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

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

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 environmental health activity, learners investigate their own vital lung capacities.

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.

Water treatment on a large scale enables the supply of clean drinking water to communities.

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.
