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.

Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.
