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 this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

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 demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.
