Children's Water Festival
Chatham Kent
Acid Rain
Overview
Students test the pH levels of various common liquids (ex: juice, vinegar). There is a brief discussion of pH and how natural habitats must have water of a certain pH in order to support plant and animal life. Students use model lakes to see which lakes are healthy and which are too acidic, due to acid precipitation. They will also discuss the dangers of high acidity to plants and animals.
