Lesson Plan

Carbon Dioxide Can Make a Solution Acidic

Can your breath change the acidity in a liquid? A lesson begins with a demonstration that proves it can. Then scholars perform an experiment to determine if other gases can change the pH of liquids. Finally, they research how this concept is changing our oceans and our planet.
