The purpose of this lesson is to devise a scientific investigation to detect acids and bases in common materials. In this activity, students will prepare a test solution whose color changes when an acid or a base is added. They will then determine whether various household substances are acids or bases and look for patterns in the results, determining how their test solution compares to commercial acid-base testers. Finally, they will search for other test solutions.
