Activity Overview


The pH scale is used to compare different substances and identify how acidic or basic they are. A pH of 1 is a strong acid, and a pH of 14 is a strong base. If a substance has a pH of 7, it is said to be neutral (not acidic or basic). In this activity, students will demonstrate their understanding by creating their own version of the pH scale. Students will link together the strength of the acids and bases and their corresponding pH value. They should also include the colors a universal indicator turns when it is mixed in with a substance.

Alternatively, have students complete this assignment after testing different substances in the lab. Students recreate the pH scale choosing the colors they found for the different substances they tested.
