After completing their pH scale with single examples, this activity will have students sort different substances into the three categories: Acid, Neutral, and Base. This is a great graphic organizer for students to use as a reference point for the rest of the unit.
To make this activity more challenging, have students research different substances to put in each category instead of providing them with the list included in the instructions. Encourage them to select at least seven of each and try to find ones that are less commonly known. To extend this activity, students can list the substances in order of pH from the most acidic to the most basic.
