Provide students with real-world examples of acids and bases at a glance by displaying this bright pH scale poster in the classroom. It shows where common items fit on the scale in terms of acidity. The most acidic items, like battery acid, are found on left of the scale and more alkaline/base items, like bleach, are on the right of the scale. This poster also shows neutral items like water in the middle. The placement of items can serve as a discussion for students to understand what happens when an acid, like stomach acid, comes in contact with a base, like a stomach tablet.Display this poster in your biology or chemistry classroom to provide students with concrete examples of acidity that they may encounter in their everyday lives.
