THIS LESSON WAS REVISED ON JANUARY 11, 2018. Here is a link to the previous version.
In this lesson, students are introduced to acids, a group of substances with a reputation for being reactive. In the activity, Acid Test, students discover two ways to detect acids: they use baking soda, which fizzes when mixed with acids, or a special liquid that changes color when mixed with acids. Then, students use those methods to identify common foods that are acidic.
