Looking for a virtual option? Check out this virtual lab from PHET. Students will explore the pH of different liquids and learn about neutralization.
Alright, so now students know what pH is and how to measure it, but why is it important?
Another good topic to talk about is neutralization in the body. I usually start by telling students if I drink orange juice on an empty stomach, I will inevitably get a stomach ache. Why? Students usually recognize that orange juice is an acid and the acid is causing the belly ache. Next, I ask them what do they do when they have a stomach ache? We talk about Tums and Pepto Bismol, and how the alkaline medicine neutralizes the acid in my stomach.
