No Stomach for It: Investigating Antacid Medication
You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.

A Study in Paper Permanence
Twelfth graders compare the permanence of papers by testing pH, determining presence of alkaline reserve as well as fold endurance, and testing lignin content.
They indicate the strength by using a starch test as a comparison.
