The article provides instructions for a biology laboratory experiment, which was designed for high school biology classrooms. The experiment is based on the work of Elie Metchnikoff, who discovered phagocytosis, a process where cells absorb materials by “swallowing” it with their membrane. In the experiment that is described, biology students attempt to measure the pH of the digestive compartment in Paramecia by using pH indicators.
