Milk—How Sweet Is It?

Summary

Students simulate a lactose tolerance test.

A hands-on activity in which students simulate a lactose tolerance test similar to the one shown in the film. Students will combine milk with "patients' intestinal fluid samples," which consist of either water or a lactase solution. They then measure the amount of glucose produced over time. Students will collect, analyze, and graph their data to determine which patients are lactose tolerant or lactose intolerant.
