In the hands-on activity, Enzymes Help Us Digest Food , experiments with the enzyme lactase and discussion questions help students to learn about enzyme function, enzyme specificity, and the molecular basis for lactose intolerance. Students also learn about the scientific method by interpreting evidence to test hypotheses and designing the second and third experiments to answer specific scientific questions about lactase. An alternative version of the Student Handout which gives specific instructions for all three of the experiments is provided as an attachment below.
