In this activity, students investigate the phenomenon of lactase persistence by making sense of a series of data sets.

This activity guides the analysis of a published scientific figure from a study that investigated whether there is a correlation between a population’s diet and copies of a certain gene.

This activity extends concepts covered in the film Got Lactase? The Co-evolution of Genes and Culture. Students infer whether someone is likely to be lactase persistent or nonpersistent based on the data from two different tests.

In this activity, students simulate a lactose tolerance test, similar to the one shown in the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, to determine which samples contain the lactase enzyme.

This animation shows how human infants can digest milk using the enzyme lactase.

This interactive, modular lab explores how the ELISA method can be used to test blood samples for evidence of certain diseases.
