In this card activity, students investigate the functions of major digestive organs.

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

In this Click & Learn, students explore the process of digestion and how it connects to metabolism and cellular respiration. 

In this hands-on activity, students build a paper model to explore how CRISPR-Cas9 is used to edit genes.

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.

Several questions are embedded within the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which explores the genetics of lactase persistence and evolution of the trait in some human populations.

This tutorial describes the structure and function of the cancer-causing protein BCR-ABL. It also shows how drugs targeting this protein can help treat chronic myeloid leukemia (CML), a cancer of the white blood cells.

In this activity, students evaluate and discuss statements about the evolutionary relationship between milk consumption and lactose tolerance discussed in the short film Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture.

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 activity explores the content and research presented in the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which describes a case of recent human evolution influenced by cultural factors.

This tutorial explores how fat is digested, transported, stored, and used for energy.
