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

This activity guides the analysis of a published scientific figure from a study that explored how dinosaurs may have regulated their body temperatures.

This activity extends concepts covered in the film The Origin of Birds. Students analyze and interpret data from a scientific paper to explore thermoregulation in living and extinct animals, including dinosaurs.

This animation shows how disrupting cellular processes in the intestines can lead to colon cancer.

This activity guides students through building a conceptual model of how carbon dioxide affects Earth’s climate.

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.

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 film explores the genetics and evolution of lactase persistence in humans.

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

This animation shows how the PPAR-gamma receptor can activate fat storage and changes in hormone levels.

This animation shows how the protein MECP2 helps switch off gene expression.
