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 investigated physiological and genetic adaptations in the Bajau, a group of people who traditionally do freediving.

This activity guides the analysis of a published scientific figure from a study that compared the testosterone levels of Olympic-level elite athletes.

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

This short video explores how a baby’s microbiome is established during birth.

This video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

This activity explores an image of early embryonic cells, which serves as a phenomenon for learning about cell division and development.

This animation shows how a region of the brain called the cerebral cortex develops in a human fetus.

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

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 film explores how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

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.
