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

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

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

This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.

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

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.

A number of questions are embedded within the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

This interactive module explores the circulatory systems of major vertebrate groups to gain insights into their evolution.

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