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

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 interactive module consists of a virtual Winogradsky column, which can be used to explore the diversity of microbes, microbial metabolic strategies, and geochemical gradients found in sediments.

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

This animation explores how carbon enters the atmosphere and can be removed through a series of chemical reactions.

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

This tutorial describes the various forms of “fat” — from a tissue, to a cell type, to a class of molecules.

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