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

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 tutorial describes the symbiosis between the Hawaiian bobtail squid and bioluminescent bacteria.

This tutorial describes how bacteria communicate by a process known as quorum sensing, as shown through a series of experiments involving genetically engineered bioluminescent bacteria.

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

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

This interactive, modular lab explores the techniques used to identify different types of bacteria based on their DNA sequences.
