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.

This interactive module explores how different animals — elephants, birds, and bats — have evolved distinct ways of using sound to communicate.

Several questions are embedded within the short film The Making of the Fittest: Natural Selection and Adaptation, which uses the rock pocket mouse as a living example of natural selection.

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

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

This interactive, modular lab explores techniques for identifying and recording the electrical activities of neurons, using the leech as a model organism.
