Winogradsky Column: Microbial Ecology in a Bottle

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.

Population Dynamics

This interactive simulation allows students to explore two classic mathematical models that describe how populations change over time: the exponential and logistic growth models.

How Animals Use Sound to Communicate

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

Sampling and Normal Distribution

This interactive simulation allows students to graph and analyze sample distributions taken from a normally distributed population.

Vertebrate Circulatorium

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


This interactive module allows students to explore the science of Earth's deep history, from its formation 4.5 billion years ago to modern times.

Symbiotic Bioluminescence

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

Bacterial Quorum Sensing

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.

Neurophysiology Virtual Lab

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