Understanding Global Change

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.

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.


This interactive module explores biomes, climate, biodiversity, and human impacts around the globe and at different times.

Interactive Assessment for The Birth and Death of Genes

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.

Recent Adaptations in Humans

This tutorial describes three examples of recent human adaptations: lactose tolerance, sickle cell disease, and bitter taste perception.

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.

Symbiotic Bioluminescence

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

Using DNA to Trace Human Migration

This tutorial describes how scientists determined that all living humans originated from populations in Africa. Some of these populations migrated out of Africa less than 100,000 years ago.
