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.

CSI Wildlife

This interactive module allows students to use DNA profiling and related biological concepts to solve two cases of elephant poaching.


This video describes the technology of metabarcoding, which allows scientists to determine herbivore diets based on the sequences of plant DNA extracted from animal dung.

The Geologic Carbon Cycle

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

DNA Sequence Assembly

This tutorial describes the principles of DNA sequencing and sequence assembly, and shows how they apply to different sequencing techniques.

Virochip DNA Microarray

This tutorial describes how DNA microarrays called Virochips are designed to detect known viruses and discover new ones.

Sanger Sequencing

This animation illustrates Sanger sequencing, one of the earliest methods used to sequence DNA.

Shotgun Sequencing

This animation illustrates shotgun sequencing, a method that was used to sequence the human genome.

Triplet Code

This animation describes how many nucleotides encode a single amino acid, which is a key part of the genetic code.
