Exploring Biomass Pyramids

This interactive module allows students to collect and analyze data from a virtual river to construct biomass and energy pyramids.

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.

Exploring Trophic Cascades

This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.

CSI Wildlife

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

Sampling and Normal Distribution

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

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.

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.

Cardiology Virtual Lab

This interactive, modular lab explores the tools that doctors use to examine and diagnose patients with heart conditions.
