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.

Virus Explorer

This interactive module explores the diversity of viruses based on structure, genome type, host range, transmission mechanism, and vaccine availability.

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.

Stopping Mosquito-Borne Disease

This tutorial introduces students to vector-borne disease with a focus on dengue fever, which is transmitted by mosquitoes. Students also learn about strategies designed to stop the spread of disease by interfering with the mosquito life cycle.

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.
