This interactive video explores how two scientists tracked the 2013 Ebola outbreak in West Africa. 

This interactive module can be used to model infectious disease spread in a population. It includes background on the SIR model and two simulators for modeling disease spread on different scales. 

This interactive video explores how scientists identify which bat populations are infected with Nipah virus and could transmit the virus to humans.

This video case study explores whether elephants can detect, interpret, and respond to signals delivered by underground vibrations.

This interactive module explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.

This interactive module explores niche partitioning, a mechanism that enables similar species of animals to coexist.

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

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

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

This interactive module allows students to examine evidence from brain anatomy, tissue histology, and genetic studies to identify possible targets for the treatment of Alzheimer’s disease.

A number of questions are embedded within the short film The Origin of Species: The Beak of the Finch, which explores four decades of research on the evolution of the Galápagos finches.

This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.
