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

This Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.

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

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

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.

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.

This model shows the structure of dengue virus, which causes dengue fever.

This model shows the structure of Nodamura virus, a type of nodavirus.

This model shows the structure of rhinovirus, which causes the common cold.

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

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.
