This video follows scientists working in Gorongosa National Park as they try to determine the genes responsible for tusk development in elephants.

This video follows an international team of researchers as they collect data to map migratory bird populations in the US and Mexico.

This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).

This video follows biologist Elinor Karlsson, who studies dogs to find genes associated with traits, including certain diseases.

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

This interactive tool introduces students to building scientific models. Educators can use the tool to create assignments and, in some cases, automatically grade student models. 

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. 

In this Click & Learn, students explore mathematical models that describe how populations change over time and apply these models to the invasive lionfish population in the Bahamas. They also use data from other species to learn how density-dependent factors limit population size.

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

This interactive module allows students and educators to document, annotate, and reflect upon scientific research processes.

This animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.

This model shows the skull of Tiktaalik, a vertebrate that existed about 375 million years ago and had features of both fish and tetrapods (four-limbed animals).
