This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.

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.

The added information provided at pause points within the animation How We Get Our Skin Color allows for a richer exploration of the topic of human skin structure and function.

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 animation describes how skin color is generated by skin cells as protection against ultraviolet (UV) radiation.

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

This animation shows how a single species can give rise to many different species with distinct traits, using anole lizards as an example.

This interactive module allows students to explore concepts related to speciation by identifying which birds belong to one of two finch species.

This film explores four decades of research on the evolution of Galápagos finches, which has illuminated how species form and diversify.

This film explores the adaptation of anole lizards (genus Anolis) to habitats common across the islands of the Caribbean. The anoles are excellent examples of adaptive radiation, convergent evolution, and speciation through reproductive isolation.

This animation shows how HIV infects a cell and replicates itself using reverse transcriptase.

This animation shows how the protein MECP2 helps switch off gene expression.
