In this Click & Learn, students explore factors that contribute to patterns seen in the Keeling Curve: a continuous record of atmospheric CO₂ starting in 1958.

This film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years.

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 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.

This animation shows how a region of the brain called the cerebral cortex develops in a human fetus.

This video shows a technique used to obtain detailed images of nerve cells by fluorescent microscopy.

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.
