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 interactive module allows students to use DNA profiling and related biological concepts to solve two cases of elephant poaching.

This video describes the technology of metabarcoding, which allows scientists to determine herbivore diets based on the sequences of plant DNA extracted from animal dung.

This interactive module traces the evolutionary history of birds by comparing the bone structures of a chicken to those of other species.

This video explores how advances in DNA sequencing technology have improved cancer diagnosis and treatment.

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 interactive module examines Earth’s past and present climate, highlighting the effects of two important factors: solar radiation and the composition of the atmosphere.

This animation provides an overview of the greenhouse effect, a process that warms the atmosphere and surface of Earth.

This interactive module allows students to explore the science of Earth's deep history, from its formation 4.5 billion years ago to modern times.
