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

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.

Several questions are embedded within the short film The Day the Mesozoic Died, which tells the story of the scientific quest to explain one of the greatest, long-standing scientific mysteries: the sudden disappearance of the dinosaurs at the end of the Cretaceous period.

This interactive module explores how scientists use the scientific process to learn about the distant past of humans.

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

This interactive module shows how DNA sequences can be used to infer evolutionary relationships among organisms and represent them as phylogenetic trees.

This interactive module allows students to compare the morphological characteristics of seashells and construct an evolutionary tree.

This interactive, modular lab explores the techniques used to make transgenic flies and demonstrates how these flies can be used to study gene expression.
