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 video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

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.

This animated short video celebrates the early 20th-century German astronomer and atmospheric scientist Alfred Wegener, who first proposed that continents once formed a single landmass and had drifted apart.

This interactive module explores key human impacts on the environment and how they have affected Earth’s landscape, ocean, atmosphere, and biodiversity.

This video provides an overview of the types of genes that, when mutated, can lead to the development of cancer.

This animation provides an overview of some basic concepts from plate tectonics, a fundamental theory in earth science.

This video provides a demonstration of the principle of isostasy, the idea that the continental crust “floats” on the underlying mantle.

This animation explores how carbon enters the atmosphere and can be removed through a series of chemical reactions.

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.

This film explores how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

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