This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).

This video follows biologist Elinor Karlsson, who studies dogs to find genes associated with traits, including certain diseases.

This interactive module consists of a virtual Winogradsky column, which can be used to explore the diversity of microbes, microbial metabolic strategies, and geochemical gradients found in sediments.

This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

A number of questions are embedded within the short film Popped Secret: The Mysterious Origin of Corn, which explores the genetic and archaeological evidence that corn was domesticated from a wild Mexican grass called teosinte.

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 film explores the genetic and archaeological evidence that suggest that corn is the result of the domestication of a wild Mexican grass called teosinte.

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

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.
