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 Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.

This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.

This activity explores content presented in the animated video Solving Crimes with the Necrobiome, which describes the microbial changes associated with decomposing corpses.

In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment.

This activity guides the analysis of a published scientific figure from a study that investigated how gene duplication contributed to the evolution of electric fish.

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 collect and analyze data from a virtual river to construct biomass and energy pyramids.

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 short video explores the stages of decomposition of animal bodies and shows how microorganisms found during the decomposition process can provide useful information for criminal investigators.
