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 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 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 interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.

A number of questions are embedded within the short film The Origin of Species: The Beak of the Finch, which explores four decades of research on the evolution of the Galápagos finches.

This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.
