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 video explores how scientists identify which bat populations are infected with Nipah virus and could transmit the virus to humans.

This interactive module allows students to collect and analyze data from a virtual river to construct biomass and energy pyramids.

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

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

This playlist can be used to teach several core concepts in evolution and molecular biology by connecting students to actual research on the rock pocket mouse. It can be used in a general high school biology course.

This playlist can be used to teach several core concepts in genetics and molecular biology by having students collect and interpret evidence to explain the biology of lactose intolerance. It can be used in a general high school biology course.

This playlist can be used to teach several core topics in ecology by connecting students to actual research being conducted in Gorongosa National Park in Mozambique. It can be used in general high school biology and environmental science courses.

This playlist can be used to teach several core concepts of population dynamics and trophic cascades through three diverse ecological examples: wolves in Isle Royale, Michigan; rinderpest and wildebeest in Tanzania; and cougars in Zion National Park, Utah. It can be used in general biology and environmental high school courses.

This playlist can be used to teach concepts in geology and evolution using mass extinction events. It can be used in general high school biology, environmental science, and earth science courses.
