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 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.

This film tells the story of the ecologists who first documented the role of keystone species in ecosystem regulation.

This interactive module traces the evolutionary history of birds by comparing the bone structures of a chicken to those of other species.

This film explores the adaptation of anole lizards (genus Anolis) to habitats common across the islands of the Caribbean. The anoles are excellent examples of adaptive radiation, convergent evolution, and speciation through reproductive isolation.

This interactive module shows how DNA sequences can be used to infer evolutionary relationships among organisms and represent them as phylogenetic trees.

This interactive module allows students to compare the morphological characteristics of seashells and construct an evolutionary tree.

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 natural selection and speciation by connecting students to actual research on Caribbean anoles. It can be used in AP/IB Biology and undergraduate college courses.

This playlist can be used to teach several core topics in evolution by exploring examples of lizard species evolution and the effects of mass extinctions on tetrapod evolution. It can be used in undergraduate biology courses.

This playlist can be used in an online, undergraduate (majors-level) introductory biology lab to incorporate core topics in evolution, diversity of life, and ecology.
