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 uses the central dogma as a model for exploring how modern molecular biology technologies can be used to treat different genetic conditions.
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 scientists and the evidence involved in one of the most important scientific quests of the 20th century: the discovery of the structure of DNA.
This interactive module shows how DNA sequences can be used to infer evolutionary relationships among organisms and represent them as phylogenetic trees.
