This film explores four decades of research on the evolution of Galápagos finches, which has illuminated how species form and diversify.

These two activities allow students to analyze a data set of measurements taken from two populations of Galápagos finches. The activities support concepts covered in the short film The Beak of the Finch.

This interactive simulation allows students to graph and analyze sample distributions taken from a normally distributed population.

This activity guides the analysis of a published scientific figure from a study that investigated evolutionary changes in seed-eating finches after a drought.

This interactive module allows students to explore concepts related to speciation by identifying which birds belong to one of two finch species.

In this activity, students use the built-in functions in Excel or Google Sheets to calculate the mean and median. Students apply what they learned to a dataset beak measurements of Galapágos finches.

This video case study explores whether elephants can detect, interpret, and respond to signals delivered by underground vibrations.

This activity guides the analysis of a published scientific figure from a study that explored the evolutionary origins of parasitic beetles that mimic army ants.

In this activity, students build a paper model of DNA and use their model to explore key structural features of the DNA double helix. This activity can be used to complement the short film The Double Helix.

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 herbivore populations are regulated in the Serengeti.

This activity explores images of anole lizards subjected to strong winds, which serve as phenomena for learning about natural selection and the impacts of extreme climate events.

This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.

This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest.

In this activity, students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time.

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 film explores the hypothesis that different tones of skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.

This film explores four decades of research on the evolution of Galápagos finches, which has illuminated how species form and diversify.
