This hands-on activity supports concepts covered in the film Evolving Switches, Evolving Bodies about the evolution of stickleback fish. Students interpret molecular diagrams and build physical models of eukaryotic gene regulation.

This activity guides the analysis of a published scientific figure from a study that used SNP genotyping to identify the mutations that result in morphological differences in stickleback fish.

This film explores how mutations in gene regulatory regions have resulted in major changes in the anatomy of freshwater populations of stickleback fish.

This activity explores images of stickleback fish, some with spines and some without spines, which serve as phenomena for learning about gene regulation and natural selection.

A number of interactive questions are embedded within the short film The Making of the Fittest: Evolving Switches, Evolving Bodies, which illustrates how mutations in gene regulatory regions can result in the evolution of major anatomical features.

In this hands-on activity, students analyze the results of genetic crosses between stickleback fish with different traits. It complements the film Evolving Switches, Evolving Bodies.

In this activity, students analyze scientific figures to understand principles of island biogeography theory that determine the number of species in an isolated habitat.

This activity explores the concepts and research presented in the short film From Ants to Grizzlies: A General Rule for Saving Biodiversity, which explores the species-area relationship and its applications for conservation.

This activity guides the analysis of a published scientific figure from a study that explored habitat fragmentation and corridors in a model ecosystem. 

This activity guides the analysis of a published scientific figure from a study that explored the relationship between species number and habitat size for arthropods living on desert shrubs. 

This activity guides the analysis of a published scientific figure from a study that explored the relationship between species number and habitat isolation for arthropods living on desert shrubs. 

This film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years.

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

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

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

This interactive module explores the diversity of viruses based on structure, genome type, host range, transmission mechanism, replication cycles, and vaccine availability.

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.
