Empowering Educators. Inspiring Students.

This video case study explores a global effort to preserve the genetic diversity of maize (corn).

This video tells the story of how Xenopus laevis, a frog species studied by biologists around the world, was once used as a pregnancy test.

In this activity, students analyze authentic data to investigate whether there are differences in the prevalence of sickle cell trait (SCT) across different regions of Uganda.

In this activity, students explore an interactive nutrition label and interpret nutrition information for various foods.

In this activity, students use an online simulator to explore how greenhouse gases and albedo impact Earth’s energy budget and temperature.

This activity explores the concepts and research presented in the short film Out of the Ashes: Dawn of the Age of Mammals, which explores how life on Earth recovered after a major asteroid impact.

This activity guides the analysis of a published scientific figure that explores how different groups of species may shift their ranges in response to increasing temperatures.

In this activity, students analyze DNA sequences to investigate twinning in ring-tailed lemurs.

This activity guides the analysis of a published scientific figure that explores amylase gene copies and enzyme activity across mammal species.

In this activity, students analyze genetic data to figure out that sharks can reproduce asexually through a process called parthenogenesis.

In this activity, students interpret simulation data to explore how natural selection affects the percentage of the sickle cell allele in certain populations.

In this activity, students run simulations to explore how natural selection, genetic drift, and mutation may affect the frequencies of the sickle cell allele. 

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 module allows students to explore the science of Earth's deep history, from its formation 4.5 billion years ago to modern times.

This interactive module explores biomes, climate, biodiversity, and human impacts around the globe and at different times.

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

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

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