Why Two Heads?

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

Understanding Global Change

This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.

Genetic Mutations and Disease

This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

Thermoregulation in Dinosaurs

This activity guides the analysis of a published scientific figure from a study that explored how dinosaurs may have regulated their body temperatures.

Gorongosa's Water Cycle

This animation illustrates the main stages of the water cycle in Gorongosa National Park, an ecosystem that experiences both wet and dry seasons.

How Did Dinosaurs Regulate Body Temperature?

This activity extends concepts covered in the film The Origin of Birds. Students analyze and interpret data from a scientific paper to explore thermoregulation in living and extinct animals, including dinosaurs.  

Coral Reefs and Global Warming

This activity allows students to use authentic scientific data to make claims about the threat of coral bleaching for reefs around the world.

Synchronized Division

This activity explores an image of early embryonic cells, which serves as a phenomenon for learning about cell division and development.

Extreme Life of the Sea

In this talk, marine biologist Stephen Palumbi compares threats to biodiversity in the ocean to threats on land.

Earth Systems Activity

This activity guides students through building a conceptual model of how carbon dioxide affects Earth’s climate.

Planarian Regeneration and Stem Cells

This video discusses the remarkable regenerative capabilities of the planarian, and how biologist Alejandro Sánchez Alvarado uses them to study the biology of stem cells.
