Why Two Heads?

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

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.

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.

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.

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.

Salamander Limb Regeneration

This animation shows how salamanders can replace missing limb tissues with the help of cells similar to stem cells.

VEGF

This animation shows how tumors use the protein VEGF to recruit blood vessels.
