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.

Synchronized Division

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

Investigating Planarian Behavior and Regeneration

This activity allows students to observe their own planarian and then design an experiment to investigate how planarians regenerate. It supports viewing of the video Identifying Key Genes in Regeneration.

Tissue Regeneration in Animals

This tutorial describes how animals differ in their abilities to heal wounds and regenerate lost body parts or damaged tissues.

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.
