Why Two Heads?

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

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.

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.  

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.
