Why Two Heads?
This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.
Activity for How Tube Worms Survive at Hydrothermal Vents
This activity explores the content presented in the animated video How Tube Worms Survive at Hydrothermal Vents, which tells the story of the symbiotic relationship between the giant tube worm and chemosynthetic bacteria.
Modeling Food Webs in Darién, Panama
In this activity, students use cards to build model food webs and evaluate how ecological disturbances affect each trophic level using information from the citizen science website WildCam Darién.
Stalking the Genetic Basis of a Trait
This activity supports the film Popped Secret: The Mysterious Origin of Corn. Students analyze data on the expression of the tb1 gene to explain how variations in this gene played a role in the evolution of corn.
Cell Division and Cancer Risk
This activity guides the analysis of a published scientific figure from a study that investigated how random mutations during cell division can contribute to cancer.
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.
Exploring Trophic Cascades
This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.
Activity for Some Animals are More Equal than Others
This activity explores the content and research discussed in the film Some Animals are More Equal than Others, which tells the story of the ecologists who first documented the role of keystone species in ecosystem regulation.
Selective Breeding in Maize
This activity guides the analysis of a published scientific figure from the world's longest-running controlled artificial selection study, in which scientists tested whether they could use selective breeding to change the protein concentration of maize (corn).
Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades
This film tells the story of the ecologists who first documented the role of keystone species in ecosystem regulation.
