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.
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.
This video describes the work of biologists Steve Palumbi and Megan Morikawa, who use field and controlled experiments to understand the mechanisms that allow some corals to tolerate a greater amount of heat stress than other corals.
In this video, biologist Ken Dial demonstrates that birds use their wings for more than just flying, which may help us understand how dinosaurs used their small wing-like limbs before the evolution of flight.
In this video, ecologist Brian Silliman explains how he uses manipulative field experiments to study salt marsh ecosystems. His approach revealed that these systems are under top-down control from consumers and predators.
