This Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.

This Click & Learn shows that keystone species exist across a variety of ecosystems and can exert their influence in different ways.

This video shows how a group of students, scientists, and volunteers came together to make hand sanitizer and masks for their community during the COVID-19 pandemic.

The added information provided at pause points within the animation Coral Bleaching allows for a richer exploration of coral reefs, symbiosis, and other topics in biology.

This film explores the foundational research in the Serengeti National Park, Tanzania, that uncovered many of the ecological principles that govern how animal populations and communities are regulated.

This interactive module explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.

This video describes how indigenous communities from the tropical rainforest of Darién, Panama, use drones to map their lands. The communities use these maps to protect their territories from outside incursions and to design sustainable land-use plans.

This video describes a large-scale project to restore the wildlife of Gorongosa National Park. The video highlights the project’s approach of combining traditional conservation biology with solutions for addressing challenges in the community.

This video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

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.

This video follows ecologist Mary Power, who is studying the Eel River in Northern California to decipher the connection between river flows and biodiversity.

This film tells the story of the ecologists who first documented the role of keystone species in ecosystem regulation.
