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 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).

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

In this activity, students use the website WildCam Gorongosa to gather and analyze data from trail camera photos in Gorongosa National Park. Students use this data to predict, plan, and build a biomass pyramid for species in the park.

In this activity, students further explore the short film Popped Secret: The Mysterious Origin of Corn, by working through the mathematical concepts behind George Beadle’s claim that teosinte is the wild ancestor of maize.

This video follows conservation biologist Leeanne Alonso as she surveys ant species in Gorongosa National Park to monitor the health of the park’s ecosystems.

This video follows scientists from Gorongosa National Park as they relocate zebras from a nearby reserve as part of the effort to restore healthy wildlife populations.

This animation shows how termite mounds can increase the productivity of African savanna ecosystems.

A number of questions are embedded within the short film Popped Secret: The Mysterious Origin of Corn, which explores the genetic and archaeological evidence that corn was domesticated from a wild Mexican grass called teosinte.

This animation illustrates the main stages of the water cycle in Gorongosa National Park, an ecosystem that experiences both wet and dry seasons.

This video showcases the work of mathematician-turned-biologist Corina Tarnita, who uses quantitative approaches to understand the role of termite mounds in the savanna ecosystem.

This activity explores how scientists determined how and where corn was domesticated, as discussed in the short film Popped Secret: The Mysterious Origin of Corn.
