In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment.
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.
This activity accompanies the video Seed Dispersal and Habitat Fragmentation. Students use data from published studies to understand patterns of seed dispersal and apply these ideas to the design of a conservation area.
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.
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.
This activity guides the analysis of a published scientific figure from a study on prehistoric human food sources. In this study, scientists used carbon isotopes to determine how the advent of agriculture affected human diets.
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).
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 activity explores how scientists determined how and where corn was domesticated, as discussed in the short film Popped Secret: The Mysterious Origin of Corn.
