This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).
This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.
This activity explores an image of tumor cells invading muscle tissue, which serves as a phenomenon for learning about cancer, mutations, and cell division.
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.
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 video follows scientists studying the seeds that brown spider monkeys disperse in a tropical forest of Colombia in order to inform and improve reforestation efforts.
