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 guides the analysis of a published scientific figure from a study that investigated genetic factors contributing to skin color differences, particularly within African populations.

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 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 activity guides the analysis of a published scientific figure from a study that used SNP genotyping to identify genes involved in autism.

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 analyzes a figure showing the atmospheric carbon dioxide concentration from 1958 to 2023.

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.

The activity introduces students to the concept of biomes, using Gorongosa National Park as a case study. Part of the activity involves exploring the Gorongosa National Park Interactive Map.

In this activity, students explore single nucleotide polymorphisms (SNPs) that are associated with different traits in dogs to identify genes associated with those traits.

This activity guides students through building a conceptual model of how carbon dioxide affects Earth’s climate.
