In this card activity, students investigate the functions of major digestive organs.

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 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).

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.

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.

In this activity, students evaluate and discuss statements about the evolutionary relationship between milk consumption and lactose tolerance discussed in the short film Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture.

In this activity, students simulate a lactose tolerance test, similar to the one shown in the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, to determine which samples contain the lactase enzyme.

This activity explores the content and research presented in the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which describes a case of recent human evolution influenced by cultural factors.
