In this activity, students investigate the phenomenon of lactase persistence by making sense of a series of data sets.

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.

In this hands-on activity, students build a paper model to explore how CRISPR-Cas9 is used to edit genes.

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 investigated whether there is a correlation between a population’s diet and copies of a certain gene.

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.

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 extends concepts covered in the film Got Lactase? The Co-evolution of Genes and Culture. Students infer whether someone is likely to be lactase persistent or nonpersistent based on the data from two different tests.

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.
