Mystery of the Missing Tusks

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.

Stalking the Genetic Basis of a Trait

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.

Cell Division and Cancer Risk

This activity guides the analysis of a published scientific figure from a study that investigated how random mutations during cell division can contribute to cancer.

Selective Breeding in Maize

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).

The Teosinte Hypothesis

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.

Mapping Genes to Traits in Dogs Using SNPs

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

Earth Systems Activity

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

Molecular Genetics of Color Mutations in Rock Pocket Mice

In these activities, students transcribe and translate portions of the rock pocket mouse Mc1r gene to further explore the genetic variations responsible for different coat colors as described in the short film Making of the Fittest: Natural Selection and Adaptation.
