Skin Color and Human Evolution

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.

Cancer Cell Invasion

This activity explores an image of tumor cells invading muscle tissue, which serves as a phenomenon for learning about cancer, mutations, and cell division.

Pelvic Evolution in Sticklebacks

This activity guides the analysis of a published scientific figure from a study that used SNP genotyping to identify the mutations that result in morphological differences in stickleback fish.

Role of p53 in the Cell Cycle

This activity analyzes a published scientific figure from a study that investigated the role of p53 in cell cycle regulation.

The Search for a Mutated Gene

This video describes the case of a patient with retinitis pigmentosa (RP), a progressive disease that leads to blindness, and how physician-scientist Dr. Ed Stone approached the search for the causal mutation.

DNA Profiling Activity

This multipart activity is designed to give students a firm understanding of genetic profiling using short tandem repeats (STRs), which is a process used by forensics labs around the world.

CSI Wildlife

This interactive module allows students to use DNA profiling and related biological concepts to solve two cases of elephant poaching.

Metabarcoding

This video describes the technology of metabarcoding, which allows scientists to determine herbivore diets based on the sequences of plant DNA extracted from animal dung.

Spreadsheet Tutorial 4: t-Test

In this activity, students explore different ways of calculating t-values and performing t-tests using built-in functions in Excel or Google Sheets. Students apply what they learned by plotting beak size measurements of Galapágos finches collected before and after a drought.
