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 explores content presented in the animated video Solving Crimes with the Necrobiome, which describes the microbial changes associated with decomposing corpses.

This activity explores an image of tattoo ink particles inside cells, which serves as a phenomenon for learning about the structure and color of human skin.

This activity explores images of animals with a mutation that affects coloration, which serve as phenomena for learning about skin color genetics and evolution.

This activity guides the analysis of a published scientific figure from a study on how social status affects the expression of genes involved in immune system processes.

This activity explores the content presented in the animated video How Tube Worms Survive at Hydrothermal Vents, which tells the story of the symbiotic relationship between the giant tube worm and chemosynthetic bacteria.

This activity analyzes a published scientific figure from a study assessing if the microbiota from a mother affects the immune systems of the developing offspring.

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 demonstration models the first step of the HIV life cycle: the binding of HIV envelope proteins to receptors on human helper T cells.

In this activity, students explore how experimental work in zebrafish led to a better understanding of the role of the gene SLC24A5 in human skin color. The activity complements the film The Biology of Skin Color.

In this activity, students extend the concepts covered in the short film The Biology of Skin Color through the application of models and mathematical thinking to explain how genomic variation and human ancestry can explain differences in skin color, a polygenic trait.

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).
