Red Tattoo

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.

Coloration in Vertebrates

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

Monkey Social Status and Immune Response

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.

HIV Receptors and Co-receptors

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

Understanding Variation in Human 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.

Zebrafish and Skin Color

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.

Human Skin Color: Evidence for Selection

In this case study, students use real data to propose hypotheses, make predictions, and justify claims with evidence, as an exploration of concepts presented in the short film The Biology of Skin Color.

Activity for The Biology of Skin Color

This activity explores the evidence that differences in human skin color are adaptations to varying intensity of UV light, as discussed in the short film The Biology of Skin Color.

Activity for The Origin of Birds

This activity explores the concepts and research presented in the short film Great Transitions: The Origin of Birds, including key fossil discoveries that reveal the evolutionary relationships between birds and theropod dinosaurs.

Activity for Your Inner Fish

This activity explores the content and research presented in the documentary film series Your Inner Fish, which describes major transitions in the evolution of vertebrate animals, including humans.
