Diving Adaptations in Sea Nomads

This activity guides the analysis of a published scientific figure from a study that investigated physiological and genetic adaptations in the Bajau, a group of people who traditionally do freediving.

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.

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.

Photosynthesis

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

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.

Human Origins

This interactive module allows students to examine fossils of early humans and compare them to modern primates.

Cystic Fibrosis Mechanism and Treatment

This animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.

New Laetoli Footprints and Hominin Body Size

This activity guides the analysis of a published scientific figure from a study that used footprints formed millions of years ago to estimate the heights of early human ancestors.

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.

Patterns in the Distribution of Lactase Persistence

This activity extends concepts covered in the film Got Lactase? The Co-Evolution of Genes and Culture. Students analyze data from the scientific literature to draw conclusions about the geographic distribution of lactase persistence.

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.

Amylase Copy Number and Diet

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.
