In this phenomenon-driven activity, students investigate how cells are signaled to make melanin and explain how mutations in melanin pathway proteins affect the coat color of various organisms.

This interactive module introduces the anatomy of the immune system and walks through the timeline of a typical immune response.

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.

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

This activity explores images of the bobtail squid, which serve as phenomena for learning about symbiosis and interspecies interactions.

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

A number of questions are embedded within the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

This activity explores an image of early embryonic cells, which serves as a phenomenon for learning about cell division and development.

This interactive module explores the circulatory systems of major vertebrate groups to gain insights into their evolution.

This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. The module also shows how mutations in genes that encode cell cycle regulators can lead to the development of cancer.

These two hands-on activities engage students in exploring the genetic basis of cancer using cards and posters.

This video provides an overview of the types of genes that, when mutated, can lead to the development of cancer.
