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.

In this inquiry-based activity, students engage in science practices to figure out why some people with a genetic condition that usually leads to sickle cell disease do not have disease symptoms.
 

This activity guides the analysis of a published scientific figure from a study that investigated how gene duplication contributed to the evolution of electric fish.

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

This video describes how scientists silence different genes in regenerating planaria to study the process of regeneration at the molecular level.

This activity analyzes a published scientific figure from a study that investigated the biological importance of sleep. In this study, scientists tested whether sleep plays a role in removing harmful substances from the brain.

This activity guides the analysis of a published scientific figure from a study that investigated how random mutations during cell division can contribute to cancer.

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

This animation shows how a region of the brain called the cerebral cortex develops in a human fetus.

This video shows a technique used to obtain detailed images of nerve cells by fluorescent microscopy.

This film explores how gene duplications and mutations have led to remarkable physiological adaptations in Antarctic fish.

This activity explores the research presented in the short film The Making of the Fittest: The Birth and Death of Genes, which illustrates how gene duplications and mutations have allowed some fish to adapt to extreme environments.
