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 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 planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

This activity explores images of plant cells and structures, which serve as phenomena for learning about how plants respond to stimuli.

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.

The activity introduces students to the concept of biomes, using Gorongosa National Park as a case study. Part of the activity involves exploring the Gorongosa National Park Interactive Map.

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.

This activity allows students to observe their own planarian and then design an experiment to investigate how planarians regenerate. It supports viewing of the video Identifying Key Genes in Regeneration.
