In this card activity, students investigate the functions of major digestive organs.

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 Click & Learn, students explore the process of digestion and how it connects to metabolism and cellular respiration. 

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

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 the bobtail squid, which serve as phenomena for learning about symbiosis and interspecies interactions.

This interactive module explores how mutations arise in germline and somatic cells. It also shows how these mutations can lead to genetic conditions, such as cystic fibrosis and cancer.

Several questions are embedded within the short film The Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture, which explores the genetics of lactase persistence and evolution of the trait in some human populations.

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 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.

This animation shows how disrupting cellular processes in the intestines can lead to colon cancer.

This animation shows how the cancer treatment Gleevec inhibits the cancer-causing protein BCR-ABL.
