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.
In this inquiry-based activity, students engage in science practices to figure out ways environmental factors drive the natural selection and adaptation of Galápagos finches.
The added information provided at pause points within the animation Coral Bleaching allows for a richer exploration of coral reefs, symbiosis, and other topics in biology.
This activity explores images of anole lizards subjected to strong winds, which serve as phenomena for learning about natural selection and the impacts of extreme climate events.
This activity guides the analysis of a published scientific figure from a study that investigated how anole lizards may adapt to extremely cold temperatures.
This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.
This activity guides the analysis of a published scientific figure from a study on how adversity in early life impacts the long-term survival of baboons.
This interactive module explores the biology of sex determination and development in humans, set against the backdrop of the different sex testing policies implemented throughout sports history.
This activity explores the content presented in the animated video Nature’s Cutest Symbiosis: The Bobtail Squid, which describes how the light produced by bacteria living inside bobtail squid helps the squid avoid its predators.
