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 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 interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.
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 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.
