This animation shows how a tumor forms, recruits blood vessels, and enters metastasis.

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.

These two hands-on activities engage students in exploring the genetic basis of cancer using cards and posters.

This activity explores an image of early embryonic cells, which serves as a phenomenon for learning about cell division and development.

This activity analyzes a published scientific figure from a study that investigated the role of p53 in cell cycle regulation.

This activity explores an image of tumor cells invading muscle tissue, which serves as a phenomenon for learning about cancer, mutations, and cell division.

In this inquiry-based activity, students investigate the phenomenon of fur colors in rock pocket mice to connect genotypes to phenotypes and molecular genetics to evolution. 

This activity explores images of a coral bleaching event, which serve as phenomena for learning about marine ecosystems, human impacts, and climate change. 

This activity explores the concepts and research presented in the short film From Ants to Grizzlies: A General Rule for Saving Biodiversity, which explores the species-area relationship and its applications for conservation.

In this activity, students analyze scientific figures to understand principles of island biogeography theory that determine the number of species in an isolated habitat.

This activity guides the analysis of a published scientific figure from a study that explored habitat fragmentation and corridors in a model ecosystem. 

This activity guides the analysis of a published scientific figure from a study that explored the relationship between species number and habitat size for arthropods living on desert shrubs. 

This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest.

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 interactive, modular lab explores the techniques used to identify different types of bacteria based on their DNA sequences.

This multipart animation series explores the process of photosynthesis and the structures that carry it out.

This animation shows how changes in the regulatory switch regions of a “paintbrush” gene lead to wing spot differences in Drosophila fruit flies.

This interactive, modular lab explores how the ELISA method can be used to test blood samples for evidence of certain diseases.
