This four-part animation series explores the biology of the virus SARS-CoV-2, which has caused a global pandemic of the disease COVID-19.

This video shows how a group of students, scientists, and volunteers came together to make hand sanitizer and masks for their community during the COVID-19 pandemic.

This activity complements the video Virus Hunter: Monitoring Nipah Virus in Bat Populations. Students explore cases of Nipah virus infection, analyze evidence, and make calculations and predictions based on data.

This tutorial introduces students to vector-borne disease with a focus on dengue fever, which is transmitted by mosquitoes. Students also learn about strategies designed to stop the spread of disease by interfering with the mosquito life cycle.

This activity guides the analysis of a published scientific figure from a study that investigated demographic patterns in Ebola outbreaks from the Democratic Republic of the Congo.

This activity challenges students to provide their questions and ideas for experiments they could conduct to investigate the impact of releasing genetically modified mosquitoes into the wild. It accompanies the video Genetically Modified Mosquitoes.

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 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.

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

This film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years.

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 evolution of the anole lizards in the Caribbean through data collection and analysis.

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

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

This interactive module explores the diversity of viruses based on structure, genome type, host range, transmission mechanism, replication cycles, and vaccine availability.

This film explores the hypothesis that different tones of skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.
