This video follows scientists as they uncover the ways in which moth species in Gorongosa National Park use ultrasound to avoid being eaten by bats.

This activity guides the analysis of a published scientific figure from a study that investigated how males in a species of sexually cannibalistic spiders choose their mates.

This activity is a game that enacts the complexity of viral infections that involve different vectors and hosts.

This activity explores content presented in the animated video Solving Crimes with the Necrobiome, which describes the microbial changes associated with decomposing corpses.

This activity explores an image of a moth with unusual markings on its wings, which serves as a phenomenon for learning about mimicry and adaptation.

This activity guides the analysis of a published scientific figure from a study that modeled the impact of an infectious fungal disease on a bat population.

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

This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.

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.

In this activity, students learn about the factors that regulate the population sizes of wildebeest and buffalo in Serengeti National Park.

In this activity, students evaluate a science news article to determine whether it is a trustworthy source of information.

In this activity, students find a scientist with whom they can relate in some way and then explore and reflect upon the impact of that scientist’s work.

This interactive module explores biomes, climate, biodiversity, and human impacts around the globe and at different times.

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

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 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.

This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.

This interactive, modular lab explores the evolution of the anole lizards in the Caribbean through data collection and analysis.
