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 interactive module explores how different animals — elephants, birds, and bats — have evolved distinct ways of using sound to communicate.

This activity guides the analysis of a published scientific figure from a study that tested how bats use echolocation to adjust their hunting behavior.

This activity explores images of bats with an infectious fungal disease, which serve as phenomena for learning about population dynamics and disease impacts.

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 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 activity explores the concepts and research presented in the short film Out of the Ashes: Dawn of the Age of Mammals, which explores how life on Earth recovered after a major asteroid impact.

This activity explores images of stickleback fish, some with spines and some without spines, which serve as phenomena for learning about gene regulation and natural selection.

This animation shows how glycolysis converts glucose into pyruvate through a series of enzyme reactions. It is the first of six animations about cellular respiration.

This animation shows two examples of how the cell uses energy from ATP. It is the sixth of six animations about cellular respiration.

This animation shows how the pyruvate dehydrogenase enzyme complex converts pyruvate into acetyl-CoA. It is the second of six animations about cellular respiration.

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

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

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

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

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.
