Empowering Educators. Inspiring Students.

This video follows biologist Shane Campbell-Staton, who is studying the adaptations that allow deer mice living at high elevations to stay warm and active during the winter.

This activity extends concepts covered in the film The Origin of Birds. Students analyze and interpret data from a scientific paper to explore thermoregulation in living and extinct animals, including dinosaurs.

This activity guides the analysis of a published scientific figure from a study that investigated physiological and genetic adaptations in the Bajau, a group of people who traditionally do freediving.

This interactive module explores how the changes in oxygen levels throughout Earth’s history have impacted the planet’s environment and types of life.

This animation shows how the enzyme complexes of the electron transport chain harvest energy from cofactor molecules to pump protons across the mitochondrial membrane and establish a chemical gradient. It is the fourth of six animations about cellular respiration.

This hands-on lab activity serves as an introduction to the film The Birth and Death of Genes. Students simulate and compare how blood pumps through the circulatory system of icefish and other fish.

In this activity, students engage in key science practices that scientists used to figure out ecosystem dynamics in the Serengeti.

This activity guides students through learning and using key scientific terms, culminating in the creation of a customizable diagram.
 

This interactive video explores how scientists identify which bat populations are infected with Nipah virus and could transmit the virus to humans.

This Click & Learn shows that keystone species exist across a variety of ecosystems and can exert their influence in different ways.

In this inquiry-based activity, students engage in science practices to figure out why some people with a genetic condition that usually leads to sickle cell disease do not have disease symptoms.
 

This activity provides three sets of cards that can be used to reflect on the nature and dimensions of science.
 

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

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 biomes, climate, biodiversity, and human impacts around the globe and at different times.

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

This film tells the story of the scientists and the evidence involved in one of the most important scientific quests of the 20th century: the discovery of the structure of DNA.
