In this card activity, students investigate the functions of major digestive organs.

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.

In this activity, students build a paper model of DNA and use their model to explore key structural features of the DNA double helix. This activity can be used to complement the short film The Double Helix.

This activity guides the analysis of a published scientific figure from a study that investigated how gene duplication contributed to the evolution of electric fish.

This activity analyzes a published scientific figure from a study that investigated the biological importance of sleep. In this study, scientists tested whether sleep plays a role in removing harmful substances from the brain.

This activity explores images of chalk formations and coccolithophores, which serve as phenomena for learning about the interactions between biological and geological processes.

The activity introduces students to the concept of biomes, using Gorongosa National Park as a case study. Part of the activity involves exploring the Gorongosa National Park Interactive Map.

This activity reinforces concepts presented in the short film The Making of a Theory. Using a map of the Malay Archipelago and information about the animals found on different islands, students discover the Wallace Line: a sharp boundary that separates distinct Asian and Australian fauna.

This activity explores the concepts and research presented in the short film Great Transitions: The Origin of Tetrapods. The film describes the discovery of Tiktaalik, a key fossil that illuminates the evolutionary history of four-legged animals.

This activity guides students through building a conceptual model of how carbon dioxide affects Earth’s climate.

This activity supports concepts covered in the film The Day the Mesozoic Died. Students will analyze geological evidence from 10 different sites around the world to predict the location of the asteroid impact that caused the mass extinction at the end of the Cretaceous Period.

This activity supports concepts covered in the short film The Day the Mesozoic Died. Students analyze graphs and data on pollen grains and fern spores to form a picture of the living landscape before and after the mass extinction that marked the end of the age of the dinosaurs.
