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 guides the analysis of a published scientific figure from a study that explored the evolutionary origins of parasitic beetles that mimic army ants.

In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment.

This activity explores images of anole lizards subjected to strong winds, which serve as phenomena for learning about natural selection and the impacts of extreme climate events.

This activity guides the analysis of a published scientific figure from a study that investigated how anole lizards may adapt to extremely cold temperatures.

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 hands-on activity allows students to analyze DNA sequences of Ebola viruses. Students use these sequences to track the virus’s spread during the 2013–2016 Ebola outbreak in West Africa.

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

This activity analyzes a figure showing the atmospheric carbon dioxide concentration from 1958 to 2023.

This activity allows students to use authentic scientific data to make claims about the threat of coral bleaching for reefs around the world.

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.
