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.

This activity guides the analysis of a published scientific figure from a study that investigated genetic factors contributing to skin color differences, particularly within African populations.

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 guides the analysis of a published scientific figure from a study that used SNP genotyping to identify genes involved in autism.

In this activity, students explore single nucleotide polymorphisms (SNPs) that are associated with different traits in dogs to identify genes associated with those traits.

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

In this activity, students explore the phenomenon of convergent evolution presented in the short film The Origin of Species: Lizards in an Evolutionary Tree. They build and interpret phylogenetic trees to infer how certain adaptations evolved among the Anole lizard populations of the Caribbean.

This activity explores the concepts and research on the anole lizards discussed in the short film The Origin of Species: Lizards in an Evolutionary Tree, including adaptation by natural selection, convergent evolution, and the formation of new species.

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.
