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

This activity guides the analysis of a published scientific figure from a study that used SNP genotyping to identify the mutations that result in morphological differences in stickleback fish.

This multipart activity is designed to give students a firm understanding of genetic profiling using short tandem repeats (STRs), which is a process used by forensics labs around the world.

This activity guides the analysis of a published scientific figure from a study involving illegal elephant poaching. In this study, scientists used DNA profiling to determine where ivory seized from poachers had originated.

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

These two hands-on activities engage students in exploring the genetic basis of cancer using cards and posters.

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 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.

This activity allows students to calculate the mass, size, and kinetic energy of an asteroid that struck Earth 66 million years ago, based on the total abundance of iridium in a sediment layer. It supports concepts presented in the short film The Day the Mesozoic Died.
