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 investigated how gene duplication contributed to the evolution of electric fish.

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 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 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.

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

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 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.
