In this phenomenon-driven activity, students investigate how cells are signaled to make melanin and explain how mutations in melanin pathway proteins affect the coat color of various organisms.

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 used SNP genotyping to identify the mutations that result in morphological differences in stickleback fish.

This activity explores images of the bobtail squid, which serve as phenomena for learning about symbiosis and interspecies interactions.

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 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.

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.

In this activity, students explore concepts covered in the short film Got Lactase? The Co-evolution of Genes and Culture about the genetic variations associated with lactose tolerance/intolerance and how the trait is inherited in families.
