Lizards in Hurricanes

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.

Lizards in the Cold

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

Testosterone Levels in Elite Athletes

This activity guides the analysis of a published scientific figure from a study that compared the testosterone levels of Olympic-level elite athletes.

Why Two Heads?

This activity explores images of planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

Pelvic Evolution in Sticklebacks

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.

DNA Profiling Activity

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.

Synchronized Division

This activity explores an image of early embryonic cells, which serves as a phenomenon for learning about cell division and development.

Mapping Genes to Traits in Dogs Using SNPs

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

Earth Systems Activity

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

Using DNA to Explore Lizard Phylogeny

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 Car
