In this activity, students investigate the phenomenon of lactase persistence by making sense of a series of data sets.

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 explored inbreeding depression in a small, isolated population of wolves.

In this inquiry-based activity, students investigate the phenomenon of fur colors in rock pocket mice to connect genotypes to phenotypes and molecular genetics to evolution.

This data-driven activity accompanies the video Selection for Tuskless Elephants. It engages students in analyzing data to make evidence-based claims about the occurrence of tusklessness in elephant populations.

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

In this activity, students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time.

This activity guides the analysis of a published scientific figure from a study that explored how dinosaurs may have regulated their body temperatures.

This activity extends concepts covered in the film The Origin of Birds. Students analyze and interpret data from a scientific paper to explore thermoregulation in living and extinct animals, including dinosaurs.

In this hands-on activity, students analyze the results of genetic crosses between stickleback fish with different traits. It complements the film Evolving Switches, Evolving Bodies.

This activity explores physical and genetic evolutionary changes in rock pocket mouse populations, as discussed in the short film The Making of the Fittest: Natural Selection and Adaptation.

This activity allows students to collect and analyze data on the evolution of coat color in rock pocket mouse populations living on differently colored substrates.
