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 highly customizable activity guides students through organizing and documenting spreadsheet data during a class investigation.

This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).

This video follows biologist Elinor Karlsson, who studies dogs to find genes associated with traits, including certain diseases.

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 web tool provides a quick and easy way of visualizing and analyzing data without advanced technological requirements.

In this activity, students work with authentic research data to explore the impact of poaching on African elephants.

This activity explores images of elephants with and without tusks, which serve as phenomena for learning about selection and human impacts on the frequency of traits within populations.

This film explores how life recovered after an asteroid wiped out the dinosaurs and how those events shaped the diversity of plants and mammals on Earth today.

This activity explores an image of a moth with unusual markings on its wings, which serves as a phenomenon for learning about mimicry and adaptation.

This video case study explores whether elephants can detect, interpret, and respond to signals delivered by underground vibrations.

This activity guides the analysis of a published scientific figure from a study that explored the evolutionary origins of parasitic beetles that mimic army ants.
