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.
In this Click & Learn, students explore factors that contribute to patterns seen in the Keeling Curve: a continuous record of atmospheric CO2 starting in 1958.
This film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years.
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.
This activity explores an image of tattoo ink particles inside cells, which serves as a phenomenon for learning about the structure and color of human skin.
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 animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.
This activity guides the analysis of a published scientific figure from a study on how social status affects the expression of genes involved in immune system processes.
This activity analyzes a published scientific figure from a study assessing if the microbiota from a mother affects the immune systems of the developing offspring.
