This activity explores images of tree growth in the Serengeti over time, which serve as a phenomenon for learning about and modeling species interactions in ecosystems.
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.

Scientists, soldiers, and landowners collaborate to save the endangered red-cockaded woodpecker at a North Carolina army base.
This activity explores an image of a wildlife overpass crossing a major highway, which serves as a phenomenon for learning about habitat fragmentation and conservation.
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.
In this inquiry-based activity, students engage in science practices to figure out why some people with a genetic condition that usually leads to sickle cell disease do not have disease symptoms.
This video presents an intriguing phenomenon: two patients who carry the same genetic variation, which is known to cause sickle cell disease, have very different outcomes.
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.
In this activity, students analyze scientific figures to understand principles of island biogeography theory that determine the number of species in an isolated habitat.
