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 Click & Learn traces the flow of energy from the Sun all the way to cells within organisms. The embedded questions and calculations guide students’ understanding of how energy is distributed through a variety of ecosystems.
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 activity explores images of a coral bleaching event, which serve as phenomena for learning about marine ecosystems, human impacts, and climate change.
The added information provided at pause points within the animation Coral Bleaching allows for a richer exploration of coral reefs, symbiosis, and other topics in biology.
This activity explores an image of a wildebeest herd on the Serengeti, which serves as a phenomenon for learning about population dynamics and wildlife management.
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 guides the analysis of a published scientific figure from a study that investigated how herbivore populations are regulated in the Serengeti.
This activity explores an image of termite mounds in the African savanna, which serves as a phenomenon for learning about ecosystems, competition, and feedback loops.
