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 interactive module can be used to model infectious disease spread in a population. It includes background on the SIR model and two simulators for modeling disease spread on different scales.
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.
