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.
In this activity, students interpret several pedigrees of autosomal dominant and recessive conditions and consider the benefits and limitations of genetic testing.
In this activity, wildfires and how much area they burn serve as a phenomenon to guide student inquiry, which includes evaluating data and developing scientific claims.
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.
In this Click & Learn, students explore mathematical models that describe how populations change over time and apply these models to the invasive lionfish population in the Bahamas. They also use data from other species to learn how density-dependent factors limit population size.
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 video case study explores the approaches scientists used to identify a mutation that causes retinitis pigmentosa (RP), a progressive disease that leads to blindness.
