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.
This video follows germplasm bank coordinator Cristian Zavala Espinosa and geneticist Sarah Hearne, who are part of the global effort to preserve the genetic diversity of maize (corn).
This interactive tool introduces students to building scientific models. Educators can use the tool to create assignments and, in some cases, automatically grade student models.
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.
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.
