In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment.
Explore the microscopic world in this Educator Voices article from Pennsylvania educator Bob Cooper, who zooms in on the world of the very small with the “What Leeuwenhoek Saw” activity.
This activity guides the analysis of a published scientific figure from a study that investigated physiological and genetic adaptations in the Bajau, a group of people who traditionally do freediving.
This film explores the species-area relationship, a general ecological rule that describes how the number of species in a habitat changes with area, and shows how it has been applied to the conservation of protected areas.
This activity guides the analysis of a published scientific figure from a study that investigated genetic factors contributing to skin color differences, particularly within African populations.
This activity explores images of animals with a mutation that affects coloration, which serve as phenomena for learning about skin color genetics and evolution.
This activity explores images of bats with an infectious fungal disease, which serve as phenomena for learning about population dynamics and disease impacts.
This activity guides the analysis of a published scientific figure from a study that modeled the impact of an infectious fungal disease on a bat population.
This activity builds on information presented in the video Selection for Tuskless Elephants. Students use scientific evidence and reasoning to construct an explanation of and develop an argument for tusklessness in elephant populations.
Thanks to the compounds used to protect precious flowers, antifungal resistance is here—and it could be just as dangerous to humans as antibiotic resistance.
