Duration 00:27:59
Scientists, soldiers, and landowners collaborate to save the endangered red-cockaded woodpecker at a North Carolina army base.
This activity explores an image of a wildlife overpass crossing a major highway, which serves as a phenomenon for learning about habitat fragmentation and conservation.
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 activity, students analyze scientific figures to understand principles of island biogeography theory that determine the number of species in an isolated habitat.
This activity explores the concepts and research presented in the short film From Ants to Grizzlies: A General Rule for Saving Biodiversity, which explores the species-area relationship and its applications for conservation.
