In this activity, students build a paper model of DNA and use their model to explore key structural features of the DNA double helix. This activity can be used to complement the short film The Double Helix.
This activity guides the analysis of a published scientific figure from a study that investigated how herbivore populations are regulated in the Serengeti.
This film explores the foundational research in the Serengeti National Park, Tanzania, that uncovered many of the ecological principles that govern how animal populations and communities are regulated.
This activity explores an image of termite mounds in the African savanna, which serves as a phenomenon for learning about ecosystems, competition, and feedback loops.
This animation shows how mutations in an ion channel protein lead to the genetic disease cystic fibrosis. The animation also discusses how research on this protein has been used to develop treatments for the disease.
In this activity, students model trophic cascades, which are also explored in a variety of related resources, using cards of animal and plant species from seven different habitats.
In this video, ecologist Brian Silliman explains how he uses manipulative field experiments to study salt marsh ecosystems. His approach revealed that these systems are under top-down control from consumers and predators.
This video follows ecologist Mary Power, who is studying the Eel River in Northern California to decipher the connection between river flows and biodiversity.
In this talk, scientists Beth McGee, Mary Power, and Brian Silliman discuss the Chesapeake Bay, its food web, and the challenges of conserving and restoring the Bay.
This activity guides the analysis of a published scientific figure from a study that investigated whether periwinkle snails contribute to salt marsh die-offs.
