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.

In this activity, students engage with an example from the Serengeti ecosystem to illustrate the exchange of nutrients between plants, animals, and the environment. 

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 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 explores images of wolves hunting a moose on Isle Royale, which serve as phenomena for learning about predator-prey population dynamics.

This activity analyzes a published scientific figure from a study in Serengeti National Park, Tanzania. In this study, scientists investigated how the eradication of rinderpest disease led to a boom in the wildebeest population.

This interactive module allows students to collect and analyze data from a virtual river to construct biomass and energy pyramids.

This interactive module allows students and educators to document, annotate, and reflect upon scientific research processes.

This interactive module consists of a virtual Winogradsky column, which can be used to explore the diversity of microbes, microbial metabolic strategies, and geochemical gradients found in sediments.

This activity explores the content presented in the animated video Nature’s Cutest Symbiosis: The Bobtail Squid, which describes how the light produced by bacteria living inside bobtail squid helps the squid avoid its predators.
