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 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 activity guides the analysis of a published scientific figure from a study that compared the testosterone levels of Olympic-level elite athletes.

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 planarians regenerating missing body parts, which serve as phenomena for learning about cell division and differentiation.

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 guides the analysis of a published scientific figure from a study that investigated the effects of tourism on cougars and cottonwood trees in a national park.

This activity allows students to formulate and analyze scientific questions.

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.
