Modeling the Structure of DNA

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.

Patterns of Predation

This activity guides the analysis of a published scientific figure from a study that investigated how herbivore populations are regulated in the Serengeti.

White-Nose Syndrome

This activity explores images of bats with an infectious fungal disease, which serve as phenomena for learning about population dynamics and disease impacts.

White-Nose Syndrome in Bat Populations

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.

The Wolves of Isle Royale

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

Serengeti Wildebeest Population Regulation

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.

Modeling Food Webs in Darién, Panama

In this activity, students use cards to build model food webs and evaluate how ecological disturbances affect each trophic level using information from the citizen science website WildCam Darién.

Predator-Prey Relationship Dynamics

This activity guides the analysis of a published scientific figure from a study about Arctic fox populations and their main prey, lemmings.

Modeling Trophic Cascades

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.

Viral Lysis and Budding

This activity outlines two demonstrations that model how enveloped and nonenveloped viruses are released from infected cells.

HIV Receptors and Co-receptors

This demonstration models the first step of the HIV life cycle: the binding of HIV envelope proteins to receptors on human helper T cells.
