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.

Lizards in Hurricanes

This activity explores images of anole lizards subjected to strong winds, which serve as phenomena for learning about natural selection and the impacts of extreme climate events.

Lizards in the Cold

This activity guides the analysis of a published scientific figure from a study that investigated how anole lizards may adapt to extremely cold temperatures.

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.

Cancer Cell Invasion

This activity explores an image of tumor cells invading muscle tissue, which serves as a phenomenon for learning about cancer, mutations, and cell division.

Role of p53 in the Cell Cycle

This activity analyzes a published scientific figure from a study that investigated the role of p53 in cell cycle regulation.

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.

Viral DNA Integration

In this hands-on activity, students model how a double-stranded DNA copy of the HIV genome is integrated into the host cell DNA.

HIV Protease Inhibitors

This demonstration models how the HIV protease enzyme functions and how its activity is blocked by a class of anti-HIV drugs.
