This activity guides the analysis of a published scientific figure from a study on how social status affects the expression of genes involved in immune system processes.

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.

Stalking the Genetic Basis of a Trait

This activity supports the film Popped Secret: The Mysterious Origin of Corn. Students analyze data on the expression of the tb1 gene to explain how variations in this gene played a role in the evolution of corn.

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.
