Evolution of Ant-Mimicking Beetles

This activity guides the analysis of a published scientific figure from a study that explored the evolutionary origins of parasitic beetles that mimic army ants.

Mozambique Mounds

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.

Mate Choice in Spiders

This activity guides the analysis of a published scientific figure from a study that investigated how males in a species of sexually cannibalistic spiders choose their mates.

Monkey Social Status and Immune Response

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.

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.

Benefits of Schools

This activity explores images of animals that live in groups, which serve as phenomena for learning about animal behavior.

Mimicry in a Diverse Community of Arthropods

This activity guides the analysis of a published scientific figure from a study that tested how effectively mimicry protects arthropods against different types of predators.

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.

Bat Echolocation

This activity guides the analysis of a published scientific figure from a study that tested how bats use echolocation to adjust their hunting behavior.

Selective Breeding in Maize

This activity guides the analysis of a published scientific figure from the world’s longest-running controlled artificial selection study, in which scientists tested whether they could use selective breeding to change the protein concentration of maize (corn).
