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.

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.

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.

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.

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.

Synchronized Division

This activity explores an image of early embryonic cells, which serves as a phenomenon for learning about cell division and development.

Earth Systems Activity

This activity guides students through building a conceptual model of how carbon dioxide affects Earth’s climate.

Finding the Crater

This activity supports concepts covered in the film The Day the Mesozoic Died. Students will analyze geological evidence from ten different sites around the world to predict the location of the asteroid impact that caused the mass extinction at the end of the Cretaceous Period.

Weighing the Evidence for a Mass Extinction: On Land

This activity supports concepts covered in the short film The Day the Mesozoic Died. Students analyze graphs and data on pollen grains and fern spores to form a picture of the living landscape before and after the mass extinction that marked the end of the age of the dinosaurs.
