In this activity, wildfires and how much area they burn serve as a phenomenon to guide student inquiry, which includes evaluating data and developing scientific claims.

This activity explores images of a coral bleaching event, which serve as phenomena for learning about marine ecosystems, human impacts, and climate change.

This activity explores the concepts and research presented in the short film Out of the Ashes: Dawn of the Age of Mammals, which explores how life on Earth recovered after a major asteroid impact.

This activity explores images of stickleback fish, some with spines and some without spines, which serve as phenomena for learning about gene regulation and natural selection.

This activity explores an image of fossil footprints at Laetoli, which serves as a phenomenon for learning about fossil evidence and human evolution.

This activity guides the analysis of a published scientific figure from a study that investigated how salt affects the electron transport chain.

This activity guides the analysis of a published scientific figure from a study that used footprints formed millions of years ago to estimate the heights of early human ancestors.

This activity guides the analysis of a published scientific figure from a study on prehistoric human food sources. In this study, scientists used carbon isotopes to determine how the advent of agriculture affected human diets.
