This video describes how indigenous communities from the tropical rainforest of Darién, Panama, use drones to map their lands. The communities use these maps to protect their territories from outside incursions and to design sustainable land-use plans.

This activity guides the analysis of a published scientific figure from a study that investigated how random mutations during cell division can contribute to cancer.

This activity guides the analysis of a published scientific figure from a study on low-oxygen areas in the ocean called dead zones.

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

This interactive module allows students to explore the science of Earth's deep history, from its formation 4.5 billion years ago to modern times.

This activity allows students to calculate the mass, size, and kinetic energy of an asteroid that struck Earth 66 million years ago, based on the total abundance of iridium in a sediment layer. It supports concepts presented in the short film The Day the Mesozoic Died.

This activity allows students to analyze the chemical data that led researchers to conclude that a layer of clay at the boundary between the Cretaceous and Paleogene rock layers (the K-Pg boundary) contained an extraordinary concentration of iridium. It supports concepts presented in the short film The Day the Mesozoic Died.
