The United States Geological Survey (USGS) has brought together a unique blend of materials designed to complement and enhance the experiences of teachers and students seeking to understand the wide world of geology and other sciences, including geography, ecology, hydrology, atmospheric sciences, and planetary sciences (2021).

The online encyclopedia includes essays and other educational material on historical subjects (including British history and the history of the United States as well as World War I, World War II, Russian Revolution, slavery, women's suffrage, Nazi Germany, Spanish Civil War and Cold War). (U.K. 2005-2021)

The primary sections of the site include ʺStudent Activitiesʺ, ʺTeacher Resourcesʺ, and ʺPublicationsʺ (2008-20).

This teaching resource uses New York Times articles and Op-Eds to investigate the issue (2019).
