As part of the Oklahoma Climatological Survey, the Educational Outreach Web site contains a References page for teachers. The materials provided are "intended to be used by teachers as refresher information prior to teaching a given subject... and are not meant to be comprehensive, but should provide adequate depth in the subject for use by most K-12 teachers." Titles of the materials include Atmospheric Water Vapor and its Importance, Common Meteorological Variables, The Seasons, Earth's Energy Budget, Cloud Development, Precipitation, High and Low Pressure Systems, and several others related to weather and climate. Other sections of the site include lessons, references, a glossary, and other helpful educational materials for teachers and students.
