Windows to the Universe is a user-friendly learning system pertaining to the Earth and Space sciences. The objective of this project is to develop an innovative and engaging web site that spans the Earth and Space sciences and includes a rich array of documents, including images, movies, animations, and data sets that explore the Earth and Space sciences and the historical and cultural ties between science, exploration, and the human experience. Some of the main resource areas of the site are Our Planet, Our Solar System, The Universe, Myths, Art, Books and Films, Space Missions, People, Headline Universe, Cool Stuff, Data, Geology, Life, and Ask a Scientist. Each topic links to numerous facts, figures, and related sites. There are beginner, intermediate, and advanced options for each topic level. Multiple search engines allow the user to browse by keyword, by educational standards, and the Ask a Scientist archives. Special sections are reserved for kids, with games and fun activities, and teacher’s resources, such as a workbook and lesson plans. Updates to Windows to the Universe occur on a regular basis, so resource users are invited to revisit the site regularly to see the resources grow and change.
