history and geography lessons would benefit from images available through the free Google Earth program, with which you can take students virtually to any location, such as the Grand Canyon or Eiffel Tower. For other subjects, sites such as Google Video and YouTube have coverage of recent and past news, political speeches, and social commentary, so these video sites can be great economics, history or current events tools. Most videos on these sites range from one to ten minutes long and can easily provide enrichment on a subject within a brief window of classroom time.
