Open Education Resources: NASA Earth Observatory:
This website is an old favorite for use in adult basic education. Through satellite images, one can learn a lot about Earth science/space science, geography, technology, the uses of mathematics, and current events (meteor fragments over the Urals, for example). Here is a brief sample of the riches of this resource:
Image of the Day: http://earthobservatory.nasa.gov/IOTD/
The image for February 27th shows ocean sediment swirling around Cape Cod, Massachusetts as a result of “the erosive power of a recent New England storm”. You can sign up to receive a daily satellite image, complete with connections to science and its practical applications.
