I found an awesome podcast source located at: Http://www.sciencefriday.com/kids/sfkc20050415-2.html

What I particularly liked about the Website was a complete introduction and summary of the varies Podcasts available, sources, and application in the classroom. This is a Site that is devoted to Science and has continual updates.

This particular podcast is about President Bush's determination to establish a working base on the moon as a jumping off point for further space exploration and a possible manned trip to Mars. Now NASA scientists think they may have found just the spot for such a base – the moon’s north pole. The sun never sets at the pole, so the temperature is a fairly constant -50 degrees centigrade (like a cold day during a Minnisota Winter)and the constant sunlight could be an endless source of energy. Also, Scientists believe that crates that are continually in sunlight have been discovered. Some scientists believe that there is water-based ice at the top of the moon which could be melted for human use.

As the posts are updated minimally on a weekly basis, I could see how a science instructor could use this Podcast as an extension to their daily curriculum.
