Sal Kahn has built a tremendous collection of over 1800 open-licensed videos offering instruction in math and science. They cover topics in arithmetic, algebra, geometry, statistics calculus, and more. These videos are licensed under CC BY SA which means you can use them free of charge and even host them on your own web site, as long as you agree to share (use a CC BY SA license) on any derivative products you build.

Up until now, the videos have only been available on YouTube, which has posed problems for educators. Now, however, the Khan videos are available elsewhere! Curriki has them available as both embeddable and downloadable files. They have also created a group to “organize, extended and build a community of practice around this content.” This is a great opportunity to collaboratively remix this content and add to it. (I have some ideas myself to to remix some of this into a series of middle school math courses in Moodle.)

Another site has collected the Khan videos for download onto a USB drive or server.

There are sure to be more creative uses of this great collection of content to come.

The challenge is to make an audio or video podcast answering the question “What do you think is NASA’s greatest exploration achievement in the past 50 years and why?”

The competition starts on Oct. 1 and ends after they’ve received 1,000 entries in each category (or on Jan. 4, 2008 if that comes first). This is open to U.S. students age 11-18.

See all the details on the 2nd Annual 21st Century Explorer Podcast Competition web site.

Quirks and Quarks – a science-related radio show produced by CBC Radio One in Canada

NOVA podcasts – several different podcasts from NOVA, the highest rated science series on television

Science Friday – the popular NPR science show

The Science Show – a Radio National show from Australia

NPL Celebrating Science Lectures – video podcasts of lectures from NPL, the UK’s National Physical Laboratory (a little higher level than the others)

Here is a site that has a directory of many museums that are podcasting. These include science museums. What a great way to supplement your virtual (or real) field trips.

For advanced high school students, there are also a number of universities that podcast their lectures, such as Berkeley.

Of course, as with all podcasts and other web materials, make sure to screen individual episodes for studen appropriateness.
