Science Teaching Tips

The final episode of Science Teaching Tips has been posted. But don't despair! They've been given new life (and a new webhome) over at http://exploratorium.edu/ti/podcasts. Check out the new location, it's all spiffy and snazzy, and listen to all the great episodes of the compiled wisdom of the Exploratorium's Teacher Institute. Enjoy!

There is only one episode of Science Teaching Tips remaining! There is no more funding to continue producing this podcast. If you're interested in seeing this continue, please let me know (and perhaps I can scrape together some funding). If you have a suggestion of where we might find some dollars to keep producing this, please, do tell! It's been a lot of fun and we have a lot of subscribers, I'd love to keep doing this.
