Integrating Language Arts/Social Studies through Podcasting

I really enjoyed the podcast we heard from students on Famous Americans a couple of weeks ago. It made me think of how we could use podcasts to present our Famous Americans in 3rd grade. I think that using podcasts to present conversations or reports on Famous Americans would be great for using after the SOL tests. After the SOL tests we are always looking for fun and engaging activities to have the students complete. Using the Famous American podcast will incorporate Language Arts writing with the conversation/report, and the information of the Famous Americans falls under Social Studies. Does anyone have other ideas on how to integrate curriculum through podcasts?
