Music, technology and learning all in one!

So, I was trying to think of something that I could put on here that would demonstrate how both music and technology could be integrated into an elementary class's curriculum. I tried finding video of an actual classroom using music in their math or science lessons but couldn't find anything I liked. Then I remembered something that I used when I was in school and maybe others of you have as well. School House Rock. Yeah, I loved it and I'm pretty sure it's one of the only reasons that I still know my parts of speech today. =-) So, I found a few of my favorites for yours and my viewing pleasure and reminiscence. Enjoy.
