I-Tunes U & PBS

I chose to watch the Observe Clouds in the grades k-5 section. The video consist of watching clouds and at one point they sped up the tape. There wasn't much to the video I watched, however they also include and Educator's Guide. The guide provided a summary, discussion questions, background information, and helpful links. The best thing about this is that it is free.
I believe this will become a great resource in the classroom. I can hook it up and play a video for the whole class, or set it up as a center at a computer. I hope to give every child computer time, so I can easily set this up as an assignment, providing them with questions to answer.
There is another channel in Itunes U that I found to be very interesting. It is called Little Kids Rock. It is a nonprofit group that restores music education to public schools, and they do this free of charge. They have posted guitar lessons and drum lessons. They also have videos of kids playing that learned to play from their videos.
