I looked at a lot of drawing tools since I have to make a lot of diagrams for physics. I found one called Sketchfu that is fun because it makes a movie out of the drawing showing it as it progresses. I made a sample which I have included here. I could use this for demonstrating problems and I could include the progression of the equations as the problem is worked out. This was fun to do and I will probably use it in class.
I have used itunes on my ipod for a while now so it was not a problem. The itunes store had a lot of podcasts that I would like to listen to. I subscribed to some NPR podcasts and to one from the Onion. I could see using podcasts in class when there is a science in the news event. I probably would not use ipadio or my own podcasts because it would be easier to make instructions or hints using other webtools because I could include images. I made a short podcast about my vacation in England.
