I am trying out a Livescribe pen to illustrate the solutions to the refraction homework students worked on over the weekend. Since we are having a quiz tommorrow I thought I would not only share the solutions in class but would also share them as a pencast.
Try these links for the solutions.
- As a Livescribe pencast (this includes audio)
- As a PDF (you will only hear the audio if you are using Acrobat 10 or later)
