Io videos (i.e., Io videos):

1. Io's Volcanism | 0:20 : A collage animation from Kurdistan, but based on NASA images which are mostly public domain. It shows Ioian volcanic eruptions. Short enough for the classroom.
2. Io moon from Jupiter HD (NASA) | 2:03 : OK as a music video: Edvard Grieg (1843--1907): Peer Gynt (1875): Morgenstimmung. Could show a bit, but too long for the classroom.
