YouTube Saturday - Exploring Magnetism

We're slightly cheating this week with YouTube Saturday in the sense that this week's video does not come from YouTube at all, but Vimeo. The video looks at the secret lives of invisible magnetic fields, revealed as chaotic ever-changing geometries. It's a wonderful introduction to the world of magnets - ideal for Junior Cert Science.

The video was suggested by Noel Cunningham, a physics teacher who has his own blog: Thinkforyourself.ie. Noel also maintains a Google Group for science teachers who are willing to share resources, discuss teaching methods, share ideas, weblinks and more. The group, called Sharing Science, is available to anyone and you can join by emailing here. So far there are nearly 70 Irish teachers on the group (including myself) and it is a great way to network with other science teachers and share a common passion.
