The resources described here were created by Deutsche World, the German equivalent of BBC World Service. They consist of 12 short video snippets to support science teaching.

With a cartoon Einstein to guide students through the principles, they are simple to use and understand. You can see all 12 videos here

They're worth mentioning for two reasons:

1. You might have a science teacher colleague who'd value the link (E=mc2 in under 2 minutes? When is your thumb bigger than a house in 1 min 43 seconds?)
2. They make use of Microsofts new Silverlight system and are beautiful to look at!

Enjoy!
