Alec Couras found this site. He writes a wonderful blog that you should be checking out. His was one of the first blogs I subscribed to and I always find something worthwhile when I visit. This is no exception. It’s from the University of Nottingham. They’ve developed a Periodic Table of Videos about the periodic table of elements. Elementary, some would say!!
This is great. There’s nothing more dry than trying to memorise those elements. At least using these your students will have a visual element to peg their learning to (excuse the pun!). They’re not trying to be radical with these videos, but they will be useful I’m sure for Science teachers everywhere. A great initiative from the University of Nottingham.
And don’t forget, if you have problems loading the vids from their YouTube channel , under Australian copyright guidelines you can convert the file to another format that you can download to your computer so that the video will play straight away in class. I use Keepvid and download to Mpeg 4 quality for playback. Easy done and saves loading problems.

I passed this on to my science teachers. The phosphorus video was interesting. I really enjoy Alec’s blog, as well. I’m glad I saw your mention of this on Twitter.
