Just received this from Crocodile Clips people. Some useful stuff here. Note of caution, check accuracy before use.
Today, we've launched a new collection of free online whiteboard resources. They are from our Absorb courseware, and offer a wide range of simulations, animations and models across secondary school science and mathematics.
You'll find these resources at
http://www.yenka.com/freecontent/
You can use them in schools and at home, and there's no need to register - just search or browse for the content you want.
We hope you find them useful. I'd very much appreciate hearing any comments you have, or any suggestions for the future - you can e.mail me, or leave a comment on the blog on the website. Valentin Juhasz newsletter@crocodile-clips.com
