I really like this to, once your register you can log in to the media files, I really like this as well. We are working with the middle school age curricula.
Another good science resource site that I found that caters for science students K-8 is www.experiland.com
Thanks for sharing!
This is another one, beestar. It is curriculum-based from 1st grade to 8th grade. The program is full of all real life word problems, challenging stuff to help kids thinking - some of them make my daughter think or is a great opportunity for me teach advanced concepts. I think it is well and easy-used program.
