Did you know that wikipedia have produced content especially for schools in the UK? No, neither did I until I was pointed towards it today by @dannynic
Wikipedias own explanation;
"This 2008/9 Wikipedia DVD Selection is a free, hand-checked, non-commercial selection from Wikipedia, targeted around the UK National Curriculum and useful for much of the English speaking world. It has about 5500 articles (as much as can be fitted on a DVD with good size images) and is about the size of a twenty volume encyclopaedia (34,000 images and 20 million words).
Wikipedia is the free encyclopaedia anyone can edit, and develops accurate content but suffers vandalism. Wikipedia is not necessarily a childsafe environment and has "adult" content. This selection of topics have been carefully chosen, tidied up, and checked for vandalism and suitability (by SOS Children volunteers, whom we gratefully acknowledge). We also gratefully acknowledge the Wikimedia Foundation for their support and their agreement to our use of the Wikipedia logo, and tens of thousands of contributors to Wikipedia who have written and researched the content in the first place, including this year adding content where gaps in the school curriculum were not covered"
The entire content of the Schools Selection can also be downloaded (no need to go online at all - ideal for a non internet PC), or as a DVD from the SOS Children website.
