Wikipedia's site for kids can be found at Wikiforkids.ws. The website removes content that is not appropriate for younger readers and uses simple language and grammar to make reading the articles easier for children.
Wiki for Kids uses Google SafeSearch Tools to search Wikipedia and also uses enhanced filtering to provide even more online safety in the search results. These services are provided by Safe Search Kids as part of Google's Custom Search Engine program, although Safe Search Kids is not actually a part of Google. Along with safe text results, the Wiki for Kids also provides a way to search for images that have been filtered and are deemed appropriate for children.
