Kids’ Home Page
This is a home page for my children. They are not quite old enough to have full net access and so are restricted to the list of sites below. If you have young kids this list may be useful to you. If you have suggestions for other sites they may like please add a comment.
Not sure how old your kids are, but Science News for Kids is also cool http://www.sciencenews.org/view/interest/id/3/topic/Science_News_For_Kids
