The following site looks like a great search engine for young kids:
AllSafeSites is a kid-friendly directory & search engine for fun, educational and most importantly, SAFE websites.
Each site in our directory has been personally reviewed and recommended by an elementary school teacher. There are many similar web sites for kids, but a couple of things set up apart.
First of all, we have no advertisements on our page. The primary reason is that most advertisement programs are deceptive in nature and attempt to lure the user away to another web site that is often not suitable for children.
Another differentiator is that AllSafeSites is designed with visual aids so that very small children, even those unable to read, can navigate the web site easily. Most other sites are primarily text-based, making them difficult for young children to use.
