Spezify

Spezify is a visual search engine.  You can type in a word or phrase that you want to search, similar to what you would do in Google, and it will come up with results in picture or "news clipping" looking format.  I know students would really like to do this, and it also would be a useful tool for those beginning readers to search for pictures of words.  This site, just like Google, doesn't necessarily have a "student friendly" filter, but I've found that if you search for something a little more specific, like "fractions math" and not just "fractions," you will come up with a more educationally focused result. 

Here's a screen shot from my search for "Trumpeter Swans."  You can see the "play" buttons on some of the images because they are actual videos from YouTube.
