You've heard of Flickr, and you've heard of Google Earth, but have you heard of
http://www.taggalaxy.com ? Taggalaxy is a mash up of Flickr and Google Earth. Simply enter a "tag" or topic into the text box and watch as your topic is broken down into subtopics. For example, if you entered the tag
castles, subtopics like French castles, English castles, etc. will appear on satellites floating around your original tag. Click on any of the satellites and any Flickr photo thumbnails that match your tag will automatically appear on your satellite. Click on any photo to enlarge it. Note that since Flickr photos are constantly being updated, it's important to save any photos you might like to use in class to a PowerPoint, slide show, or voice thread. Use the photos for journal prompts, time lines, story starters-great possibilities.
