This is a neat new site billing itself as the Information Experience! I've been following Qwiki for several weeks now during there Beta phase and I have enjoyed their daily emails with links to the Qwiki of the day.
Try is out. Click on the title to go to the site. Then all you have to do is fill in your topic in the search box and wait for the Qwiki to load. The computer then reads the information while you look at the text and pictures. Additional related Qwikis are included at the bottom and once the Qwiki is over you see more related Qwikis and links to other sites on your topic.
I love Qwiki and recently added a number of links on our classroom social studies page. I've embedded a qwiki on the Whitehouse below. Enjoy!
