"You couldn't get functioning democracy without free information." I really like the experiment he did with the take a screen shot and see the difference between each others searches. This would be an excellent activity for students to do for an assignment. You could define a search term then get each student to search and screen shot on their own PC and another PC in the house. The next day print off and gather all the images place them on the floor and work out what you can tell from the search results that were returned. This activity could be a spring board for discussion topics such as, ethical use of user information, surveillance, privacy and the rights and responsibilities of individuals and corporations. So there you go, online video leads to lesson idea, leads to increased awareness by students and real connected teaching based on data gathered by students... hmmm might rethink my senior IT unit on social and ethical issues and the Internet.
