Scavenger hunt - After teaching the idiosyncrasies of search engines, directories, and agents, giver your students a list of questions to find.  Once they have found the answer, have students provide you with the URL (they can copy and paste it onto a word processor document), the keyword string they used to locate the answer, and a brief description of what problems they encountered, or if they had to do any extra "sleuthing" to find their response.  It'll get them thinking!
