teaching federated searching

Now that summer is here and I’m not teaching any classes, I have to think about what I’m going to be teaching in the fall. We’re getting a federated searching tool, and I’m trying to figure out how to integreate it into all of the basic freshmen classes that I teach. I mean in a 50 minute class things might break down like this:

-class starts 5 min late, so you really have 45 minutes.
– (5 min), introduce self, show where to go to get help with research, orient class to library web page, pointing out the more useful bits.
-search concepts, why you have to search differently in library databases as opposed to google (the joy of boolean), how library databases differ from google (5-10 min)
-introduction of federated searching tool (less than 5 min)
-fun with a particular article database (5-10 min)
-how to track down journals using the library catalog (2 min)
-more fun with the library catalog (2 min)

If I add up all that allocated time I’m using up 40 minutes, which is way too much. I prefer to spend much less time talking to students and give them more time to actually run their own searches while I can go around the room and help them out individually if they run into any problems.

I’m inclined not to spend a whole lot of time on the federated search tool, because I think a quick demo will show students how nifty it is, they’ll probably use it all too much anyway, and I’d rather show them search techniques in an individual article database (since some of them might not have used them all that much to begin with), pointing out that the federated search tool could give them an idea of what other article database would be useful, or give them a quick overview of the sources available.

I don’t know though, does anyone have any tips?
