In regards to education, this can be a valid exercise, but needs to be implemented correctly. In my experience, if you (or your mentors, or ...) lecture at the students for more than a meeting or so, the students will start to wonder why they've signed up for another class. Some may like this, but there's a good chance many won't. Try the one-on-one (or up to about one-on-three) approach instead.Specific ideas: Try having the some kids work on CAD (if you know it) as all this requires is access to a computer lab and they can create as many designs as they want. Having some sort of hands-on activity is critical, though, as many students (esp. freshmen) will not have the patience for CAD. VEX has also been mentioned, which is excellent if your team has $700-$1000 to spend on it (I believe this is about the price range actually needed). Also, try asking veteran teams in your area if they have any extra parts and material you could use if you can't afford your own (no matter what type of robot you build). Try to stay away from some of the more crafty hobby kits that are available or more DIY-type projects, as they usually require a fair amount of precision to get working and if you have a whole room of kids competing for your assistance, neither they nor you will be happy.
