NC State Libraries has created several videos on information literacy "big ideas" - general concepts that are important for students to know, rather than specific tools or search strategies. They have intentionally made them non-institution specific (except for their own logo at the very end). Many are quite short, and they could easily be used during an instruction session to demonstrate a concept. They are creative commons licensed, so they could also be included in libguides, etc. Check them out when you get a chance!
