If you are taking your class on a library tour, use this scavenger hunt activity to spice it up. Although this hunt isn't actually attached (like the lesson says it is), you will get a good idea of how to implement a task like this. Learners familiarize themselves with various sections of the library as they use QR codes, an iPod Touch, and a worksheet to record various findings. Start scavenging groups at different places to keep from everyone crowding around one resource.
