It's more just to get them in the door, see who and what and where we are than for learning much. I try to get teachers to allow them some general browsing time while they're here. Library orientations for incoming freshman before their first assignment. When they complete each task we stamp the passport. Then, it is followed up with an assignment collaborated on by me and the teacher.
Teachers are impressed that kids can get right down to work.
I feel this method is pretty meaningful for the students. Along with this, we have the students do a library mosaic research project. They then go to several specified resources from which to draw a quote. Once they have acquired a quote from each specified source, they write them in various spaces on a mosaic template, a piece of paper on which spaces have been lined out in a puzzle design. The students are to include pictures, drawings, color, etc., to fit their topic and make their final presentation attractive while presenting information about their topic.
