Do Students Frown on Information Literacy?

I'd like to follow up on my last entry.  After 4+ weeks students finally submitted their assignments in the class on how to find physical and thermodynamic properties of substances.  What is their reaction to an outsider coming into their class to give a lecture?  Would their attitude be different if their professor gave the information literacy lecture.  I find that students do well on the assignment even after procrastinating.  Perhaps I have made the assignment too easy.  I do think that students should gain experience in using free and subscription databases to find information.  However, it is inevitable that they will just Google to find the information they need.  Are they interested in learning new skills or just to get their grade and finish it?
