Teaching 4th & 5th Grades to find & evaluate information using the internet

I am the technology teacher at a small private school. I am studying for my M Ed in Learning Technology and have built an instructional unit to teach fourth and fifth graders how to find and evaluate the information they need using the internet. I need to find a Subject Matter Expert to review my unit as part of the formative evaluation I am conducting. Is there anyone out there who would be willing to read through the materials and answer some questionss?
