Paige, I shared this with my district the other day. I'm posting here thinking you might could use this resource.
Google and iKeepSafe have teamed up and developed a curriculum to assist educators with modeling to students how to be a responsible online citizen. This site has extensive resources on internet safety for teachers to use with students. The information is upbeat, and, most importantly, current. What you will find here teaches students how to safely use all types of social media and YouTube, how to be a good digital citizen, and how to evaluate a website. There are three “workshops” with videos, lesson plans, handouts for students, and a slide show presentation to accompany the lesson. Everything is put together for you, so take a look! An added bonus to looking at this site, is that on the left you will find links to other google sites for educators.
The Google resource Deborah shared I too use quite often- which is excellent. Thanks Deborah :-)

If you are looking for videos confronting students and how they dealt with them, a good site to consider is NetSmartz http://www.netsmartz.org. It has information for parents, educators, law enformcement, etc and provides a number of issues that you may select from. You should also consider brainpop www.brainpop.com and then do a search for digital literacy. If you are looking for literature to supplement your talk, "The New Writing Pedagogy" in the District Administration is a good read http://www.districtadministration.com/viewarticle.aspx?articleid=2202.
