I believe one of my first lessons will be to teach my students about digital footprint longevity by showing them the youtube video photofate.  Next I will have my students respond to the video in a think share pair, followed by a class discussion.  I may show them additional videos regarding unexpected consequences of digital posts and have students create a small group sketch note, meograph, pixton or spreakerDJ.  Each group will present their presentation to the class.  The class will vote on the best presentation which will be uploaded to the school cloud and shown to the entire campus during lunch.  In this way, students get to create original presentations showcasing the potential consequences of inappropriate digital faux pas that their peers may view.
