This is a picture of my survival kit. The idea is to present the objects to students and have them tell you how they think each item relates to digital citizenship. The part of the activity that I enjoyed the most was that the participants came up with different and often a lot more interesting connections than were suggested on the original site.
So, how DO these items relate to digital citizenship? Here are some possibilities:
Toothbrush - Do you share your toothbrush? Most students will respond NO. So, treat your passwords like your toothbrush; don't share them.
Permanent Marker - What you put on the Internet is PERMANENT! Even if you delete something, there are traces of it.
Toothpaste - It's kind of like when you write nasty things about people on the Internet (cyberbullying), once they're out, it's almost impossible to put it back in.
Lock - Make sure your devices are secure. Use pass codes and passwords.
Extension Cord - Start with it plugged in and as you unplug it, remind students that it's important to unplug sometimes.
As I mentioned, I've heard some really interesting alternatives to these. For example, one group said the toothpaste relates to keeping what we say/write online clean. They also mentioned that the extension cord was about staying connected and that the lock reminds us that even if things appear secure, there are often ways to bypass the security.
I strongly suggest you try this activity with your students. I have some kits that I would be happy to lend. Just let me know. Here is a link to a kit with more items and ideas (http://goo.gl/qyLONm). Take a peek, improvise and get your students thinking and talking. You never know where your students may take you.
