How to safely live in a digital world:
The padlock is to remind students to set strong passwords and to set up passcode locks on all of their digital devices. “Lock ‘em down” as we like to say in our Digital Citizenship lessons.
I tell students to think that passwords and toothbrushes are very similar in the fact that you NEVER want to share passwords. (I do highly encourage/recommend that students to share passwords with parents)
Everything that you put online is permanent….even if you hit the delete button after posting. Odds are someone has retweeted, favorited, or taken a screenshot of the material if it was questionable.
Imagine the information that you are putting online is like the toothpaste coming out of the tube. Once it is out, it is almost impossible to get it all back in the tube! (Thanks to @Mandery for that prop idea!)
