Getting the Toothpaste Back into the Tube: A Lesson on Online Information
In this lesson, students watch a short video that compares getting rid of personal information online to getting toothpaste back into a tube. After a short discussion of how visual analogies like this work, students discuss the meaning of the video (that information online is permanent.) They then read a series of short scenarios that help them identify four further principles of information online: that it can be copied, that it can be seen by unintended audiences, that it can be seen by larger audiences than intended, and that it becomes searchable. Finally, students create a simple animation that illustrates one of these principles.
