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.



Meet Sasha. At age 8, she's a real social butterfly, both online and off, and is very concerned with how the world sees her: she spends a lot of time making sure she looks good in photos online but doesn't always think twice about who might see them. Violet is Sasha's older sister and her polar opposite: she's a hardcore gamer, and just as tough as her Level 65 Barbarian. Though she despairs of her sister sometimes, she's also fiercely protective of her and will unleash her considerable wrath on anyone she thinks is picking on Sasha.
