Lesson
Taking Back What You Can
Summary
Deleting a post doesn't actually delete it—screenshots, backups, and app permissions keep your data alive long after you hit that button. This lesson unpacks how app permissions work, why some access is necessary and some is exploitative, and how students can audit and lock down their own devices.
Bellringer: The Illusion of Deletion
- Display the deleted-photo scenario and have students list two places it could still exist
- Cold-call a few answers before moving to discussion
Instruction
- Walk through how deletion doesn't erase data (backups, archives, screenshots)
- Teach app permission categories and the "necessary vs. extra" test
- Cover spy permissions (location, mic, camera) and how to check/turn off settings
Discussion: Whose Job Is Privacy?
- Pose the responsibility question—tech companies vs. users
- Have students share what they know about lawsuits or news on teen data exploitation
- Brainstorm laws or restrictions that would help protect teens
Activity: Digital Footprint Vocab & Posttest
- Students complete Digital Footprint Vocab review
- Students take the Digital Footprint Posttest to close out the unit
Wrap-Up & Assessment
- List 3 privacy settings on your smartphone or favorite app.
- Which precaution are you most interested in taking to protect your data? Why?
