Today’s students face a digital world full of clever tricks designed to influence what they think, believe, and share. This paper explores how bad actors use social engineering—like impersonating trusted sources—and disinformation—such as fake news headlines—to manipulate their audience. We’ll also examine disinformation folklore: the viral memes, rumors, and stories that feel like modern myths and are especially convincing to young people. Through real-world examples and practical tools, school librarians will learn how to help students identify these tactics, think critically about what they encounter online, and respond thoughtfully. By equipping students with these skills, librarians play a vital role in creating informed, resilient digital citizens
