A new challenge is trending on social media. It involves doing a prank that could get people in trouble. Most of your classmates are talking about it, and a few have already done it. They’re pressuring you to join in and post your own video.

The class has a substitute teacher. As soon as the teacher turns to write on the board, a few students start throwing paper balls. Others join in, laughing. You haven’t done anything yet, but your friends are encouraging you to “just do one.”

A new student sits at your lunch table. Some kids start whispering and making fun of their clothes. Most of the table joins in or stays silent. You feel uncomfortable but don’t want to be the only one to speak up.

During a surprise quiz, a student near you whispers the answers to their friend. A few others start doing the same. The teacher doesn’t notice. Everyone seems to be getting away with it. You studied but aren’t sure about some answers.
