A message can change everyone’s plans. Start with the missing sentence.
THE BLOCK , CASE 1
The clip cuts off right there
Malik opens a group-chat message about Friday's school dance.

Which claim can the screenshot establish by itself, and which claim requires finding the original post?
Use it in a case
Use a fictional school-closing rumor in a group-chat frame. Students separate visual clues from actual corroboration, then write a correction that does not amplify the rumor.
