Photo Detective
Students investigate described photos that were cropped, edited, or made with AI, and learn two fact-checker moves that work better than staring: Stop, and Find better coverage.
A photo can be real and still tell a false story. It can be cropped so you only see part of what happened, edited so something is added, removed, or changed, or made with AI so it shows something that never happened at all. Staring harder at a picture often doesn't help, and AI-made images keep getting harder to spot by looking. In this lesson, teams investigate ten photo cards (described in words, so no real photos are needed). They practice two moves fact-checkers use, in kid language: STOP (notice your feelings before you believe or share) and FIND BETTER COVERAGE (do other trusted sources show the same thing?). Then they crop a picture themselves to see how easily a story can change.

Handout C for Photo Detective
Crop It!
Show how cropping can change a story. Draw big and clear.
Draw the WHOLE scene. Put at least two things happening in it. (Idea: a birthday party where one kid dropped their cake and is sad, but everyone else is laughing at a clown.)
Now draw a CROPPED version that shows only one part.
A false caption someone could write for the cropped picture:
The true caption for the whole scene:
If you saw only the cropped picture online, how could you find better coverage?

Answer key and notes
Handout A: Photo Cards
- Card 1 · Model
- Better coverage: the Cedar Pond fishing club's page shows the uncropped photo. A grown-up is holding the fish out close to the camera while the boy stands farther back, which makes the fish look giant. The club's record list shows no new record this year. Final call: CROPPED (and a trick angle). Real fish, false "record" story.
- Card 2
- Better coverage: the town newsletter shows the full photo. The trash is in a pile next to a sign that says "Clean-Up Day: Bags go here!" Volunteers had just collected it. Final call: CROPPED. The picture is real; the story is false.
- Card 3
- Better coverage: the school's newsletter, two families' posts, and the weather page for that day all mention the storm and the rainbow. Final call: REAL, with an honest caption.
- Card 4
- Better coverage: no space agency or news source reports a cat in space. The person who posted it says in the comments that they made it with an AI image tool. Final call: AI-MADE. Fun, but not real, and the caption makes it sound true.
- Card 5
- Better coverage: the same photo appeared in a news story from another town, three years ago. Pinecrest's weather service reports no flooding today. Final call: WRONG CAPTION. Real photo, wrong place and time.
- Card 6
- Better coverage: the teacher who took it says she added a purple filter for fun. Other photos from the trip show a blue sky. Final call: EDITED, in a harmless way. Ask: "Is every edit a lie?" (No; this one changed the color, not the story.)
- Card 7
- Better coverage: the library's website, the local newspaper, and the town calendar all show the opening on Oak Street on Saturday. Final call: REAL and honest. Checking also tells us when something IS true.
- Card 8
- Better coverage: the singer's tour calendar shows she was performing in another country that day. Lily's cousin admits he pasted the singer in with a photo app. Final call: EDITED. Something was added that wasn't there.
- Card 9
- Better coverage: the principal and the school's website say the playground is fine. No news source reports a sinkhole. The account that posted it has shared other AI-made pictures. Final call: AI-MADE. It never happened.
- Card 10
- Better coverage: the town paper shows the full photo. Next to the cheering crowd is a second group holding signs asking for the skate park to be moved because of noise. Final call: CROPPED. Real, but it hides the people who disagree.
