Mystery At Maplewood Academy

To help your group argue better, Maplewood uses a simple rule inside the app’s investigation tools: evidence should be verifiable (you can check it) and relevant (it actually relates to the badge).

Here are the terms your friends will use, and you should too:

• Badge record - the app page that shows the badge status (example: “earned,” “pending,” or “missing”).

• Timestamp - the time and date shown next to an event (example: “12:07 PM, badge removed”).

• Trail - the sequence of events you can follow (example: app update → badge missing → message received).

• Claim - what someone says happened (example: “Someone deleted it.”).

When a badge disappears, your friends might argue like this:

• “My friend said it vanished, so it’s true!”

• “But the badge record doesn’t show that!”

Both are talking, but only one side has evidence.

Step-by-step reasoning you can use

First, check the badge record yourself. Don’t trust only group chat messages.

Second, look for a timestamp. If you can’t find one, your clue is weak because you can’t check the timing.

Third, build a trail. Ask: What happened right before the badge disappeared? Any app message, update, or sign-in event?

Fourth, separate claim from evidence. A claim might be creative, but evidence must be checkable.

Fifth, decide if the clue is relevant. If the clue is about something else (like a different app feature), it doesn’t move the badge mystery forward.

Quick comprehension check

Ask yourself: If someone questioned your clue, could you show where you found it in the badge record?

Practical takeaway: Before you argue, collect one badge record screenshot and one timestamp. Then you can talk like an investigator, not like a guesser.

Worked Example: Checking Evidence When the Badge Vanishes

Here’s what the investigation looks like with real numbers and real decisions - like your friends do in Maplewood.

A badge called “Maplewood Explorer” disappears from the app. Your friend Jada says, “It vanished because of the morning class game.” Noah says, “No way. It happened after someone logged out.”

You need to figure out whose clue is real.

The thinking steps

• Open the badge record in the app and write down what you see.

You find: “Maplewood Explorer: Missing.”

Outcome: You now have a verifiable starting point.

• Check the timestamp on the badge record event.

You see: “12:07 PM - status changed to missing.”

Outcome: Now you can test timing, not just opinions.

• Look for a trail item around 12:07 PM in the app activity.

You notice: “12:05 PM - app refreshed after update.”

Outcome: This connects to a real moment before the badge changed.

• Compare class game timing with the badge timestamp.

The class game ended at about 11:50 AM (your class notes show that).

Outcome: The game is probably not the direct cause.

• Compare logout timing with the badge timestamp.

Noah shows a message: “I logged out at 12:10 PM.”

But your badge changed at 12:07 PM, earlier than 12:10.

Outcome: The logout can’t explain the badge change if it happened later.

• Decide what counts as a real clue.

Your strongest clue is the timestamp + refresh trail: 12:05 PM update refresh → 12:07 PM badge missing.

You write a careful claim: “The badge status changed right after the app refreshed.”

• Handle the argument respectfully.

You tell Jada and Noah: “The app refresh lines up with 12:07. The class game ended earlier, and the logout happened later.”

Outcome: You use evidence to correct the timeline.

Final result: The real clue points to the 12:05 PM app refresh after an update, because it matches the 12:07 PM badge status change. The class game and the logout are weak clues because their times don’t fit.

Practical takeaway: When people argue, you don’t need to win - you need to align claims with timestamps.

Check Your Understanding: Spot the Real Clue

Try these questions. They’re short, but they train your clue-checking brain.

• You see: “Badge missing” on the badge record, but there’s no timestamp. Is this a real clue or a weak clue?

• Hint: Think about whether you can check timing.

• Your friend says, “I think the badge disappeared because of the cafeteria food.” The badge record shows a change at 12:07 PM. What should you ask next?

• Hint: Ask for a trail event close to 12:07 PM.

• Noah claims, “I logged out before the badge changed.” But the badge record shows the change at 12:07 PM and Noah’s logout message shows 12:10 PM. What does that tell you?

• Hint: Compare the times.

• Jada says, “The badge vanished after the morning game.” The game ended at 11:50 AM. The badge changed at 12:07 PM. What kind of clue is the game in this case?

• Hint: Check relevance and timing.

• You find an app activity item at 12:05 PM: “app refreshed after update.” The badge changes at 12:07 PM. Why is this stronger than just “it feels weird”?

• Hint: It’s checkable and connected to the timeline.

Answer Key:

• Weak clue (no timestamp means you can’t verify timing).

• Ask for a trail event near 12:07 PM in the app activity.

• Noah’s claim is likely wrong because 12:10 is later than 12:07.

• A weak clue (timing doesn’t match).

• It’s a real clue because it links to the timestamp and trail.

Practical takeaway: A real clue helps you build a trail with timestamps - weak clues don’t.

Someone in the group chat posts a “perfect screenshot”… but the timestamp looks strange.

When they compare it with the app refresh trail, the mystery badge might not be the only thing missing.

And you’ll have to decide who to trust when evidence starts fighting back.
