The Case of the Missing Krabby Patty

Overview

Students investigate how a courtroom helps make fair decisions. After learning key courtroom vocabulary, they take part in a playful courtroom role play to decide whether SpongeBob is guilty or innocent based on evidence, witness statements and respectful reasoning.

Lesson structure (50 minutes)

1. 0–5 min · Hook: Enter the courtroom. Teacher opens the courtroom mystery hook and asks, “Should someone be punished just because people think they did something wrong?” Students silently decide, then share an initial response with a partner. Emphasise that a court must use evidence and fair processes, not guesses.

2. 5–13 min · Key vocabulary. Teacher uses the courtroom roles and vocabulary slides to introduce:

• Judge: leads the hearing and makes sure the process is fair.
• Defendant: the person accused of breaking a law.
• Witness: a person who gives information about what they saw or know.
• Evidence: information that helps people decide what happened.
• Jury: a group that listens to the evidence and decides whether the defendant is guilty or not guilty.

Students repeat each word, match it to its meaning orally and give a possible example. Clarify that “not guilty” means the evidence has not proved the person guilty; it does not necessarily mean we know exactly what happened.

3. 13–18 min · Prepare the case. Teacher explains the fictional case: “The Krabby Patty Secret Formula has gone missing from the Krusty Krab. SpongeBob is accused of taking it.” Distribute the courtroom case file and evidence sheet. Read the case facts aloud and explain that students must only use the clues provided. Assign roles for 19 students: one judge, five jury members, one defendant, four witnesses, two lawyers and seven court reporters/evidence investigators. Students not speaking in court record evidence and questions.

4. 18–30 min · Courtroom role play. Teacher opens the courtroom procedure slides and acts as court clerk/narrator if needed. Follow this sequence:

• Judge welcomes everyone and states the question: “Did SpongeBob take the formula?”
• Prosecution lawyer gives an opening statement.
• Witnesses give short statements from the case file.
• Defence lawyer asks respectful questions.
• Prosecution and defence each summarise their strongest evidence.

The defendant may explain where they were and respond to questions. The teacher pauses when necessary to model, “What evidence supports that?” or “Is that a fact, an opinion or a guess?”

5. 30–39 min · Jury investigation and decision. Jury members review the clues and discuss whether the evidence proves SpongeBob guilty beyond reasonable doubt, using the sentence starter, “We think ___ because the evidence shows ___.” Other students compare evidence on their worksheets and identify one clue that is strong and one that is uncertain. The judge reminds the jury that fairness means listening to all sides.

6. 39–45 min · Verdict and reflection. The jury announces “guilty” or “not guilty” and gives two reasons. The judge thanks participants and explains that real courts may consider consequences when a person is found guilty, but today the focus is deciding fairly. Students compare the verdict with their initial opinion and explain whether their thinking changed.

7. 45–50 min · Exit check. Students complete the final questions on the courtroom case file and evidence sheet: “What is one role in a courtroom?”, “What evidence influenced your decision?” and “Why is it important for courts to be fair?” Invite two or three students to share. Use the traffic-light check-in exit ticket slips for students to show whether they understand the vocabulary and courtroom process.

Resources

• the courtroom mystery, vocabulary, procedure and reflection deck
• the courtroom case file and evidence sheet
• the traffic-light check-in exit ticket slips
• Role labels for judge, jury, defendant, witnesses, lawyers and court reporters
• Chairs arranged as a courtroom
• Pencils and highlighters
• Optional simple props: judge’s name card, toy microphone and evidence envelope

Assessment

• Listen for accurate use of judge, defendant, witness, evidence and jury during vocabulary practice.
• Check whether students distinguish evidence from guesses and support their verdict with information from the case.
• Review the written exit responses for understanding of courtroom roles, fairness and evidence-based decision-making.

Differentiation

• Provide illustrated vocabulary, role cards, sentence starters and a read-aloud of all case information for students needing support or developing English.
• Allow students who are anxious about performing to be court reporters, evidence investigators or jury members; they can rehearse with a partner before speaking.
• Pair confident readers with students who need help, and accept oral responses, drawing or labelled notes on the worksheet.
• For advanced learners, ask them to identify whether each clue is direct or indirect evidence, explain what extra evidence would improve the case, and write a short appeal explaining why the verdict should or should not be reconsidered.

Extension

• Students design one new fair classroom rule and explain what harm it prevents, whose wellbeing it protects and what might happen if it is broken.
• Students write a short newspaper report of the trial from the perspective of the judge, defendant, witness or jury.
