Titanic's Distress Signals

Curriculum Area and Level

Area: Technologies
Level: Second Level (Aligned with Scotland's Curriculum for Excellence)
Experience and Outcome: TCH 2-01b – "I understand how technologies help communicate and provide information and I can apply this knowledge in different ways."

Lesson Duration

Total Time: 90 minutes
Class Size: 25 students
Age Group: Year 5 (ages 9-10)

---

Learning Objectives

By the end of the lesson, students will:

• Understand how communication technology was used on the Titanic.
• Identify key distress signals (e.g., Morse code, wireless telegraphy).
• Explore how communication technology has evolved since the Titanic.
• Work collaboratively to create and decode distress signals.

---

Resources Needed

• A printed or projected Morse code chart
• Audio recordings of Titanic’s distress signals (teacher to play)
• Small flashlights for Morse code activity
• Whiteboards and markers
• A large world map (to track Titanic’s route)

Lesson Breakdown

1. Introduction – Setting the Scene (15 minutes)

• Engage: Begin by asking, "How do we send emergency messages today?" (e.g., phones, radios, emergency sirens, satellites).
• Discuss: Explain that in 1912, when the Titanic sank, technology was very limited.
• Show Visuals: Display an image of the Titanic’s Marconi radio room. Discuss the importance of wireless telegraphy at the time.

Challenge Question: "What would happen if people on the Titanic had no way to communicate?"

---

2. Titanic’s Distress Signals (20 minutes)

• Explain: The Titanic used Morse code to send distress signals. Two key messages were:
  • CQD CQD SOS SOS – this was one of the most famous emergency signals ever sent.
  • The Titanic’s location: 41° 46' N, 50° 14' W
• Play Audio: Let students listen to a reenactment of the actual Morse SOS message.
• Group Discussion: Ask, "Why was SOS chosen as an emergency signal?" (Simple to understand, clear in emergencies).

3. Morse Code Activity – Sending Signals (30 minutes)

Part 1: Learning Morse Code (10 minutes)

• Hand out Morse code charts, and let students write their names in Morse code.
• Pair students and have them decode each other’s names.

Part 2: Flashlight Communication (20 minutes)

• Setup: Dim the lights slightly. Each group gets a flashlight.
• Task: One student will "send" an SOS signal to their group using a flashlight. The group must decode and write down the message.
• Discussion: Compare how long it took different groups to decode messages.

Challenge Question: "How does Morse code compare to modern emergency communication?"

---

4. Connecting to Modern Communication (15 minutes)

• Compare Then vs Now: Discuss how we communicate emergency messages today (radios, satellites, distress beacons).
• Interactive Reflection: Ask students to act as future inventors:
  • "How would you improve emergency communication for ships today?"
• Group Share: Have students present their ideas to the class.

---

Plenary – Wrap Up Discussion (10 minutes)

• Quick Fire Quiz: Ask students:
  • “What signal did the Titanic send?”
  • “What did SOS stand for?”
  • “How did Morse code work?”
• Exit Ticket: Each student writes down one new thing they learned.

---

Assessment and Reflection

• Formative Assessment: Observe participation in the activities, engagement with Morse code, and contributions to discussions.
• Reflection Question: Ask students to write or discuss “Why is effective communication important in emergencies?”

---

Extension Task (Optional)

• Home Challenge: Students create their own short Morse code message and ask a family member to decode it.
• Creative Task: Design a "What If?" scenario – What if the Titanic had modern communication technology? How might the story have changed?

---

Teacher Notes

• Ensure all students have a chance to participate in the flashlight activity.
• Adjust pacing based on student engagement.
• Encourage curiosity by linking Titanic’s signals to modern communication they use daily.

Why This Lesson Stands Out

• Interactive and Engaging: Moving beyond textbooks to hands-on communication challenges.
• Historical Relevance: Real-world connections between past and present technology.
• Higher-Level Thinking: Encourages innovation by asking students to improve emergency communication.

🚢 A lesson that truly brings history and technology to life!
