Learning Objectives

By the end of this lesson, students will:

1. Understand the role of Morse code in the Titanic disaster.
2. Decode simple messages sent in Morse code.
3. Create and exchange their own Morse code messages.
4. Develop problem-solving skills through historical inquiry.
5. Reflect on how communication has developed over time.

Lesson Structure

1. Introduction (10 minutes) – The Mystery Signal

• Hook: Play an audio clip of a Morse code signal (e.g., SOS sounds — three short, three long, three short). Ask, "What do you think this is?"
• Reveal that this was the distress signal used during the Titanic disaster on 15th April 1912.
• Discuss briefly how wireless communication was used on ships and why Morse code was essential.

---

2. The Story of Morse Code (10 minutes) – A Secret Language

• Display a large chart showing Morse code letters and numbers.
• Explain that Morse code was used to send messages quickly when voice communication was not possible.
• Link to Northern Ireland’s maritime history, e.g., Titanic was built in Belfast.
• Engage students with a quick discussion: "How would we send emergency messages today?"

3. Decoding the Titanic Distress Signal (15 minutes) – The Code Breakers

• Provide students with a worksheet containing a Morse code key and a scrambled version of the Titanic’s actual distress message:

  CQD CQD SOS TITANIC POSITION 41.44 N 50.24 W SINKING NEED HELP QUICKLY

• Students will work in pairs, using the key to decode the message.

• Once decoded, discuss the emergency situation and what it would have been like for those on board.

---

4. Creating & Swapping Messages (10 minutes) – The Code Makers

• Students write a short message in Morse code (e.g., “Help!”, “I need food!”, “Lifeboats here”).
• Swap messages with a partner and decode each other’s messages.
• Encourage them to time themselves to see how fast they can decode.

---

5. Plenary Discussion (5 minutes) – Then and Now

• Reflect: What was it like communicating this way?
• Compare: Discuss how communication has changed from Morse code to modern technology (e.g., mobile phones, satellite signals).
• Final Thought: If the Titanic had modern communication, could the disaster have been different?

---

Resources

• Audio clip of Morse code (SOS message)
• Large printed Morse code chart
• Decoding worksheet with Titanic’s distress signal
• Paper & pencils for creating Morse code messages

Assessment & Success Criteria

✔ Engagement: Active participation in decoding and message creation.
✔ Accuracy: Correctly decoding Morse code words.
✔ Creativity: Inventing messages in Morse code.
✔ Reflection: Thoughtful discussion on communication changes over time.

---

Differentiation

• Support: Provide some letters pre-translated for those needing extra help.
• Challenge: Some students might create longer or multi-step coded messages.

Teacher Reflection

• How engaged were students?
• Did they struggle with decoding, or was it manageable?
• Would audio-based Morse code decoding be beneficial in a future lesson?
