Pass It On: Simulating a Computer Network

Overview

Students simulate how computers send messages through networks by passing information along a chain.

Learning Objective
Students understand how information travels through networks from one point to another.

Resources needed

  • No materials required
  • Optional: simple messages

Lesson stages

0 / 10 done
  1. 1 Introduce networks as connected systems.
  2. 2 Explain that messages travel from one point to another.
  3. 3 Students stand in a line or circle.
  4. 4 One student creates a message.
  5. 5 Pass the message along the chain.
  6. 6 Compare original and final message.
  7. 7 Discuss how errors can occur.
  8. 8 Repeat with improvements (slower, clearer).
  9. 9 Introduce idea of data transmission.
  10. 10 Discuss: how do computers send messages accurately?

Tap a step to mark it as done.

Variations

  • Add rules for passing messages.
  • Introduce interruptions or delays.
  • Use written instead of spoken messages.
More information

Teach: network, message, send, receive, transfer. Use frames: 'The message goes…'.

Use gestures instead of speech.

Can students explain how messages travel? Can they identify errors?

Fully unplugged.

Students may think messages always arrive perfectly.

Computer networks rely on accurate data transfer and communication.
