Lesson: [WIP] EV3 - Telegraph Machine: Introduction

Printer-friendly version
Overview: 
This lesson gives the motivation for constructing a telegraph machine, and shows students how to build one. If there are plans to use the "Morse Code" lesson in this unit, Morse code should not be used as an example for introducing the binary representation of messages.
Objectives: 

By the end of this lesson, students should be able to:

  • Explain why telegrams are represented in binary.
  • Describe how a telegraph machine tramsmits data.
  • Build a functional telegraph machine.

By the end of this lesson, each group should have completed a (mechanically functionally) telegraph machine.
