Lesson focuses on exploring electric message systems, from light signals using
International Morse Code to text messaging. Students construct a simple telegraph using
a battery, wires, a switch, and bulb, and explore the impact of communications on

The Electric Messages: Then and Now activity explores electronic communication, the
Morse Code system, and advances all the way through text messaging. Students build a
simple circuit, send messages to one another, and explore the impact of electrical
communications on society.
A g e L e v e l s
O b j e c t i v e s
Learn about electrical based communications.
Learn about the Morse Code system.
Learn about wiring, switches, and simple circuits.
Learn about teamwork and problem solving.

A n t i c i p a t e d L e a r n e r O u t c o m e s
As a result of this activity, students should develop an understanding of:
audio and visual applications of International Morse Code
electrical wiring, simple switches
L e s s o n A c t i v i t i e s
Students learn about how to send Morse Code through electrical simple switches which
they construct from batteries, wires, and a bulb. They explore the impact of electrical
communications on society and therefore the value that engineers add to our world.
