Cracking the secrets of Morse Code
Ever wondered how spies talked before smartphones? Let’s tap into the world of Morse Code, where every dot and dash holds a tale waiting to be told.
We’ll explore how Morse Code came to be, how people and animals use it, and how you can send top-secret messages to your friends.
Morse Code is a secret language
It uses dots, dashes, and spaces to send messages quickly over long distances.
Morse Code was invented in the 1830s, along with the telegraph — a machine that worked with electric pulses to mark a paper tape.
Later, Morse Code also became popular with radios.
Secret agents used to disguise special radios as suitcases to spy on their enemies.
Why is it called Morse Code?
Back in the old days…before telephones and the internet, people had to wait for letters that took weeks to arrive. During emergencies, they could only send signals over short distances.
That was until a painter, called Samuel Morse, developed his own telegraph and code system. He gave the code his name.
Mr. Morse didn’t design his code to hide secrets
He wanted to find an easy way for everyone to send messages far away really fast.
But during World War II, Morse Code became popular for sending messages that the enemy wouldn’t understand.
German telegraphers picked the initials S.O.S. It was an easy combination for soldiers to remember when they needed help, even in the heat of danger.
Morse Code is still popular today
Once, Morse Code made a world of a difference for trains, ships, banks, newspapers, families… anyone could send urgent messages through a telegraph office.
Today, the military and emergency helpers save it for when modern technology is down.
But that doesn’t mean that Morse Code is old-school.
Many animals make their own version of the code — like dolphins, woodpeckers, and fireflies. They speak with clicking or knocking sounds, or flashing lights.
There are over 2,000 firefly species and each one has its own code. Read more at: Fireflies talk in their own languages.

Here’s how it works:
Practice by blinking a flashlight, tapping on a table, or writing the code.
The operator (that’s you!), determines the speed of transmission (how long each unit lasts; ex: 1 second).
1 dot = 1 unit
1 dash = 3 units
Space between parts of the same letter = 1 unit
Space between letters = 3 units
Space between words = 7 units
STEP 1: Gather your friends and choose one person as the Morse Code sender and another as the receiver.
STEP 2: Pick a simple message or word to transmit. For example, “hello” or “cat.”
STEP 3: The sender flashes or taps out the Morse Code while the receiver listens carefully.
STEP 4: The receiver deciphers the Morse Code by matching the pattern of dots and dashes with the alphabet.
STEP 5: Once the receiver cracks the message, switch roles.
