Do you have a kid who’s into breaking codes, secret spies, or special agents? I do! Our Morse Code activity below is perfect for home or in the classroom, and the kids will love finding out how to send secret messages in Morse Code. Solving codes is a neat way to make STEM fun!

FUN FACTS ABOUT MORSE CODE

WHAT IS MORSE CODE?

Morse code is named after Samuel Morse, one of the inventors of the electrical telegraph.

A telegraph is a long-distance communication system where a message is sent via a code, rather than the physical exchange of the message. It is a form of communication in which sounds, or signals, are used as letters!

Morse code was a way to communicate a message with only electrical pulses and the silence between them. The telegraph operator would encode a message and use a machine to tap out the signals to send that message.

It was used from the 1840s to the late 20th Century, and its invention completely changed long-distance communication.

There are two sounds or signals used in Morse code, which are written as dots and dashes. The dash is a longer sound, and the dots are very short sounds.

Each letter of the alphabet is formed by a sequence of dots and dashes. There is no difference between upper and lower case letters. The length of a dash is three times that of a dot.

To make it easier, Morse code was designed so that the most frequently used letters in the alphabet have the least number of dots and dashes. For example, the letter E is one single dot.

Morse code has been in use for more than 160 years now. The Morse code used today though is very different from the Morse code that was originally developed by Samuel Morse and Alfred Vail.

The distress signal SOS is one of the most well-known signals in Morse code. It is three dots followed by three dashes, and then three dots again.

Morse code can be sent by sounds or light (like a flashlight) and is easier to learn by hearing or seeing rather than by reading. Sailors on ships can flashlight in Morse code to send messages from one ship to another.

The telegraph used electrical current bursts to carry the message, but you can use your flashlight to send a message in Morse code to a friend! Give it a try!

HOW TO LEARN MORSE CODE

Morse code is fun to learn! Have a go, and don’t give up if it takes a bit of practice!

SUPPLIES:

INSTRUCTIONS:

STEP 1: Print out the two code keys and worksheet.

STEP 2: Write a simple message or your name on the worksheet. Don’t show your friend your message.

STEP 3: Sit in a dark room across from each other.

STEP 4: Use the morse code key to send your message using your flashlight. Flash the light one second for each dot, and 3 seconds for each dash. Go slowly so your friend can interpret each letter.

STEP 5: Now it’s your friend’s turn to send a message to you! Have fun sending each other ‘secret’ messages!
