This is a demonstration that teaches SOS and a Scout's name using Morse code:

First, we explain to the Scouts that Morse code is a system of communication that uses long and short sounds (known as "dots" and "dashes") to represent letters, numbers, and symbols.

Show the Scouts the Morse code chart, which displays the dots and dashes that represent each letter of the alphabet.

Teach the Scouts the SOS signal, which is three short dots, followed by three long dashes, and then three more short dots. Explain that SOS is an international distress signal that is used to indicate an emergency.

Using the Morse code chart, demonstrate how to spell out a Scout's name in Morse code by translating each letter into dots and dashes.

Have each Scout practice sending their name in Morse code using a Morse code key or a phone app that generates Morse code sounds.

Finally, combine the two skills by having the Scouts practice sending an SOS distress signal using Morse code, followed by their own name. For example, they could send "dot dot dot, dash dash dash, dot dot dot, John" to signal an emergency and identify themselves.

By teaching the Scouts how to send an SOS signal and their name in Morse code, they will learn a useful skill that can be used in emergency situations and also develop an appreciation for the history and importance of Morse code in communication.




Morse code is a character encoding scheme used in telecommunication that encodes text characters as standardized sequences of two different signal durations called dots and dashes or dits and dahs. Morse code is named for Samuel F. B. Morse, an inventor of the telegraph.

The International Morse Code (CW) encodes the 26 English letters A through Z, some non-English letters, the Arabic numerals and a small set of punctuation and procedural signals (prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of dots and dashes. The dot duration is the basic unit of time measurement in Morse code transmission. The duration of a dash is three times the duration of a dot. Each dot or dash within a character is followed by period of signal absence, called a space, equal to the dot duration. The letters of a word are separated by a space of duration equal to three dots, and the words are separated by a space equal to seven dots. To increase the efficiency of encoding, Morse code was designed so that the length of each symbol is approximately inverse to the frequency of occurrence in text of the English language character that it represents. Thus the most common letter in English, the letter "E", has the shortest code: a single dot. Because the Morse code elements are specified by proportion rather than specific time durations, the code is usually transmitted at the highest rate that the receiver is capable of decoding. The Morse code transmission rate (speed) is specified in groups per minute, commonly referred to as words per minute.

Though no longer officially used for distress, many scouts enjoy that it's a mode of communication that can be understood with weak or noisy signals and used with flashlights for night-time communications without distrubing others.
