Morse Code Messaging

(362 ratings )

What You Need:

  • 2 pencils
  • 2 pieces of paper
  • 2 flashlights

What You Do:

  1. Practice by writing out a word or two using dots and dashes for letters, as shown on the chart. You'll quickly see the advantage of keeping messages short and simple.

  2. Write out a short message to your partner in Morse code, while her or she writes one to you. Leave a space between letters. For example:

                ....   .   .__..   .__..   __ __ __
                H   E     L        L             O

 

  1. Take turns using the flashlights to exchange the messages. Use long and short flashes to convey dashes and dots. As you receive your partner's message, jot down the dots and dashes on paper, then decipher them!
