Young Adult Programs

Crack the Code

Length of Program

1-2 hours, depending on the number of participants and computers.

Program Description

Secrets appeal to teenagers, and codes and ciphers are always popular. This program combines technology and intrigue. It can also be developed without computers if access is limited. Teens will learn to create a simple cipher that substitutes one symbol for every letter, using the Microsoft Webdings font. They will explore Morse code and other codes, and integrate mathematics with entertainment.

Preparation

For the program, teens will need access to a computer that has the webdings font. Each participant will need a copy of the webdings fonts to create their own code. It is available on the My Fonts Web site at www.myfonts.com/fonts/microsoft/webdings/webdings/ charmap.html. Teens use the worksheet to assign a symbol to each letter of the alphabet. Remind them that they need to create a “cheat sheet” for the code so that they and their friends can crack their codes. If you don’t have access to enough computers, incorporate some paper puzzles and math games into your program.

Web Sites

Cryptogram Maker
www.kidzone.ws/puzzles/cryptogram/
On this site, teens can solve randomly generated cryptograms from a pull down list of themes, or build a cryptogram for another user by entering a phrase in a box and letting the program do the work for you.


Morse Code and Phonetic Alphabets
www.scphillips.com/morse/
Use this site to print out a chart of the international Morse code characters, use a Java Morse code translator to translate to and from Morse code, or get answers to frequently asked questions about Morse code. You can also hear Morse code on your computer once it has been translated on the site.


Navajo Code Talker’s Dictionary
www.history.navy.mil/faqs/faq61-4.htm
The Navajo Code Talker’s program was established during World War II and not one cryptologist could crack it. The Code was declassified by the Department of the Navy in 1968. This site contains the Navajo Code Talker’s Dictionary. It includes the letter of the alphabet, the corresponding Navajo word written phonetically, and the literal translation of the Navajo words.
