Operation: Teen Code Raiders
by Victor Shill
50 – 90 minutes
Not all codes are intended to be secret. In this program, teens learn about communication through Braille, Morse Code, or sign language.
Invite qualified individuals from the community to demonstrate Braille, Morse Code, and sign language. As an alternative, librarians may use the suggested web sites and books to present an introductory program.
Display examples of Braille, morse code, and sign language. Create a display based on the movie, Lara Croft: Tomb Raider, an adventure story in which the heroine must battle a secret society for an ancient artifact possessing great power. Ask teens to help create the display, using pictures, for example, depicting tombs, pyramids, hieroglyphics, runes, astrological symbols, medieval castles, and gargoyles.

Let teens learn to sign their first name using the sign language alphabet or practice sending a message by morse code.
Form the teens into pairs. Give each team a piece of paper containing a short, simple phrase. Let them learn to sign it. Each pair will stand in front of the others and sign their phrase. Give a prize to the first teen to “read” it correctly.
Create a secret code message such as “Reading Is Fun” or “Your mission is to read.” Display the message on the bulletin board and have a contest to see who can be the first to solve it.
Acronym Challenge. Ask teens to find the meaning of the following acronyms: CIA, OSS, NSA, MI6, KGB, CI, FBI, IC, DOS, UNCLE. Direct them to the Acronym Database at www.ucc.ie/acronyms/ and to books in your library to locate the answers.
Let teens squeeze the juice of a lemon onto a plate and dip a toothpick or small brush into the juice to write an invisible message on paper. After the juice dries, they hold the paper against a hot light bulb and read the message.
