Secret Codes by Meredith Yeager, Research Associate, IHMC

February 24, 2024

February Science Saturday was about secret codes and cryptography. Students encoded and decoded messages using techniques like mirror writing, the Caesar Cipher, the Pigpen cipher, and others. They learned how the Caesar Cipher was eventually broken using frequency analysis, based on how often each letter typically appears in text in a given language. For the final activity, students worked in two teams to decode a series of messages in order to find the solution to an escape-room-like scenario.
