Unlocking the Secrets of Secret Codes with a Snake?

Sending messages in secret code has fascinated leaders, warriors and young people over the centuries. You will build your own coding machine using cardboard to code and decode secret messages sent by other children in the group. After some practice with pencil and paper, you will turn to Python - the program (not the snake).

Working in a team, you will plan a program to encode a message and then write and debug your program. Of course, there is no one right solution: with your partner you will present your solution.

We will look at strategies for breaking codes. You will evaluate brute force and pattern spotting as methods of cracking simple codes.

Fortunately you won't learn enough about cryptography to get yourself into trouble but you will have the opportunity to learn the basics.
