In the course "Secret Scripts", children explore the fascinating history of writing as a means of communication and documentation. They learn basic principles of encryption – from simple monoalphabetic methods such as the Caesar shift to more complex polyalphabetic methods and transposition techniques. They engage with writing not only in a receptive way but also creatively and productively. Together, they decipher historical writing systems such as Ugaritic cuneiform and work with tools like the scytale staff and the Alberti cipher disk. A special highlight is the hands-on construction of a functional Morse apparatus, enabling them to send their own messages via a simple electrical circuit.
