Summary: In this unplugged-style activity, each group will transmit a message to the other groups, using a different code (known to the recipients) and a different communication medium. The aim is to familiarize the participants with the concept of information representation and especially digital binary representation. At the same time, the part of the activity pertaining to message transmission introduces important issues regarding the role of symbols in each code, as well as the role of the physical carrier used for transmitting or storing information.
Goals: Associate representations that employ the symbols 0 and 1 with other, more familiar, binary representations, thus establishing a view of the former as yet another binary representation. Highlight the physical form of information in the systems that transmit, store or process this information.
Duration: at least 30 minutes
