Making a Morse Code

As part of our work on World War Two, we have learnt about the importance of the use of coded messages for communication during the War and how breaking these coded messages was an important part of the Allied victory.  In class today, we used our recently acquired scientific knowledge and skills to design and make a machine that could be used to send secret messages using light, sound or a combination of the two.  Firstly, we worked in small groups to design and draw a labelled diagram of the circuit we would create for our machine.  We then drew a circuit diagram using the appropriate scientific symbols for each of the components.  After this we created our machine and tested that it worked by trying to send messages using Morse Code to each other. We worked successfully as a team and appreciated the resilience it must have taken the codebreakers during the war!
