While Morse Code has its advantages (think how it can send a message WAY faster than sending a letter)...it also has its disadvantages. A quick flash of light (representing a dot) can easily be confused with a longer flash of light (representing a dash). A simple misinterpretation can mean the wrong message is sent! |
Over time, codes have changed and improved. Fourth graders are spending the last few weeks of school learning about binary code, and how this digital code is used in many of the technologies that use waves to transfer information. Students will not only learn how to represent numbers in binary, they will also use the idea of a binary code with black and white cards. Since bi- means TWO, they'll be using this base 2 numbering system to help send a code to a friend!
