Students in Mrs. Ash’s 5th grade recently learned about the power of radio and its vital role as a communications tool over the past 100 years. As part of their Language Arts class, the students read a story about the Navajo Codetalkers during World War II who used a secret code through radio transmissions to help win the war. To expand on the lesson, Mrs. Ash invited Don Mazak, grandfather of 5th grader Alex Mazak, to share his knowledge and passion for radio communication with the class. Mr. Mazak was a communications specialist for the U.S. Army during the Vietnam War and is an avid ham radio hobbyist. For his February 16 class presentation, Mr. Mazak brought in various transistors to demonstrate the Morse Code and talked about how people around the world today are able to communicate via ham radios.
