Part of Lesson Plan: Binary 1- Calm Down, It's Only Ones and Zeroes- How Computers Think.
Activity Overview / Details
When you start the lab, the teacher should have an old-style record player as a demonstration. A gramophone would be best, but probably too expensive. Any old turntable will do, with a player built out of a paper cone and a needle as demonstrated in this video:
Use the record player to demonstrate how you can create music without any electricity. Spin the record player, put the needle on the record and have them listen to the music coming out of the paper cone. Explain to them how the music is created by the needle wiggling back and forth in the record groove, which vibrates the paper and re-creates the sound that was used to originally make the groove. The groove is shaped like an “analogy” of the original music.
