This term 4th class learnt about communication and last week we learnt about the history of sound recording.  We listened to a portable grammophone that belonged to the teacher’s  grandmother and was about 100 years old.  You wound a handle and the disk would start turning.  After that you would put the arm that had a speaker and a needle onthe disk and it would start playing music.
