Interview your parents to determine what type of audio media they have (CDs, vinyl records, and so on), and how many of each kind.

What will be an ideal response?


Most parents likely have their music collection primarily on CDs and at the same time are in the process of transitioning to a digital media player, such as an iPod. In addition to CDs and an MP3 player, most parents will probably have an extensive vinyl record collection. Unfortunately, the majority of these collections are sitting collecting dust as the convenience and portability of CD and MP3 players has made vinyl records and turntables obsolete. An interesting extension to this exercise could include aggregating the data from the entire class and creating a table detailing number of CDs, MP3 players, vinyl records, and turntables.
