Gather information from fi ve of your classmates regarding the number of songs they have on their iPod or MP3 player. Using the average of these numbers, determine how many CDs would be required to hold the same number of songs. Using the volume of a CD case, the number of CDs required, and the volume of an MP3 player, create a graphic to compare their relative sizes (e.g., 1000 songs on an iPod shuffl e versus 1000 songs on say 100 CDs, assuming 10 songs per CD).
What will be an ideal response?
Assuming a CD case is 5.5”x5”x.25” or 6.875 cubic inches, 100 CDs would
consume a volume of 687.5 cubic inches. The current iPod shuffl e has 4GB
of memory and will hold 1,000 songs. According to the Apple Web site, the
shuffl e has a volume of 0.26 cubic inches or 0.038 percent of the stack of CD
cases.
