Purpose

What is the fundamental purpose of the device?

The purpose of this device is to make listening to music easier. It allows you to take your favorite music anywhere you want. Besides listening to music you can play games, set an alarm clock, create an address book, watch TV shows, watch movies, watch music videos, and many other items in one simple device. You will never need to cram your purse or book bag with big bulky address books or game devices again.

Energy

What energy transformations are seen in its operation?
The iPod nano itself uses electrical energy and battery powered energy. Battery power is used to keep the iPod alive and playing music. The click wheel of the iPod uses electrical energy too. It send currents to its grid (electric currents). The conductor is the metal parts inside. When you touch the wheel with your finger it helps complete the circuit. The cover part of the wheel keeps the current from reaching your finger (non-conductor). Under the cover the current is building up.

Controls

What sensors/controls are designed into the device?
To change a song of play a game on your iPod you use the click wheel. To use the click wheel only certain materials can make the wheel work. Your finger is an example of a object that will work.
