Purpose
Yes, the television was created for entertainment. But is also a way of getting information across to the public like news stories and weather. For example, the news is there to educate us about important decisions happening around the world, and the weather is there to tell us a message of how the day is going to be in advance so we are able to make plans if wishing to go out to travel.

Energy
The energy transformation taking place is the transfer from electrical energy to sound energy. Energy Transfer is the process of transferring energy from one body to another.

Controls
The controls for a plasma screen TV normally consist of a receiver of some kind. Some could be built into the TV, or they could also be outside the TV in a kind of cable box.

Materials
Normally, a cable box and remote are necessary materials that come along with the use of a television.

Science
The scientific principle of the plasma screen TV include the transfer of energy from the remote to the TV. The TV's receiver must pick up infrared signals coming from the remote, to direct or tell the TV what to do.

Design
Typically, a plasma screen television has a black screen, and can either be hung on the wall, built into things, or stand alone. It normally has a stand, and has plugs in the back, for many reasons.

Evolution
With advances in technology, plasma screen televisions have gotten smaller, and now they are made as high definition televisions. Many changes have been made in either improve them, or make them look better. For instance, they have been made to stand by themselves, hang on walls, or are built into things. They have also been made to have the picture look nicer. Instead of just having high definition channels from cable, you now can buy an HD television without having to also have the certain type of cable.
