In zoology, a scale is a small, hard plate that grows out of an animal's skin to give it protection. Fish and reptiles have scales.
In animals such as butterflies and moths, scales are plates on the surface of the insect wing. They are often beautifully coloured.
Weighing scale
Scales are used to measure the weight of an item. To use a scale, the item which needs to be weighed is put on one side of the scale. Then, weight stones are put on the other side. Once the scale balances (that is the indicator between the two scales is in the middle), the correct weight is chosen.
There are also modern scales, where the item is simply put on the scale. Its weight can then be read from an electronic or analogue display.
Weighting Scales are used to measure the weight of an item. To use a scale, the item which needs to be weighed is put on one side of the scale. Then, usually stones are put on the other side to compare the weight of the stone with the weight of the object you have chosen. If both cups are in the middle, it means that the weights of the objects are equal. If one cup is more up while the other one is down, it means that the one that is down is the heavier one. For example: If you place a small stone in one cup, and a watch in the other cup, and the cup with the watch goes down and the stone obviously goes up, it means that the watch has a greater weight than the stone.

STS-122
STS-122 is the name of the 121st flight of the Space Shuttle, taking seven people into outer space to visit the International Space Station. The flight delivered a module to the space station, called "Columbus". The Space Shuttle "Atlantis" carried the module. The flight started at 19:45 UTC, on 7 February 2008, from the Kennedy Space Center in Florida. The flight ended on 20 February, at 14:07 UTC, when the Shuttle went back to the Kennedy Space Center.
Seven people were aboard the Space Shuttle. They are; Stephen Frick, who was the Commander, the man in charge of the Space Shuttle, Alan G. Poindexter, who was the Pilot, the man who flied the Shuttle, Leland D. Melvin, Rex J. Walheim, Hans Schlegel and Stanley G. Love, who were there to fit the "Columbus" onto the space station. Léopold Eyharts was also on board. He lived on the Space Station for a month. Daniel M. Tani, who was on the space station came home aboard the Soyuz spacecraft.
The flight was originally scheduled to launch, on 6 December 2007. A problem with a part of the fuel tank used to work out how much fuel was left went wrong, which meant the start of the flight had to be delayed. After the same part went wrong in an attempt to start the flight on 9 December, the start of the flight was moved to January 2008, and later to February. The flight started on 7 February 2008. Some people at NASA were worried that bad weather might stop the launch, but the bad weather cleared up in time for a good launch.
At 13:00 UTC, a 2-minute-43-second de-orbit (opposite of making an orbit) burn was conducted. Then it entered in the atmosphere at 13:35 UTC. "Atlantis" touched down on Runway 15 of the Kennedy Space Center at 9:07:10 EST (14:07:10 UTC). The wheels of the orbiter stopped at 09:08:08 EST (14:08:08 UTC).
The people aboard STS-122 had several jobs to do. The main job was to add the new room, or module, "Columbus", to the space station. To do this, a robot arm, called a Remote Manipulator System, or RMS, will be used to lift "Columbus" out of the Space Shuttle, and move it over to a gap in the side of the space station. Two of the crew will then go outside, and fit parts to the module. "Columbus" will be used for scientific research.
