In a reaction chamber is located a platform for receiving individual samples/sample racks. The reaction chamber can be heated, cooled and evacuated. The samples are then radiation heated. . The individual sample containers/reaction containers can be filled or emptied in use of ducts thoroughly. The system has applications in the field of chemical combinatory synthesis, as evaporator or for related applications. Reaction chambers are commonly heated from the bottom platform.

 * RESEARCH**

A chamber is a natural or artificial enclosed space. - there are many types of chamber.There even are chambers in our own body like the heart chamber. Scientist use chambers very frequently for multiple things, specially do prevent things to come in contact with other things. They must frequently use it for expirementes. -You can light a match in chamber by using a candel. wordnetweb.princeton.edu/perl/webwn Mirna Maradiaga
 * Chamber Research**

A reaction chamber is a closed spaced used to perform reactions in a safe way. Closed reaction chambers keep all reactants in the same space while they react. To ignite a match in a closed reaction chamber you should add heat and energy constantly, enough activation energy shall be added for the match to ignite. This could be accomplished by using any object realeasing a certain amount of energy. [] - Carlos Varela.

How does a balance Work?

When two objects are at each end of the arm of the balance, there is when it works. It works by being tilted by the heavier object and the lighter object is suspended up. []

Constructing a Balance.. A balance can be constructed using wood. Two long and narrow sticks facing each other vertically and putting the balance arm horizontally with a nail between them makes it as a balance.

 * BALANCE POSTS:**
 * A:**// A balance is a piece of equipment used to measure mass and/or weight. Balances come in many shapes and sizes, but the most common are those that consist of a plank and a base on which the plank rests. Balances may be used to determine both weight and mass, and were the first weight measuring systems.
 * A:**// A balance works by balancing two weights on each extremity of the balance. If one of the objects weighs more, that "arm" will be lower than the other one. INFO SOURCE

A balance scale is used to perform precision measuring and weighing. Other types of scales are affected by gravity and, depending upon geographic location, can vary in their results. Balance scales do not have this issue because they are balanced, which implies both sides of the scale are affected exactly the same. Balance scales are also referred to as beam balances or laboratory balances. The scales that the statue of Justice holds are traditional balance scales consisting of a horizontal beam (lever) with a scalepan, or scale of equal size and weight, hanging from each end of the beam.

How is a balance constructed? The balance scale was the first instrument ever invented for measuring weight and mass. It consists of a beam and two scales, or flat pans, suspended from either end. The beam is set on a point so that both arms are of equal length. []

This is an example of a toy balance which we could use as inspiration for our project. We could use this as an example and make a similar model with this mechanism: a pole attatched to a rotating piece of wood at which we could tie the baskets to weigh the objects.

 * What is a balance: According to diccionary.com "an instrument for determining weight, typically by the equilibrium of a bar with a fulcrum at the center, from each end of which is suspended a scale or pan, one holding an object of known weight, and the other holding the object to be weighed." []
 * How to construct a balance: In the following website you will find a procedure of how to make a balance. The interesting thing about this balance is that grocery men use this balance to weigh their goods and stuff and I believe it may work for this project! http://www.campsite24.ca/balance_scale_eng.pdf
 * A balance looks something like this: [], [], [], and a forth picture of the balance is located in the URL of the "consturct a balance" bullet.
