Transcript of Graduated Cylinder
The Graduated Cylinder is a piece of scientific equipment that measures the volume of water. They can be used in density measurement meaning to measure a solid that is put inside a graduated cylinder than filled with water or the other way, to see how many centimeters the rock measures in water. The graduated cylinder is a easy but a bit hard way of understanding the way to do it. Usually the people measuring with the graduated cylinder (who is the first time they see it) are approximately always looking at the graduated cylinder from the top or holding it in the air. Its says that the scientist likes the graduated cylinder because of it being accurate. The graduated cylinder and measuring cup is mainly used for measuring precisely the amount of water you pour in. The measuring cup is used to measure larger amounts of water, oil ect... If in the kitchen you need small amounts of whatever you have it is best to use the graduated cylinder. Its also that people are scared to use glass because there afraid it breaks but theres plastic. The common size for the graduated cylinder are: 10, 25, 50, 100, 250, 500, 1000ml. Its scientifically proven that millimeters are the best measuring volume for the science object that includes measuring liquid. The graduated cylinder is more accurate than any liquid measuring equipment. The center circle is already explaining some of density but its better to express a bit more of density. Density is referred to how much mass is put in a given volume (a graduated cylinder with already water inside.) Density (in scientific language) is calculated by dividing the mass of a substance by its volume and normally expressed in kilograms per cubic meter, or kg/m^3. The metric system links different measured measurements. The metric volume is measured in cubic meters. it much easier to measure in millimiters because it is already divided for us. Accuracy is one of the most important things in science if each step of a science experiment is accurate it allow to go to the next step of discovering new formulas.
When we could measure density we could know how much water was flowing in the houses,factories and offices so we could have bills, another example in our daily life the bottles of water have been measured so that one bottle is not more than the other.

The water that we drink is measured in density, the water comes from mountains and underground rivers. The water is not 100o/o clean so scientist accompanied chemicals together so the water is drinkable. The factories allow people to have jobs, it also represents lots of money to the cities and factories because the water sold to people pays salaries.
