required to do several tests and measurements and then convert these units into other units. There were five tests in all. The first test was measuring the average of three broad jumps in centimeters then find out how many jumps it would take to travel one mile. The second test involved measuring a candy bar (for my group we used a snickers bar) then finding out how many snickers bars end to end it would take to wrap around the equator of the earth. For the third measurement we had to find out how many

Should America convert to the metric system? There are three countries that still didn’t convert to the metric system: US‚ Myanmar (formerly Burma) and Liberia. The US still uses the English units also known as the Imperial System. I think that US should convert to the metric system because: the metric system is much simpler‚ the whole world uses it‚ and the English system hurts the international trade. As I said before the metric system is a LOT simpler! There are 10 millimeters in a centimeter

WESTWOOD COLLEGE Measurement and Criminal Justice Introduction to Physical Science 03/04/2013 It is stated that science can be defined as an organized body of knowledge about the natural universe and the processes by which that knowledge is acquired and tested. Physical science focuses on the study of the nonliving. (Shipman‚ 2013‚2009) Physical science has five branches that it falls under. These branches are Physics‚ Chemistry‚ Astronomy‚ Meteorology‚ and Geology.

Chapter 1 Study of Chemistry -Chemistry is the study of matter and the changes it undergoes. It is a very practical science which means that it can be used to determine stuff we do in real life. For example‚ drugs‚ food‚ etc. are made by researching the chemical properties of the substance. -Matter is anything that has a mass and takes up space -Elements are the most basic substances something can be broken down into. There are about 100 elements known to scientists right now. There may be

modern draft of the metric system‚ Le Système International d’Unités‚ or the International System of Units‚ abbreviated SI. This system was designed to allow countries to trade on a unified system of weights‚ lengths‚ and other forms of measurements. The United States was committed to unorthodox measurements such as feet‚ pounds‚ and gallons. All unstandardized‚ the American units of measurement became unpopular‚ and as nations began to switch to the metric system‚ the United States felt thru pressure
