1.)Empedocles theory-Empedocles' philosophy is best known for originating the cosmogenic theory of the four classical elements.

2.)philosopher's-Philosophy of science is a branch of philosophy concerned with the foundations, methods, and implications of science.

3.)Theories-A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world.

4.)gases-A gas is a sample of matter that conforms to the shape of a container in which it is held and acquires a uniform density inside the container, even in the presence of gravity and regardless of the amount of substance in the container.

5.)Philosopher's stone-an imaginary stone, substance, or chemical preparation believed to have the power of transmuting baser metals into gold and sought by alchemists; broadly : an elusive or imaginary key to success —called also philosophers' stone.

6.)experiments-a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact

7.)chemicals-a compound or substance that has been purified or prepared, especially artificially

8.)chemistry-he branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change;

9.)periodic table- The table of chemical elements arranged in order of atomic number

10.)fields-The branches of science

Where did I get my information from?
I got it from the discovering atoms online book

The book I chose to do my report on is Discovering Atoms.This book talks about the ancient theories, people, and countries they came from. The Greek philosopher Democritus, said “that matter is made up of solid atoms and empty space”. This was back in (460-370 BCE) so he was ahead of his time and proved his theory.Materials could be broken apart because of the spaces exist between the atoms that compose the materials.The ancient philosopher Aristotle (384-322 BCE) did not accept Democritus’s atomic theory.Aristotle preferred Empedocles theory of the four elements.Aristotle is generally regarded as the greatest thinker of his age.Yet many historians believe that Aristotle’s dismissal of “anatomist” is the main reason scientific inquiry into the nature of matter was stalled for nearly 1,500 years after his death.Alchemists and the emerging  field of chemistry. Alchemy was the attempt to transmute,or change,one substance into another.It was a direct outgrowth of Aristotle's concept of the transmutation of elements. Alchemists called the agent of transformation the “philosopher’s stone” ,a mysterious chemical preparation that they believed could alter the nature of substances.Issac Newton (1642-1727) he supported the Democritus atomic theory of matter because he provided the first real evidence for it. The first real breakthrough in the area would come through the study of gases.He also believed that writings contained genuine secret wisdom that provided the key to understand the whole universe.The Irish chemist Robert Boyle(1627-1691)was one such researcher.Boyle's law,as it is now proved that gas pressure and volume are inversely related. It was very important discovery because this is the way a gas would behave were composed of a mass of freely moving particles and for that the gas can expand.The theory of phonologist was debunked by a contemporary of Lavoisier,the eccentric English scientist Henry Cavendish(1731-1810).He conducted an experiment in which he added acid to metal,expecting the phonologist would be produced by the reaction.Lavoisier was ecstatic when heard about Cavendish's results.He repeated the experiment and announced to the world that water was a compound a material made up of two gases chemically combined.One gas he knew was oxygen and he named the other gas hydrogen(in Greek the word means water producer).Lavoisier announced that water was an oxide of hydrogen,not one of Aristotle’s fundamental elements.Thus began the era of modern chemistry.Today the periodic table contains 118 chemical elements whose discoveries have been confirmed-four of those are naturally occurring,while twenty-four of them are synthetic,having being produced artificially in labs and usually only existing for milliseconds.Since 1999,six elements have been discovered and confirmed but not yet named.They have received temporary names which are in Latin words for their atomic number.This book was really good because it gave the names of the scientists and what they did and their theories .Reading this book and doing this project really made me realized the science field is huge and not just about one certain field but hundreds.There’s so many theories and experiments to go along with science you will learn something new everyday.
