Document Summary
Experiment= an observation of natural phenomena, carried out in a controlled manner so that the results can be duplicated and rational conclusions obtained. Law= a concise statement or mathematical equation about a fundamental relationship or regularity of nature and is extremely well tested. Must be a theory before it becomes a law. Hypothesis= tentative explanation of some regularity of nature after basic experimentation is done. Theory= well tested explanation of basic natural phenomena after the original hypothesis as successfully passed many tests. Form a new hypothesis is there are negative results. Support the hypothesis if there are positive results. Theory after the results are consistent after multiple experiments. Further experimentation until it becomes a law. Matter= whatever occupies space and can be perceived by our senses. Law of conservation of mass= total mass remains constant during a chemical reaction. Insisted on the use of balance in chemical research. Demonstrated the law of conservation of mass.
