Document Summary
Chemistry: the science that tries to understand how matter behaves by studying how atoms and molecules behave. Scientific method: a way of learning that emphasizes observation and experimentation to understand the world. Key characteristics that distinguish the scientific method from other ways of acquiring knowledge: observation, hypothesis, testing of hypothesis through experimentation, and the formulation of laws and theories. Combustion: burning; the mass of the object is a measure of the quantity of matter within it. A good hypothesis is falsifiable, which means that further testing has the potential to prove it wrong. Experiments: highly controlled observations designed to validate/show the hypothesis to be mistaken in some way. Scientific law: a brief statement that summarizes past observations and predicts future ones. Law of conservation of mass: in chemical reaction, matter is neither created or destroyed. Theory: one or more well established hypotheses may form the basis of a scientific theory.
