Scientific Method
17
scientific method : a method of research in which a problem is identified, relevant data are gathered, a hypothesis is formulated from these data, and the hypothesis is empirically tested.
observation : the act of noting and recording something with instruments.
hypothesis : a tentative explanation for an observation or scientific problem that can be tested by further investigation.
experiment : a test under controlled conditions that is made to demonstrate a known truth, examine the validity of a hypothesis, or determine the efficacy of something previously untried.
independent variable : variable whose value is being altered to bring a change in some condition
dependent variable : the observed variable in an experiment or study whose changes are determined by the presence or degree of one or more independent variables
controlled variable : a sample in which a factor whose effect is being estimated is absent or is held constant, in order to provide a comparison.
conclusion : a position reached after consideration of data obtained from an experiment
qualitative data : data described in terms of some quality or categorization that may be informal or may use ill-defined characteristics such as warmth and flavor
quantitative data : data described in terms of quantity and in which numerical values are used.
mass : a property of matter equal to the measure of an object's resistance to changes in either its speed or direction of its motion.
volume : the amount of space occupied by a three-dimensional object or region of space
length : the measurement of the extent of something along its greatest dimension
temperature : a measure of the average kinetic energy of the particles in a sample of matter, expressed in terms of units or degrees designated on a standard scale
metric system : a decimal system of units based on the meter as a unit length, the kilogram as a unit mass, and the second as a unit time.
scientific notation : a method of writing or displaying numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10.
dimensional analysis : a technique that involves the study of dimensions of physical quantities
significant figures : All of the numbers in a measurement that are know to be accurate, plus one that is uncertain.
