 Scientific method a logical approach to solving problems by observing and collecting data, formulating hypotheses, testing hypotheses, and formulating theories that are supported by data System a specific portion of matter in a given region of space that has been selected for study during an experiment or observation Hypothesis testable statement (basis for making predictions) model an explanation of how phenomena occur and how data or events are related theory a broad generalization that explains a body of facts or phenomena quantity something that has magnitude, size, or amount SI Le Systeme International d' Unites-the measurement system accepted worldwide weight a measure of the gravitational pull on matter derived units a unit that is a combination of SI base units volume the amount of space occupied by an object density the ratio of mass to volume, or mass divided by volume accuracy refers to the closeness of measurements to the correct or accepted value of the quanity measured precision refers to the closeness of a set of measurements of the same quantity made in the same way (not close to accepted value) percent error a value calculated by subtracting the experimental value from the accepted value, divinding the difference by the accepted value, and then multiplying by 100 significant figures a measurement consist of all the digits known with certainty plus one final digit, which is somewhat uncertain or is estimated conversion factor a ratio derived from the equality between two different units that can be used to convert from one unit to the other scientific notation numbers are written in the form M x 10n where the factor M is a number greater than or equal to 1 but less than 10 and n is a whole number (exponent) directly proportional two quantities that give a constant value when one is divided by the other inversely proportional two quantities that have a constant mathematical product
