a possible solution or an explanation that is consistent with what is known

organized procedure for testing a hypothesis; tests the effect of one thing on another under controlled conditions

factor that changes as a result of changes in the other variables

factor that, as it changes, affects the measure of another variable

in an experiment, a variable that does not change when other variables change

standard used for comparison of test results in an experiment

represents an idea, event, or object to help people better understand it

an explanation of things or events based on knowledge gained from many observations and investigations

a statement about what happens in nature and that seems to be true all the time

the application of science to help people

an exact quantity that people agree to use to compare measurements

describes how closely measurements are to each other and how carefully measurements were made

compares a measurement to the real or accepted value

a ratio that is equal to one and is used to change one unit to another

the amount of space occupied by an object

a measurement of the quantity of matter in an object

the mass per unit volume of a material

a unit obtained by combining different SI units

a visual display of information or data
