Mass
________: a measurement of the quantity of matter in an object.
Hypothesis
________: a possible solution or an explanation that is consistent with what is known.
Conversion Factor
________: a ratio that is equal to one and is used to change one unit to another.
Model
________: represents an idea, event, or object to help people better understand it.
Line Graph
A(n) ________ can show any relationship where the dependent variable changes due to a change in the independent variable.
Science

Theory
________: an explanation of things or events based on knowledge gained from many observations and investigations.
Variable
________: factor that can cause a change in the results of an experiment.
Hypothesis
a possible solution or an explanation that is consistent with what is known
Experiment
organized procedure for testing a hypothesis; tests the effect of one thing on another under controlled conditions
Dependent Variable
factor that changes as a result of changes in the other variables

factor that, as it changes, affects the measure of another variable
Constant
in an experiment, a variable that does not change when other variables change
Control
standard used for comparison of test results in an experiment
Model
represents an idea, event, or object to help people better understand it
