Control

Density
The state or quality of being dense : compactness: closely set or crowded condition. (thickness)
Dependent Variable

Experiment
A test, trial, or tentative procedure
Graph
A diagram that represents the variation of a variable in comparison with that of one or more other variables.
Hypothesis

Scientific Method
The method that science used to investigate. Also when a hypothesis is tested.
Standard
an object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity. (a reference that is used to calibrate measurements)
Technology
The application of scientific knowledge to the practical aims of human life
Scientific Theory
An explanation of things or events based on knowledge from observation and experiments.
Variable
A quantity that can have more than one value.
Volume
The quantity of three-dimensional space occupied by a liquid, solid, or gas.
SI (International System of Units)
