Constant

Control

Density
A measure of mass per unit of volume
Dependent variable
It is something that depends on other factors.
Experiment
A scientific test in which you perform a series of actions and carefully observe their effects in order to learn
Graph
A graph is a set of vertices and a binary relation between vertices, adjacency.
Hypothesis

Mass
A fundamental property of all matter.
Model
A physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes.
Scientific Method
Principles and procedures for the systematic pursuit of knowledge involving the recognition and formulation of a problem.
Scientific Law
The description of an observed phenomenon
Standard
An object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity.
Technology
Knowledge put into practical use to solve problems or invent useful tools.
Scientific theory
Carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method.
Variable
Anything that can change or be changed.
Volume
The amount of space occupied by a three-dimensional object or region of space.
SI
A complete metric system of units of measurement for scientists
