Hardness
The term used to describe the things you change or keep the same in an experiment to show cause and effect.
Variables
A measure of how much matter is in an object.
Mass
A physical property or characteristic of some metals such as iron, produced by electric currents, that causes forces between objects, either pulling them towards each other or pushing them apart.
Magnetism
In an experiment this type of variable never changes, it always stays the same.
controlled variable
A state of matter that has a definite shape and a definite volume.
Solid
The degree to which a material reflects light
Reflectivity
In an experiment this type of variable is changed on purpose. It's what you are experimenting on. You only study one of these types of variables in an experiment.
Independent Variable
A state of matter that has no definite shape but has a definite volume.
Liquid
A property of matter that measures how well
something can allow electricity to flow through it.
Electrical Conductivity
This type of variable responds to the changes of the independent variable.
Dependent variable
A state of matter with no definite shape or volume.
Gasses
A property of matter that measures how well something can allow heat to flow through it.
Thermal Conductivity
Variables need to have A)______________, and need to be B)_____________.
