Density |
Mass per unit volume of a substance, can be expressed as grams per ml or grams per cubic cm |
|
|
|
Dependent Variable |
What the researcher observes in the experiment, also called the reponding variable |
|
|
|
Experiment |
A test designed to demonstrate the validity of a hypothesis |
|
|
|
Independent Variable |
What the researcher manipulates or purposefully changes |
|
|
|
Law |
A scientific rule that decribes the behavior of natural phenomena |
|
|
|
Mass |
The amount of matter in an object; measured in grams (g) |
|
|
|
Results |
The data collected during an experiment expressed in paragraph form |
|
|
|
Theory |
A well-tested and widely accepeted view that explains certain observable facts |
|
|
|
Volume |
Amount of space occupied by a material or subtance; measured in milliliters (ml) or cubic centimeters (cc) |
