Mass: Kilogram.

Liquid volume: The basis of fluid volume units for the metric system is the liter. A liter is about the same as one quart.

• The independent variable in an experiment is the variable whose value the scientist systematically changes in order to see what effect the changes have.

• A dependent variable is what the experimenter observes to find the effect of systematically varying the independent variable.

• Experimental constants are values that do not change either during or between experiments.

• A controlled variable is a variable that could change, but that the experimenter intentionally keeps constant in order to more clearly isolate the relationship between the independent variable and the dependent variable.
