What term best describes a variable that stays the same throughout an experiment?

Answer 1

The independent variable.

The independent variable is an excellent answer, for sure, but you might also consider

a constant variable, ie a variable whose value can not be changed once the experiment has begun, but can be changed in subsequent experiments.

For instance, we want to determine the rate at which an ice cube melts at various room temperatures. The latent heat of liquefaction does not change for water (ice) no matter the room temperature, but the rate at which that heat will be absorbed by the ice cube does change depending on the amount of heat available in the room (the room temperature).

So the latent heat of liquefaction is a constant, while the temperature of the room is a variable (because we can change it), but for each individual experiment the room temperature remains constant throughout, so it becomes a constant variable.

Answer 2

Potential variables that are kept the same during an experiment are control variables.

The values being altered and tested are experimental variables.

Answer 3

The variable that stays the same is called the constant.

Answer 4

The controlled variable is the variable that stays the same throughout the whole experiment.

Answer 5

Whatever you want. For example: s, sm, tsm, the_same...

Answer 6

Controlled Variables

Answer 7

it is constant

Answer 8

time

Answer 9

constant
