Description: Laboratory Experiments You are asked to study how much table sugar can be mixed or dissolved in water at different temperatures. The amount of sugar that can dissolve in water goes up as the water's temperature goes up. What is the independent variable? Dependent variable? What factor is held constant?

Key Concepts

Dependent Variable

The dependent variable is the measured outcome that is affected by changes in the independent variable. It is what the experimenter collects data on to see if it varies in response to the alterations made in the independent variable. This relationship helps to understand how the changes in the independent variable directly influence the result.

Controlled Variables

Controlled variables are the factors that are kept constant throughout an experiment to ensure that any changes in the dependent variable are solely due to the manipulation of the independent variable. This helps maintain a fair test by preventing confounding influences, thus increasing the reliability and validity of the experimental results.

Independent Variable

The independent variable is the aspect of the experiment that is intentionally changed by the researcher. In the context of experiments, this variable is manipulated to observe its effect on another variable. It is specifically chosen to study its impact on the outcome of the experiment.
