What is a variable in a scientific experiment?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types in an experiment.

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is a control in an experiment?

Back

A control is a standard against which the results of an experiment are compared; it is the group that does not receive the experimental treatment.

Front

What is a constant in an experiment?

Back

A constant is a factor that remains the same throughout an experiment to ensure that the test is fair.

Front

Why is it important to have a control group in an experiment?

Back

A control group is important because it provides a baseline to compare the results of the experimental group, helping to isolate the effects of the independent variable.

Front

What is the purpose of an experiment?

Back

The purpose of an experiment is to test a hypothesis by manipulating variables and observing the outcomes.

Front

How do you identify the independent variable in a question?

Back

The independent variable is usually the one that is being tested or changed in the experiment.

Front

How do you identify the dependent variable in a question?

Back

The dependent variable is usually the outcome that is measured in the experiment, which changes in response to the independent variable.

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numbers and measurements (e.g., height, weight).
