Scientific Variables

Front

What is a dependent variable?

Back

The dependent variable is the outcome or effect that is measured in an experiment. It depends on the independent variable.

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or manipulated in an experiment to observe its effect on the dependent variable.

Front

What are constants in an experiment?

Back

Constants are the factors that remain the same throughout an experiment to ensure that the test is fair.

Front

What is the purpose of control variables?

Back

Control variables are kept constant to prevent them from influencing the outcome of the experiment.

Front

How does changing the independent variable affect the dependent variable?

Back

Changing the independent variable can lead to changes in the dependent variable, which is what the experiment aims to measure.

Front

What is an example of a dependent variable in a plant growth experiment?

Back

The growth of the plant is the dependent variable, as it is affected by the type of liquid given.

Front

What is an example of an independent variable in a bubblegum experiment?

Back

The brand of bubblegum is the independent variable, as it is what is being changed in the experiment.

Front

Why are constants important in an experiment?

Back

Constants are important because they help ensure that the results are due to the independent variable and not other factors.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.

Front

What is a control group?

Back

A control group is a standard for comparison in an experiment, where the independent variable is not applied.
