Intent of Experiment - Types of Variables

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

In an experiment, what is the control variable?

Back

Control variables are the factors that are kept constant to ensure that the results are due to the independent variable only.

Front

Example of an independent variable in a plant growth experiment?

Back

The type of liquid given to the plants (e.g., water, apple juice, milk).

Front

Example of a dependent variable in a distance rolling experiment?

Back

The distance the ball rolls off the ramp.

Front

What is the purpose of having control variables in an experiment?

Back

Control variables help to ensure that the experiment is fair and that the results are valid.

Front

How does changing the independent variable affect the dependent variable?

Back

Changing the independent variable will cause a change in the dependent variable, which can be measured to determine the effect.

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

Why is it important to identify variables in an experiment?

Back

Identifying variables helps to clarify the focus of the experiment and ensures accurate data collection.

Front

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

Back

The amount of sunlight each plant receives.
