Front

What is an independent variable?

Back

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

What is a dependent variable?

Back

A dependent variable is the variable that is measured and affected in an experiment. It responds to changes in the independent variable.

In a scientific experiment, which variable is plotted on the X-axis?

Back

The independent variable is plotted on the X-axis.

In a scientific experiment, which variable is plotted on the Y-axis?

Back

The dependent variable is plotted on the Y-axis.

Front

What is the purpose of controlling variables in an experiment?

Back

Controlling variables ensures that the experiment tests only the effect of the independent variable on the dependent variable.

Front

How does temperature affect cricket chirping?

Back

In this experiment, temperature is the independent variable, and the number of chirps is the dependent variable.

What is an example of an independent variable in a study about plant growth?

Back

The amount of sunlight each plant receives is an independent variable.

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

Back

The height of the plants is a dependent variable.

Front

If a researcher is testing how different fertilizers affect plant growth, what is the independent variable?

Back

The type of fertilizer used is the independent variable.

If a researcher is testing how different fertilizers affect plant growth, what is the dependent variable?

Back

The growth of the plants (measured in height or biomass) is the dependent variable.
