Front

In an experiment, what does the independent variable affect?

Back

The independent variable causes changes in the dependent variable.

Front

What is a controlled variable?

Back

A controlled variable is a factor that is kept constant throughout an experiment.

Front

In the paper airplane experiment, what is the independent variable?

Back

The paper airplane design.

Front

In the grass growth experiment, what is the dependent variable?

Back

The height of the grown grass.

Front

What is the relationship between independent and dependent variables?

Back

Changes in the independent variable cause changes in the dependent variable.

Front

Why is it important to control variables in an experiment?

Back

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

Front

Give an example of a controlled variable in a plant growth experiment.

Back

The amount of water given to each plant.

Front

What happens if the independent variable is not changed in an experiment?

Back

If the independent variable is not changed, the experiment cannot determine its effect on the dependent variable.
