Why is it important to control variables in experiments?

Controlling variables is crucial because it helps ensure that the results of an experiment are due to the independent variable, not other factors.

Can you give me an example of a controlled variable?

Sure! In a plant growth experiment, if you change the amount of sunlight, you should keep the soil type and water amount constant.

What happens if we don't control variables?

If variables aren't controlled, it can lead to inaccurate results, making it difficult to determine the true effect of the independent variable.

How do scientists decide which variables to control?

Scientists typically identify variables that could influence the outcome and choose to control those that are not the focus of the study.

Are there any exceptions to controlling variables?

Yes, in exploratory research, some variables may be left uncontrolled to observe potential relationships or effects.
