Front

Why is it important to identify independent and dependent variables in an experiment?

Back

Identifying these variables helps to understand the relationship between them and to determine how changes in one affect the other.

Front

What is the purpose of a control variable in an experiment?

Back

Front

How can changing the independent variable affect the dependent variable?

Back

Changing the independent variable can lead to different outcomes in the dependent variable, allowing researchers to observe and measure these effects.
