A Constant Variable is everything that is intentionally kept the same in an experiment to ensure that the results are valid.

Front

What is an example of a Scientific Question?

Back

An example of a Scientific Question is 'What is the effect of amount of sunlight on plant growth?'

Front

Why is it important to have Constant Variables in an experiment?

Back

Constant Variables are important because they ensure that the experiment is fair and that the results are due to the Independent Variable.

Front

What is the role of the Independent Variable in an experiment?

Back

The role of the Independent Variable is to be changed or manipulated to observe its effect on the Dependent Variable.
