CER and Scientific Method Review

What is an independent variable?

• What a scientist changes in an experiment to test their hypothesis

• What scientist measure to see if it responded to a change

• What happens when you do an experiment

• What you keep the same throughout all experimental groups

Why do we want to test one variable at a time?

• Because it is hard to setup a data table with more
• To know what is causing the changes. This helps us understand cause and effect.
• It is what has always been done

What is a constant/control in an experiment?

• Things that do not change in a experiment. It's the variable that stays the same. You can have many variables stay the same.

• It's the variables that the scientist changes in the experiment

• It's the variables that are being measured in an experiment
