Identifiying Variables
Use this link to an online exercise where you can pick out independent, dependent, and control variables in different situations. It’s a good way to reinforce what we’ve learned in the unit.
When you work through the practice, ask yourself:
“What is being changed?” → independent variable
“What is being measured or observed?” → dependent variable
“What is staying the same to keep it fair?” → control variables
Try to complete it before the test so you feel confident.
