Problem Statement

Problem: 


What is the problem/question you are trying to answer? You need to label 
the IV, DV and CV in the problem statement. 

Ex. Which fertilizer (IV) will 
produce the tallest plant (DV) in a pot of 7 cups of peat moss (CV)? 

Independent Variable - IV - 
The item being changed in each experiment, or different condition being tried 

ex. testing different fertilizers, amount of sun light, different seeds to test growth


Dependent Variable - DV - 
The expected outcome

ex. tallest plant, furthest distance, fastest result


Constant Variable - CV - 
All of the conditions that are remaining the same in all experiments, the items NOT  being changed, the items that stay the same


Control Variable
The control experiment that has NO changes whatsoever

ex. the plant that has NO fertilizer, for instance
