Variables

Variables: 

o Independent Variables (IV):These are the variables of which you have control, the items you are changing or manipulating from your materials list. 

o Dependent Variables (DV): These are the variables that are to occur as aresult of your project. Examples: bubbling  mixture, balloons blow up, salt disappears, model works correctly, etc. This is NOT a summary of your results. These are NOT found in your materials list. 

o Constant Variables (CV): These are the variables that remained the same from experiment to experiment. These are found in your materials list. 

o Control Variables: This is the experiment that has no manipulation done to it all. For example, the plant that does NOT receive any fertilizer (if you are testing for fertilizer), the ball that is NOT bounced (if you are testing the heights of a ball bounced on different surfaces), etc.
