Variables in an Experiment

Independent Variable- variable that we are testing; we change it, manipulate it to see what happens.

Usually after the word "different"

Dependent Variable- variable that we using to measure the independent variable. Could be weighing, counting, checking temperature, measuring the size, etc.

Constant- Also known as the standardizing variable, it's the variables that has to stay the SAME through out the experiment
