You will not be changing these but you will be keeping track of them as they will often times indicate the results you are looking for. o Independent Variables – These are the variables that YOU will change in your experiment.

      Scientists collect data on the dependent variable to see how it responds to the change made to the independent variable. The new value of the dependent variable is caused by and depends on the value of the independent variable. For example, if you open a faucet part way (the independent variable), the quantity of water flowing (dependent ...

      An experiment can have three kinds of variables: independent, dependent, and controlled. The independent variable is the variable that is purposely changed. The dependent variable is the variable that is observed. Measuring changes in the dependent variable should answer the question the experiment was designed to investigate.
