Someone asked the question: Is there a difference in the growth of flowers if the water temperature is cold or if it is warm? Design an experiment which follows the steps in the scientific process. The Question: Will flowers grow better in cold water or warm water? The Hypothesis - The temperature of water will make a difference in the growth of flowers. You will have 3 groups of seeds to use:

Group #1 (control group) uses the regular temperature water;

Group #2 uses cooler water;

Group #3 uses warmer water.

what would the 3 variables be in this experiment?
