so i've conducted an experiment to determine whether or not water temperature affects plant growth, and if it does affect plant growth, which temperature is the most effective to increase the growth rate of a plant. it was predicted that the warmer the water, the more effective it will be, however if the water is too hot or too cold, the growth rate will decrease.
to do this, i tested 16 violas, categorised into 4 groups. each group received water with a different temperature. the first group received water measuring 45 degrees celsius, the second 35, the third 25 and the fourth 15. the plants were watered for a period of 14 days. after 14 days, the results were observed and recorded. it was found that the plants which received water measuring 35 degrees celsius had grown the most whilst the plants which received water measuring 15 degrees celsius had grown the least. it was then concluded that warmer water temperatures were the most effective and that very cold water temperatures had little effect.
