My data supports my hypothesis because the water that is used as a growth solution, with an acidic concentration did not experience any growth. The average of the growth of all of the plants that were given vinegar and water, as a growth solution was zero cm. However, the average of the growth of all of the plants that were given just plain water, without any concentration of acid, received around 1.44 cm of growth, from the top of the soil in the pot of soil, to the top of the average height of the plant. The difference between the averages of the plants given vinegar, and the plants that were not given vinegar was 1.44 cm, the growth of the neutral-watered plants was drastically higher than that of the acidic-watered …show more content…
But, since all of the plants were treated with the same conditions, this might not have affected the reliability of my experiment. This may have an effect on my data, because the coriander plants may be more responsive to certain types of climate. For example, the coriander plants may grow better in hot conditions than in cold conditions. Placing the plants inside, created cold conditions, whereas placing the plants outside, created hot conditions. If I were to do this experiment again, I would have fixed this issue by placing all of my plants indoors/outdoors for the entirety of the experiment. Another issue that was pretty clear was that the amount of water that I watered each plant with was too much. Water dripped out from the bottom of the plants quite frequently. This could be a problem because an excess of water slows the growth of plants down. However, after conducting my experiment for many days, I decreased the amount of water that I used. If I conduct this experiment another time, I would only put as much water as needed for the plants, if water was dripping from the bottom of the plants I would reduce the amount of water that was used. Now that I understand how plants react to acid, I wonder how plants would react to being watered with basic
