Germination Lab

In my hypothesis I previously believed that the lower the lower the pH level the more seeds would germinate, due to the extra hydroxide. But more seeds actually germinated in the pHs closer to neutral. Some problems in the experiment was the towel drying out and the seeds no longer absorbing the pH, rewetting the towels with the solution could prevent this. Some experimenter errors that occurred is the seeds falling out of the towel which resulted in seeds germinating or not germinating. Also, air getting into the bags and drying out the towel faster could have been prevented by making sure the bag was closed. Lastly, the seeds did not get put in the bag exactly like the previous time which could have affected the germination. To improve this lab, measuring out the same amount of solution for each pH could have made it more accurate. To further this experiment we could have had another set of seeds in the same pH solutions but in the sun to see

Also, on the second day we observed that the seed in pH 5 was turning to a lighter color compared to the other seeds which stayed the same. Then again on day 5 pH 5 seedling stem was more white compared to the others which were more green. Lastly, in all of the different pHs at least 3 seeds germinated from each one.
The differences in all of the solutions was the pH, the lower the pH the hydroxide the solution had but the higher the pH was the closer it was to neutral. The results of our experiment varied from solution to solution, but the closer the pH was to neutral the longer the seedling was.
The control group in the lab were the seeds that were not soaked in any solution because the control group has nothing done to it, and the experimental group was the seeds in the
