Whilst carrying out my investigation, in order to ensure fair testing, I used three pots that were the same in size. I also added the same amount of soil to each small pot as well as giving each pot containing seeds the exact amount of water each day. Each of the pots was kept in three separate containers which were all identical only the colour of the handles of each container being different. In two of the containers, a cell phone was placed, the same …show more content…
Thorough the investigation, the African daisy was always the first seed to grow in both containers A and C on about day 4. This was contradictory to my secondary research as in almost all of my sources, it was proved that plants that had classical music played to them grew faster, stronger and more healthy whereas in my investigation, the plants that had classical music did not grow at all even after the investigation had finished. The results from these seeds disproved my hypothesis as these seeds had classical music played to them each day and did not grow at all. There were no factors different in the handling of the three plants as they were each given the same amount of water each day and the amount of time that music was played to them was the same. Tampering was also removed from the seeds which show that I did not take care of one plant better than the other as I was not home when the music was played to the plants and that each day there was the same amount of water and sunlight given to the plants each …show more content…
This too contradicts the secondary research done as the secondary research shows that the plants with rock music played to them would not grow as strong and as healthy as the plants that had classical music. (Don Robertson The Plant Experiments, 2010) It did however prove that music does have an effect on plants as on day four of container C, the African daisies grew to 15mm whereas the plants in container A only grew to 5mm showing that rock does cause plants to grow at a much lower rate. After the investigation had finished, the pots were taken out of their containers and left on the same windowsill where they had been growing for the past 15 days. The African daisy that grew with the rock music started to wilt even after water had been given to it. This shows that the plant may have become dependent on the conditions inside the container in which it grew or yet the music that was played to it. In the case of the bean that grew alongside the African daisy, its germination and growth rate were both slower than that of the daisy. The bean plant had only started to grow on day 11 of the 15 days and remained under 5mm for the last four days of the investigation whereas the bean in container C started to grow on day 10 but its growth rate rocketed up to 60mm by the end of the 15 day investigation which shows that
