Week 5 : Discussion

Throughout my experiment in which my aim was to determine whether the temperature of the water affects the solubility of the Panadol tablet , the results that i obtained showed obvious patterns which i would later notice. Firstly when comparing my results acquired from my three trials of my experiment it was evident that the results were fairly all similar . In doing so i was sure that i was on the right track as the numbers were not far off each other . I was glad that i had repeated my experiment to test for reliability and validity because if i didn't i wouldn't know if my results were way off or if they were correct. To execute this experiment in the correct manner i had to determine which water condition would make the tablet dissolve the fastest in. Although i originally thought this concept would be easy enough to figure out , as i progressed with my investigation i found that there were some simple implications.  In my trials each reaction time stayed consistent meaning that my results did not fluctuate. When the different water conditions were tested it was found that the Panadol rapid soluble tablet dissolved the fastest when placed in the hot ( boiling water ) hence that was why i found that the tablet dissolved the slowest in the cold
( refrigerated water )  and of course that left for the normal ( room temperature ) water to be in between.

Results in my experiment was obtained through the collection of raw data , which i would then record into  three tables . By merging my results conducted from my three trials i was able to a procure an average of the reaction time . By absorbing this data i was able to get an understanding of how the numbers were when averaged hence gaining a better concept of this experiment. Since i had recorded the time it took for the tablet to dissolve i was able to receive an accurate comparison of the results . It was evident to me that my hypothesis had been right from the beginning , consequently this meant that i was able to successfully accept my hypothesis just as i thought . By incorporating graphs as such i was able to show the relationship that formed when my results were recorded, thus enhancing my studies which ultimately backed up my whole entire hypothesis.  My research showed to be helpful as i gained further knowledge about this topic and how the tablet would dissolve depending on the temperature. Through more studies and research i found out that the bicarbonate ions from the Panadol Rapid Soluble tablet would have to come in contact with the hydrogen ions in order to form carbon dioxide and water which was the finalising result of the chemical reaction that took place . Needless to say the chemical reaction would only take place if the hydrogen and bicarbonate ions collided at right angles , this was immensely crucial.


Discussing the matter of the reliability and validity that took place within this experiment it can conclude that it would be a very reliably source as i have repeated this experiment. To ensure that reliability and Validity took place within my experiment i had to repeat my experiment two times , so that meant that in total i had done my experiment three times. This gave me a better conscious when working with the numbers as i knew i could rely on my two other trials for my experiment to visualise my end results. The validity that i had sought to include circles my whole entire experimental concept ultimately this determined whether my results obtained met all the requirements of the scientific research method.To ensure validity a constants or control had to be established . It was shown that from the start internal validity and reliability were the core to any experimental design this was why i found it remarkably important to include both reliability and validity throughout my whole experiment whilst keeping it consistent.

Despite the fact that my experiment was a complete success , there are still many factors of which i could have improved to make my overall experiment better. Firstly i could have completed more trials for my experiment , this would have definitely increased my reliability and validity of my experiment. Although my results were not scattered , in fact the results were merely all close there is another factor that may have contributed to my experiment not being a hundred percent accurate. After my experiment i've realised that i should have measure the temperature of the water conditions with a thermometer , this would have definitely boosted my accuracy throughout my entire experiment. By measuring the temperature of the normal ,cold and hot water i would have been able to give myself a higher chance of reliability hence making my investigation better. These few factors that could have been improved shoe how far i have come as i have realised the things it will take me next time to make an even better , brighter and more successful experiment. I will definitely keep all these factors in mind for next time !

To draw to a close , it was clearly evident that there were apparent patterns throughout my trials that i had conducted , these patterns would soon be relevant to my whole entire investigation as it showed me where certain trends were forming in relation to my project. I am also glad that i had completed all of my research before attempting the experiment as that gave me more confidence as i knew what i was doing therefore i could execute my experiment in a better manner thus obtaining the successful results that i received. In the mere future i will be able to take on board all the mistakes and all the positives that i have  done , so that my future experiments can be much better !
