Event Log 5

Date: 15 feb 2022

Details: We also had a hard time using the refractiometre as the readings were a bit confusing so we had to retest multiple times. There were times where there was no reading too.

Event Log 6

Date: 16 Feb 2022

Details: We still had trouble trying to get the results on the refractiometre. We had readings that were very different for example for 1 rice, we had multiple very different readings.

Event Log 7

Date: 16 Feb 202

Details: We visited the lab staff for some help on the readings for the alcohol refractiometre. We managed to get the results for the rice afterwards.

Event Log 8

Date: 4 March 2022

Details: We tested for the accuracy of the alcohol refractiometre as Mr.Tan thought that the results were weird as compared to our hypothesis. We figured out that the refractiometre was accurate and our research for our hypothesis was the one that was wrong.

ANOMALIES

We had some readings in which we had very different. The alcohol content was very high and our team had to reconfirm the results by using 70% alcohol to see if the refractometer really can measure the correct readings. We managed to get accurate readings for the 70% alcohol readings. We figured out that we had to clean the alcohol refractometer thoroughly after use with distilled water so to get the most accurate results. This may have affected the results.
