10oc Temperature Experiment

The experiment was somewhat successful in supporting the hypothesis. However, as a result of large inaccuracies and inconsistencies, it was difficult to make clear conclusions on the overall investigation of the experiment. The summary table portrays the errors and inaccuracies within the data. As evident in the table, the 10oC temperature is very accurate as the range was 0, resulting in an error percentage of 0%. However, the 35oC temperature had a no clear skew of results as indicated through the range, 14 and the error percentage, 161.47%, suggesting that the trials at this temperature were not very accurate as they were largely inconsistent. The 50oC also proved to have inaccuracies, however, not as significant as the previous temperature,
Whilst the experiment design was valid, improvements to the design could have improved the accuracy of the experiment. The recording of the temperatures using Vernier temperature probes would have allowed for a more simultaneous method and avoid error of parallax, as the thermometers relied upon the ability of the human eye to decipher the temperature, additionally the temperature was not measured from eye level, but rather standing height. This means that the varying trials of the one temperature may have had varying temperatures, creating error for obvious reasons. The validity of the experiment could also have been improved if the fermentation was recorded over a longer period of time, further research suggests that a minimum time of 45 minutes is ideal when waiting for yeast fermentation. A longer period of time may have allowed for the water in the beaker to heat or cool the flasks more effectively and create a more accurate response, especially as it was assumed that the temperature in the beaker would be the same temperature in the flask, however, this was not the case as the kinetic energy from the temperature of the water had to travel and it did not travel instantly. An experiment prior to this one could have been conducted to determine how long it takes for the flask temperature to become the same as the beaker temperature, however, as this was a consistent error across all trials it
The 10oC is the only reliable temperature with consistent results and a range of 0%. Both the 35oC and the 50oC are above the 10% range rising awareness to inaccuracy. The results of this experiment contained random error and some systematic error. Random error occurs as result of human inability to repeat an action in exactly the same matter. In the experiment error of parallax was particularly relevant as addressed earlier in regards to thermometers. Error of parallax was an issue associated with both the reading of the thermometers and the reading of the volume of water. Although water was measured from eye level into the flasks and beakers, error of parallax is still present even if fairly insignificant. Additionally the water was measured each time by different people allowing for different interpretations of what the exact volume should be in comparison to the necessary indications present on the beakers and flasks. Systematic error also played a small role in the inaccuracies within this experiment and links to random error. The thermometers used within this experiment were only accurate to 0.5 degrees Celsius, this lead to imprecision readings, which once again differed from person to person. Additionally the scales used only allowed readings to … To minimise random error the measuring and recording of measurements could be repeated at least twice. The
