Discussion
The T-test from the class supported our hypothesis by showing that Sulfuric Acid diffused significantly faster than phenol red at both temperatures (Fig 1). We can say that our hypothesis for experiment one is supported under certain conditions. The rest of the data in our charts supports our hypothesis as well. However it is not well supported. The rest of the test results were inconsistent with the null hypothesis. The error bars from the class data show a possible cause of insignificant data. The t test results for molecule size and temperature has only one significant value so we cannot compare the data to know for sure if the results from the class can be supported. There were not enough replicates to prove our hypothesis for experiment two. It is not strong evidence because there was only two replicates of each …show more content…
The main source of error in this experiment was the incubator. To increase of the likelihood of this error not occurring again the class could check the incubators before to make sure they are function correctly or use a different method of comparing different temperatures such as one at classroom temperature and one in a refrigerator.
After the conclusion of the experiments in class it was concluded that that all trails conducted of the agar dishes were different. This did not support the second proposed hypothesis because each trail had different diffusion rates. Meaning that the smaller molecules diffused faster than the larger ones. In the agar dishes with the Phenol Red, the agar dishes at 56O C had diffused quicker than those at 20OC however the dishes with the Sulfuric Acid showed that the 20OC H2SO4 diffused quicker than those in 56O C; this should be the opposite case for the H2SO4 because heat causes the molecules to diffuse faster.
