After experimenting, we found the need to increase the rate of electricity produced by the bacteria, so we changed one factor: The Volume of Sodium Chloride solution.
Instead of pouring 200ml of NaCl solution, we used only 150ml of NaCl solution.
In Trial 2, we have obtained a significant change in results -- The rate of production was increased drastically.
Fig. 5 below shows the tabulated results:
Fig 5
As compared with Fig 4, the graph in Fig 6 has a faster, smoother increase, with less fluctuation than in the first trial:
Fig 6
Observations: With the decrease of the volume of the NaCl solution, the rate of the generation of electricity increases.
