3. Results

After carrying out the steps in 2.5 Data Analysis, we filled in this table with all the data gathered. Using these data, we then plotted the three graphs below: a line graph for the change in mass of the wire mesh and copper rod; a bar graph to compare the increase and decrease in mass of the wire mesh and copper rod respectively; and a bar graph to compare the increase and decrease in mass of the wire mesh and copper rod per day respectively. However, due to certain constraints (e.g. being unable to enter the lab on some days), we were only able to gather data on certain days when we had Science lessons. We overcame this issue through finding the increase and decrease in mass of the wire mesh and copper rod per day respectively, but it was still fluctuating due to certain errors (e.g. certain components stopped working on certain days, like the crocodile clips coming off or the wire burning). However, the overall trend for the mass of the wire mesh and the copper rod is an increase and decrease respectively, showing that our setup works.

This figure shows the changes regarding the actual weight of both the wire mesh (Cathode) and the copper rod (Anode).

This figure shows the increase and decrease compared to their previous weight of the wire mesh (Cathode) and the copper rod (Anode).

This figure shows the per day between the wire mesh (Cathode) and the copper rod (Anode).
