method
The five agar plates were layed out
A cotton bud was then used to swap the table
The cotton bud was then rubbed on to one of the agar plates and placed to incubate
Four different section of the table surface was then wiped then wipe town four different sections of the table using your four variable water soap antibacterial spray and antibacterial wipe
Then the four different cotton bubs were used to wipe swap those four surfaces
The cotton bubs were then rub on the other four agar plates and were left to incubate
After a week’s time the agar plates were taken out of incubating
The result from the four agar plates were than compared to the one agar plate
I will be incubating the agar plates for a week then i will observe the results
One of these agar plates will be used as the comparison the other four will be swapped after the surface has been wiped down
I hypothesised that the antibacterial wipes will have a lower transmission producing a much better result, compared to the other 3 substances which I will be testing in my experiment.
The independent variable will be the 4 different t solution which will be used to clean the Bactria from the surface this Is the variable which will change throughout the experiment the dependent variable will be the table which will be used to source the Bactria this can alter the experiment depending on which part of the table will be tested
Reserch
Most antiseptics and disinfectants kill bacteria immediately by causing the bacterial cell to explode or are known as bacterial conjugation by consuming bacterial resources by preventing the multiplication of bacteria.
Bacteria usually attaches to surfaces that initially resist the attachment of cells
The dependent variable was the bacterial growth which was used to source the Bactria this could have altered the experiment depending on which part of the table was tested
The controlled variable which played a huge role in my experiment which was the comparison agar plate not inoculated
The independent variables were the 4 different solutions , this is the variable which was changed throughout the experiment
