Conclusion
The purpose of the experiment is to find out which household cleaners between Clorox Bleach, Windex, and 409 Cleaner is the most effective against the bacterium E.coli. The initial hypothesis was that Clorox Bleach would be the most effective in killing E.coli. However, Clorox Bleach is known to be more harmful and so the hypothesis for the safer alternative was 409 cleaner. Supporting the claim, the data suggested that the more efficient household cleaner was 409 cleaner instead of Windex.
Figure one exemplifies that Clorox Bleach had the most amount of disinfection as trial one had 13mm, trial 2 had 11mm, trial 3 had 18mm, and trial 4 had 19mm. Following Clorox Bleach, 409 had 5mm of disinfection in trial one and three and there…show more content… Another example is that the petri dishes were moved from their initial position in which they were once placed. Sources of error that could have affected the results are the spacing between the disks. Some disks were closer and others farther, which could have affected the amount of disinfection. Another source of error could have been when conducting the experiment, the distance the cleaning products were sprayed onto each disk. The distance it was sprayed was an approximate measure of three inches away from the disk; it was not measured by ruler for an exact measurement. was a. This could have affected the quantity of how much of the cleaning agent was sprayed onto the disk, which would have affected the results. Further questions that arise from this experiment include, what other cleaning products may be more effective? What can be the hazards of these cleaning products and what effects could they lead to. Are there cheaper alternatives that may be better disinfectant? How much of general bacteria is killed by these cleaner? A follow up experiment that could be done to expand results could just be more trials to further test the household cleaner disinfectant potency. The more trials would ensure more accurate
