I grouped the bacteria by, as I said, size and colour, but now I encounter quite some difficulty. The first of these is whether I should include analysis of the amount of mould in my report. I recorded the growth of mould in my data because it is very interesting, but it does not really fit my research question which is about bacteria. I think I can change my research to be about 'microbes' but antibacterial hand soap only claims to kill bacteria, so including mould in my research is rather a moot point.
Another difficulty is the fact that the pH of lime juice and lemon juice is the same - is it because they both contain citric acid? I think it is so, But now, what would be the chemistry aspect of my experiment? I think I will have to analyse the chemical components of the agents and find out what exactly kills or removes bacteria in them -- especially in limes and lemons. If it's really citric acid like I think, then this can be a chemical aspect of the experiment as well. (comparing the chemical properties of substances in removing bacteria).
And finally, I have no idea if we're supposed to hand in a draft of the report upon returning to school?
Here I am uploading links to the raw and more organized data.
