I finally finished my report!!! it is a really great and rather difficult experience to put all my thoughts and results down, as there are so much to write about!! but at last, it is done and I have said all that I want to.
Here are the links to the online files mentioned in my Appendix:

To the dear teachers marking this blog and the report: I know I've put up links to my data in the previous posts, but these are the refined ones, so they would be slightly different and more organised.
My blog has been a faithful documentation of the thought processes in planning the experiment, and notes taken to refine the report, etc etc. Thank you blog!

Notes about my experiment and report
We went through the rubrics today. Things to note:
1. Present representative photographs in appendix, and add a link in the hardcopy to the online scrapbook to see full details of photos.
2. MUST paraphrase the lit review presented in the report. Would there be a section in template to include lit review?
3. Refer to lit review in the design of the experiment
4. For results, use 2 decimal places of accuracy whenever unsure. Follow strictly the calculation of levels of precision as learnt in physics.
5. Methodology MUST be reproducible - ask friend to try out based on given instructions.
6. Point out control variables that cannot be controlled.
7. Remember to vary ONLY ONE variable.
8. Data collection: is all the data collected necessary? Are the data collected enough for a good graph/analysis?
9. Presentation of data - in tables, with appropriate and SPECIFIC units and precision.
10. plot a graph for data analysis, in my case the rate of bacteria growth as graphs.
11. Use line graphs for rates and bar graphs for numbers.
12. refer back to literature review and observations in conclusion.
13. Limitations - things that you really cannot control about the experiment.
14. Extension - VERY IMPORTANT. further questions from your experiment. Crucial in a scientific investigation.
15. Provide plenty of evidence - hard data and photos - in the blog.
16. List out materials specifically.
17. Reflect on how to make the experiment better with more time/how to make it bigger.

Review and Revise
After meeting Ms Tan, I need to do another batch of bacteria culture as I did not have negative control (an agar plate that has absolutely nothing done to it, to see the sterility of the agar plates), so in this new batch there will be a 7th plate, the negative control. I also need another batch to consolidate the results I have which are right now rather messy. If i have another set of results, I can analyse it more and perhaps identify the outliers more easily.
Another matter I am considering is the method of presenting my data. After all, I really have a lot of data. Right now I'm presenting in a table and maybe graphs the average amount of each type of bacteria on agar inoculated by each agent ON THE 3RD DAY, and on the 3rd day only. I have not yet decided whether to use the data of Days 1 and 2 anywhere. I think I need to decide because if not, I can save work and time by not counting the bacteria on Days 1 and 2 for my 4th batch.
I'm thinking to not waste any data, and present data about the rate with which DIFFERENT TYPES OF BACTERIA appear on plates inoculated with DIFFERENT AGENTS. to this, i can plot a combined graph of each type of bacteria, x-axis the number of days, y-axis the amount of bacteria, different lines representing different agents. Or I can plot combined graphs of each type of agent, with the same axes, the different lines representing the different types of bacteria. It all seems very very complicated.
So should I present the rate at which bacteria appear? It promises to be interesting, but is it relevant to my research question which is about the amount of bacteria removed? Does the rate at which bacteria colonies grow have any significance on the amount of bacteria inoculated onto the plate?
Or - another idea - maybe i can just use the data from Day 1, immediately after inoculation and on 3rd day.
Ms Tan also advise me to:
1, use pi to calculate area
2, use imageJ?
3, think about whether using different fingers affect the amount of bacteria
4, THE OPAQUE WHITE 'MOULD' IS ACTUALLY BACTERIA.
5, use the great photos i have so painstakingly taken!! yay, should i attached ALL of them as appendix?
By the way, is there a limit for appendix pages?
