Preparing for the incubating germ
Feb 5, 2020 - February 18, 2020
Mr. Kinthern told me to incubate germs to test my sanitizers so I bought 2 dishes to compare, agar. Saw many youtubes to prepare for it. First, I bought this incubating set from Korea, but I heard how how to do it easily to the another friend who did this, so my mum refunded it and prepared it. I bought agar and plain dish at the store which is in front of our house.
Feb 7 2020 - Feb 10 2020
I have to ripen natural detergent which is made of orange peels and alcohol in the fridge.
Feb 11 2020 - Feb 18 2020
I putted gelatin in the plate. Prepare 2 to compare and rub one with a dirty hand and rub another one with the hand that is cleaned with sanitizer. When bacteria has grown enough, compare it.
To make the house for the germ's house, put agar and water and boil it. You can put sugar. Make two compares and test.
Feb 15 2020 - February 21, 2020
Mr. Kinthern suggests another test-with different amounts of alcohol so I made it with 30%, 50%, and 90%. I made dirty hands as well, and added a hand which only used water to wash to compare with average.
However, it didn't seem to grow a lot, so I made another one at monday. And I had to buy extra alcohol, and a lot of bottles and clear dishes.
Feb 20 2020 - February 26, 2020
Mr. Khinthern told me that it was not the way how to test it. I rubbed hands at agar medium right after I made it, but Mr. Khin thern wants me to grow 4 equal bacterias first, and put sanitizers inside after it's fully grown and find out that has it removed.
