Some more research~

How shameful of me to do it so late. amirite? Ah well, I tend to work well under pressure apparently so here we go!
For my introduction, as I mentioned before, I wanted to briefly describe what milk was... I seriously don't know how to describe it myself, besides saying that its a white liquid that tastes nice. LOL.
The thing that came up when I typed it in in Google was "a white nutritious liquid secreted by mammals and used as food by human beings" and I was like, obviously. (wordnetweb.princeton.edu/perl/webwn)
Anyway, then I'd talk about more stuff on milk and expand onto what casein is and why the reaction happens.
Then stuff about other experiments and afterwards, supposedly the aim and hypothesis should be subtly put in.

I need to learn how to reference. Like really badly. Did we get taught in class? I can't remember if we did. Oh well. Time for Google. -cracks knuckles-

Oh and seeing as I am really tired today, I'm doing my experiment on Monday (public holiday FTW) or tomorrow. I'm such a bad person. I'll regret it later though.

Another Delay...

I seem like such a slack student T_____T

But it's seriously not my fault~ Remember how I said I'd do my experiment on Tuesday? Well, I got sick on Monday night with the aforementioned conditions that my siblings experienced so I couldn't do it. I also missed out on the cover sheet omg fml so hard for the report. So I need to see Ms Zhang. ASAP.
Or maybe I'll just photocopy someone elses. Ms Z, you don't need to sign off my name or something when you give it to me do you...?

ANYWAY, I'm going to do my experiment on Saturday now[after I finish my coaching tests ;-;].

Risk Assessment -gulp-

So, a little birdy told me that we had to write up a risk assessment. I can't really think of anything that is too fdangerous about my experiment. Eating/drinking milk, vinegar and casein isn't really that bad for you (I think) it's just that it might not taste too nice LOL. Which reminds me of that year 8 or 9 experiment where we had to taste stuff like vinegar on our tongues and I was the test subject because Emilyn an Jamie bullied me into it. -.-''

Anyway, I know that boiling milk is potentially dangerous as well as pouring it into a bowl. Yes, very dangerous

Identify: boiling milk, stove
Assess: is able to cause burns or scalding to skin
Control: do not place hands near stove, carefully pour milk into bowl
Disposal: milk is able to be poured down sink

SUPER IMPROVED METHOD

Equipment

·        1x spoon

·        1x large strip of cloth

·        1x saucepan

·        1x thermometer

·        1x measuring cup

·        1x ceramic bowl

·        350mL of vinegar

·        190mL of full cream milk

Procedure

·        Place the strip of cloth over the sink and the ceramic bowl on the bench.

·        Pour 20mL of vinegar into the measuring cup.

·        Heat the 200mL of milk in the saucepan to a temperature of 50°C.

·        Pour the heated milk into the ceramic bowl.

·        Add the vinegar to the milk in the bowl.

·        Stir the mixture with a spoon for one minute.

·        Pour the contents of the bowl carefully onto the cloth.
-Grab the corners of the cloth and tie the cloth around the tap so that the liquid is able to drain at the bottom.
-Wait for 5 minutes for the liquid to drain.

·        Remove the cloth from the tap.
-Gather the solids in the cloth and mould into a relatively round ball.

·        Place in the sun to dry for one day.

·        Tabulate information on the resultant substance including: weight, hardness, colour, flexibility and smell.

·        Repeat experiment replacing 20mL of vinegar with 0mL, 50mL and 100mL of vinegar.

Not doing my experiment yet...

Why? Because my brother and sister are currently diarrhea-ing and vomiting all over our house and setting up a smelly experiment in the kitchen wouldn't exactly be helpful to my parents, especially as they went to the hospital last night at 12:30 and left me alone at home. So, for now I'm just going to have to write up my report and do the experiment later. Maybe Tuesday would be a good day... or Wednesday. I can't believe how soon the SRP is due ;-;

Ok, so for the method all I have to do is change my blog's method to passive past tense in paragraph form. Which reminds me that I have to change the method again so that I can use the cloth as a strainer rather than the normal strainers. So this will be the third time writing my method out. Joy.

Need to Start Writing my SRP soon....

I'm seriously so screwed. But hopefully I won't leave it until the last minute. I've decided that I'll redo my experiment on the weekend or on Friday night.
Now, however I need to write the whole report up!

Firstly there's the abstract which is a brief summary of what I did.Which shouldn't be too hard seeing as I didn't have much to start off with anyway
Then I should write my introduction... I'll put it in dot point here and write it up in full for my report. :D

Explain what casein is.
Explain why milk reacts this way when vinegar is added to it?
Say what uses casein has (i.e making mishti, cottage cheese, yoghurt etc)

And the rest I will think about and add later...

My Awesome Revelation

Long time no post man. LOL.
Anyway, remember how I found out that my experiment is actually used for making curry stuff? Well, my aunty happens to do this experiment practically every week. Why? Because she sells mishti. Mwahahaha. So I asked her about my experiment and I found out that...

Too much vinegar = the end product is too hard and smells really bad but there is also more
Too little vinegar = end product doesn't form too well, smell isn't as bad but not that much is made

Also, when I told her how much milk I used, she told me that you could get less than a hand full of casein. Well, now I know how much I lost down the drain. And why she has humongous pots in her house.
Furthermore, I delved into the deepest pits of my memory until I remembered my parents making mishti, and I really wanted to help. Anyway, the main point is that when they filtered the casein, they used a cloth to drain out all of the water, so that the water could completely come out and no casein would be lost. Now I know why a normal strainer didn't work. x.x

So... all that's left is for me to do my experiment again? Oh wait, I have to write up my method, AGAIN. Waaaaaah~

----- I just realised, do I list my aunty in my a references, bibliography or acknowledgments? I'm leaning towards acknowledgment...
