PLANT CELL AND HOW I MAKE MANY FORUMS INTO A BIOLOGY DEBAT

My presentation about plant cell has successfully confused many heads and turns many chat groups into Biology forums. And not to forget, I will mention my greatest honour to K13, that expands all discussion about plant cell into third grade materials.
So here is my presentation (completed and revision edition) about plant cell that ABSOLUTELY WILL HELP YOU:

The paradox and all bullshit in k13

This post is irrelevant to chemistry subject.

It's just a compilation of my unnecessary grumbles. It was 2 days ago when I tweeted some anger concerning teamwork and the flawed systematic of k13.
Then my dear friend, that is also my math tutor, favorited some of them. The tweets that got favorited by him are
"Discussion class sounds like bullshit to me" and "still clueless with this teamwork and what to do"
Well don't diminish my attitude score teacher, please. This is democracy and this is what I think about our new curriculum.
I know we are both trapped and you need to do many shits in score form. We both work hard in this new curriculum. We both sacrifice(well so hyperbolic). And the issue about making script makes this whole thing worse.
My friend seems Sick with the idea of this curriculum. Of course it sounds good but how could you think this concept works in Indonesia, Big people? That I can respect much more if you are more considerable.
I will point out some flaws in this system
1. It's 90%concept 10% 'i think our young people, the students can do it' and 0% effective.
Yet i think the cur-maker has no idea how to specify the system and in result, each teacher took initiative based on their own interpretation.
2. Attitude and knowledge that are nonsense. I don't think the grading of one's attitude is good. Yet Trouble teacher more ... like 'I am very attentive and aware to each children' and yes its not kindergarten. Its my opinion, i believe the attitude grading is ,instead develop students skill , Impede teacher to transfer the education. Coz man im so busy to see what the students deed!!
In other side, they can't give us sudden amazing and fictional score on it.
3. Can be exploited by bad teachie!
If u are a good teacher, you will work hard to grade everything but no no no. Some people can think this as a chance!
oh yeah lucky starrr!!
the concept of this k13 is students are active to explore the world(well its not some milk advertisement and shit).. This curriculum concept is misunderstood and misdeed by some teachers as we dont teach, you find out by yourself.
I think teacher, you have some limit tough.
I also heard the concept said that if a teacher graded your attitude(whether it disciple,active and oh!this hypocrite grading :politeness) bad, you can Charge them about it! So teacher should note when did you do this disgrace conduct!(it's troublesome and get you in debate of you really demand them)
Oh yeah i heard a case about the exploitation of attitude grade from a Stingy teacher.
Well im not saying you, the teacher is the Accused here, but please confront my dear friend about her misdeed
So my friends knowledge score was increasing but for her surprise, her attitude grade is decreasing! So the approximate value of her grade is constant. Well its a bit suck if the teacher is seriously stingy!

If you scrolled down students tweets, or read their Answers about k13 in ask fm. Well i cant guarantee anyone that is cheer about the new system.
And satan please dont give more shits in this k 13 such as making script and all

Pointing Out My Past Confusion on Subtle Difference of Mol, Molarity and Molality

It was a cloudy explaination when I first joined chem club in my school. My senior gave me a note about three of them (And yet I still haven't googled why should they make these three words sounds a bit different) and reluctantly gave us a worksheet to do. In my freshman, stoichiometry is the last subject to learn in first semester. I was not used to use distributive equation in my high school as the problems were always straight forward and didn't require much logic. (It means one kind of equation is needed). But when I entered highschool, I realized how my brain was not used in many years before.
I was so impressed when my senior solved the problems(that is really a standard) and decided to continue learning in this club.
But now I'm surprised about my way of thinking in the past. Moreover, the stoichiometry sheet was such a shit. So sorry but I found more mathematic and conceptual based that is so far complex than my past works. Well, that's a brief background about my stoichiometry startover.
I want to comment a bit about a problem that I found in my chem club test.

An x(assume this is a digit) Molar solution of XXX(assume this a compound) is 5 L. Determine the mass of XXX?*given the MW*

When I did the work, I wasn't prepared and very nervous. I thought the molar in this problem is mol. But note it the mol is a scale that denoted by n and Molar is concetration. denoted by M.
I filled the sheet by assuming molarity is a mol. All of the sudden I rethink about what is the 5 L doing here? Then I recalled some moments.
"Mol is a scale that reflect 6.02x10^23 particles and Molarity is mol per litre. It shows the concetration of an element or compound in a solution"
So I erased my previous answer and corrected it.
Then I realized and keep it in my the difference here. After that, I found another problems in colligative and it does contain a scale called molality.
My senior told me that Molarity and molality was different. But they didn't seem to explain the whole shit. So I found out myself when I began to learn colligative.
Well they both are concetration but according to the formula there is another difference here. When molar is n/v(volume), Molal is n/mass of the solvent. So the confusion is done here.
I hope someone is not confused about this little brats like me. and it was a bit dumb. But I praise myself by telling "YES THAT'S BECAUSE ACCELERATION! I ACCELERATE TO LEARN 3RD GRADE CHEMISTRY"
However, colligative and mol and Molar still nothing to organic in term of difficulty. So yezzz I'm still trying in organic!

Have A good day!
