- Hi guys! - Hello!
How good was your science in secondary school?
Damn bad.
- Thought you supposed to be a nerd? - Oh ya.
Science bad?
I'm sorry ah...
My science was below average.
Eh I pure physics.
I also.
You thought I combined ah?
LMAO.
- I pure chem. - I also pure chem.
Oh.
I got B3.
- For both? - For both.
Same.
We like trying to compare who smarter but the same.
Wah.
Science is which subject?
Secondary school got science meh?
It's my worst subject.
My my my my chem my chem was not bad.
- Last time. - It's the worst.
What is your favourite science topic?
My favourite science is biology.
Err, in terms of the topics ah...
Ahh, wah I can't really recall
but I think I kind of enjoyed when we learnt
about the human body, the human anatomy.
Okay, I don't like physics. I love chemistry.
I actually failed at chemistry at first because
I didn't understand what the hell was it!?
But then when I understood it I was just like
oh...
She like bio practical.
- Err ya, the practical lesson. - Secondary school level...
Actually I only like
I only like those right
because I like to see how awkward the teacher need to teach.
But then they always try to keep a straight face.
- Guys, this is science ah... Reproductive system! - I have never done bio in my life.
Okay! So on this episode of Singaporeans Try
you will be trying 'O' Level Physics Questions!
- Yay... Nightmare... - (weird noises)
Wah. My brain a bit rot since then.
I think I'll do quite well.
- You'll do quite well? - I think my physics quite nice.
Quite nice? I think my physics quite good.
- Physique? Oh! - My physique.
Good ah your physique!
Okay! So upon 5, can you rate how well you think you'll do?
If you say X, I will be X + 1
I think I slightly better.
We will see!
WE WILL SEE!!!
Upon 5 ah?
- 0. - I would like to think I'm a 3.
I think a respectable 3.5
I think I would fail eh, 2.
- Okay lah... This question... - I think, I think I know.
Okay lah. This one is every day it always happens
- in the studio. - Ya, I know which chair!
Our chairs all spoil already!!!
Firstly, how did he get up there?
Ya, he is so short.
- That is physically impossible. - I think that is the real question.
How?!!
There's no steps, no nothing.
- And there's no parents to like prop him up. - To supervise...
Okay, our answer is
UNREALISTIC!
- D and C is like ehkkkk! - Because quite stable right? UNREALISTIC!
- D and C is like ehkkkk! - Because quite stable right?
- So close to the floor! - Correct!
A and B is the contender right?
So what is the difference between A and B?
The chair leg one narrow one wide!
Ahhh... So...
- Ya lah! Which one more stable? - Hor... Aye...
Jiu shi lor! (Ya lor.)
Okay ready?
Least stable ah!
Damn it!
A!
Jiu shi lor! (Ya lor.)
- Oh! - PD: C?
LEAST?!!!
Damn it! Damn it!
I still repeated the question for you!
LEAST stable ah.
No. This is why you should read the paper properly.
B looks like how Bolin would stand on the MRT
and C looks like how Sew would stand on the MRT.
Eh but this one is 'O' Level question ah?
PD: Ya.
Like easy ah?
Easy ah! (weird sounds)
What does moments mean?
Ah. Moments.
You hang out with people
and then those moments are...
So the rocks are like
- Which moments are that? - Those great moments in your life!
They seem happy! Omg, that makes a happy face!
Oh ya ya! No! The right one is happy!
Is the happy face.
Then the other one is the sad one.
What's moments about the pivot?
Okay, moments about the pivot is.
Moments must be equilibrium.
Weight must be in equilibrium.
So what can happen regardless of this?
Huh?
What you mean?
There's a moment lor.
I don't understand!
What's heavier?
A kilogramme of steel or a kilogramme of feathers?
The both weigh the same.
- Even though the feathers like take up more volume. - Take up more space.
- Ya. A kilerhgrahm of steel. - A kilerhgrahm.
Ok can.
A kilerhgrahm of steel.
Okay, so for example right.
Me and him we weigh the same.
But! Our volume is not the same!
- Some ice - Some ice
- Eh c'mon man! - Okay.
- Some - Some ice
Eh, c'mon man!
- Some, some ice cubes - Some ice cubes
So it's either A B C or D lah?
Wah, for the first time in SGTRY right
I'm confident eh.
K lah k lah, you damn smart lah!
But I think none of it is that.
- You see the graph ah. - Uh huh.
Eh! There's a flaw in the question eyy.
PD: I think you all are reading the graph wrongly.
1 is temperature.
1 is time.
Okay no no. Okay then. If that's the case.
Then I think I know already because...
Wait wait wait, I don't understand.
So your state got temperature change anot?
Think about it. Think about it.
Have.
Have ah?
Don't have.
Why you keep quiet?!!
AAHHHHHHHHHHH!!!
You write already anot?!
Wait I write but wait wait!
Wah later I too confident right, then wrong.
- It's like I know the - PD: Correct!
- I know the layman explanation but I don't know the scientific one. - Yes...
- C. - C.
Eh, your C upside down!
No, I write C then I write D Eh, your C upside down!
No, I write C then I write D
then I write C then I like
You know why it's not D?
Why?
Because freezer temperature is
lower than 0°C.
So far, a lot of the answers are C ah.
Maybe you should draw a vector diagram.
What vector diagram?!!
- What is resultant force? - How to write ah?
Isit?
- So you must overcome this 6N first - Ya.
and also plus 3 to that.
Ya. So that means the resultant should be
- 9N - 6 plus 3 equals to 9.
Correct ah? - 9N - 6 plus 3 equals to 9.
Correct ah?
It's quite simple right?
- Sorry lah my maths not good right. - Wait like!
PD: Ready? 3 2 1.
- C! - C!
This is a math question!
- Eh! It's C again! - Oi!
C is for cheers!
C is for correct!
You want 3 there right?
So you just get 11 minus 2 ah!
So that's the amount of force you need to push
to the left what.
I...
put my head down on the floor...
There's a saying mah, opposites attract.
Not only for magnets, for people
for personalities, so attract ah!
The magnetic field will move in one direction mah.
Ahh...
So you see A and B which one is one direction
- which one is not one direction - It's one direction ah?
Yes!
- One direction! - North to South.
Then what is A?
- A is just - Rubbish.
- Rubbish. - It's like ahhhh...
Let me trick you.
You know MRT?
- Uh huh. - Then the door close.
- Uh huh. - Then the people go in then they brsghghsh. Then they come out.
But what's the difference between A and B? They look the same.
No, you see the line!
- The bottom line is attracting. The top line is repelling. - Orh...
Where got make sense?
Think what! We primary school is it? So stupid?
- I know! As in... - Away from North and towards South.
- Always one direction. - Orh. Cannot be like that.
Cannot be suddenly South to North.
That means I think the answer is...
Is it A?
I'm going to draw a magnet first ah.
Oh my god, means wrong ah?
Magnetic field will be like that mah, correct?
- But the direction is always North to South. - Okay. Okay.
Right?
- So which one ah... Is not... Ahh!!! - Oh, aiyoh... Wrong...
Which one is not North to South?
3 2 1.
B
- B. - Yes, both of you are correct.
Adria, can explain why is it B?
So, umm...
Mr Lim has taught me that umm...
Umm, the the the...
- The pattern ah? - Magnetic field...
- This is a plane, normal mirror ah? - Ah, normal mirror...
Where is the image of the pin?
Pin...
Where is the image of the pin?
Oh! D is an option lah mangkuk(bowl in Malay)!
So it's A B C D!
- I thought D is like a point that they fixed already. - Oh.
- So we have to choose from A B C D. - Right right right right.
- So unclear the question. - Confusing sia.
- I put a thing here right. - Mmm.
I put my phone here right.
- Then it will be there lor. - Ahh...
C!
So you look at yourself in the mirror, ahh!
- Why why why? - Because it re...
fffff....
flex?
- Yes. - And...
Fracts.
I think it's behind right is because
The mirror still accounts for this distance.
Oh, but the mirror is long all the way lah?
- The mirror doesn't end where the shaded area ends! - Ya.
No but actually doesn't matter even where the shaded area ends.
I feel like I use logic in this.
- It's true! You can visualise mah! Dui bu dui (correct a not)? - You just think about it. You just look at the mirror.
It's somewhat reflecting.
Then
like that lor.
- Yes. - This one no need physics also know.
3 2 1.
C!
Both of you are correct!
So you know when you look in the mirror right?
Then you can see like you know those
- mirror mirror kind? - Mm mm mm.
Then in the lift. Then you alone.
- Then you can see so many of you like - Eh! So scary!
Don't say that!
- Orh! - Got this question?!
Huh?
There's a question like this? We learn this?!
So light...
- consists of the 7 colours what. - White light...
Correct.
- So when it goes through a prism - Correct.
Somehow, it gets split up into all the different
- individual colours - Yes.
- Then it will look like a consistent rainbow. - Ya, something like a rainbow lah.
Last time my secondary school teacher teach me ROYGBIV.
And they also teach me an easier way to remember.
Richard Of York Gained Battle In Venice.
Then actually this question right
is it a bit like a trick question?
No, it's not.
No, as in like...
You will choose infra-red meh?
Absolutely not.
Han nah!
As in, huh???
- What? Girl?!! - No no!
- GIRL WHAT YOU SAYING GIRL. - Noooo...
What's the rainbow format?
I'm not going to tell you.
Red...
Or is it
Blue green yellow!
What kind of song is that?
What school you go to? I don't know sia.
Orange! Red!
Pink!
This thing I learnt in design school.
No, so got 3 primary colours right?
That means the in betweens are just like the
- combinations so for example - Orange.
- That kind of thing. - Oh wait.
I was going to write red-yellow but yes it's orange.
You went to which design school again?
3 2 1.
- C is the answer! - Bring it!
C!
C.
Okay yes!
Do you not remember the colours of the rainbow?
That's why I write!
So yours is mental sums.
Mine is working.
Sometimes right
you get more marks for working
because they know what you are thinking of.
It's MCQ!
You colour the circle! It's MCQ!
You colour the circle!
They can't see your working!!!
How do you all feel about your results?
- Wah! Disappointed in myself eh. - Hmm!
- That was fun! - I'm disappointed, I'm disappointed.
I realised that
it's 'O' Level subjects la so it's err
it's what 16 year olds are doing.
Not a very big accomplishment.
Okay, so which question was the hardest to answer?
For me right, I think all the questions were okay lah. It's just that
I cannot remember the definitions.
I think the hardest question for me was
How did the boy get onto the chair?
I scrape my answer!
That is the hardest!
I think everything is okay.
It's all about the English.
You have to read the questions man.
- Read it properly. - Really have to read properly.
Don't be like a Rainier.
- Overconfident. - Least!
Overconfident until like I just nevermind ah!
Can one lah.
How has your understanding in physics changed since the start of the episode?
It was actually damn long ago since we took physics
or touched anything related to it.
So, when we managed to answer the questions
and still have like basic generic knowledge
about some concepts and terms
it's quite a nice feeling lah.
I must say some of them are common sense.
Because if you think about it in real life
Even at the playground
- Ya! Correct! - then there's like see-saw all that what right.
Correct!
Sometimes, sometimes, if you use a bit of
logic, I think you can?
Physics is not something that you
should memorise to understand.
So like for those who are taking 'O' Levels
understand the theory behind physics.
Don't just memorise and then like
think that you can memorise your way through.
Ya, it's not going to work lah!
