Yesterday's Bio Practical
It was the third bio practical I had. We tested several food substances to find out if it contained starch, reducing sugar, protein and lipids. For the starch, you should know, just add iodine. For the reducing sugar, we added Benedict's solution and for lipids, we had to add 5ml of sodium hydroxide and 5 drops of ClHO4. Warning!!! The 10% sodium hydroxide will dissolve you!!! For proteins, we added distilled water and something else.
I remembered we had to insert the test-tube into a 80 degree celcius water bath. There was once my friend's hand accidentally touched the sodium hydroxide. He said it was scorching hot. That was just 10%, imagine pure 100% sodium hydroxide. We sometimes inadvertently add too much chemicals and cause a huge explosion. Just kidding, nothing actually happened.
Practicals are always fun and enjoyable. I am looking forward to the next practical.

Illusion - Dancing Girl
If you see this lady turning in clockwise direction, you are using your right brain.
If you see it the anti-clockwise direction, you are using left brain.
THIS IS NOT A JOKE. BOTH DIRECTIONS CAN BE SEEN.

Chess Competition
I participated in the 60th Nationals Individual Chess Championship held at Teck Ghee C C two days ago. I won on the first round, lost in the second, won in the third, lost in the forth and fifth, and won the rest. There were a total of 8 games. I won 5 of them . Too bad I still could not get any prize. One of my friends (my classmate, Jia Hong) took part in the girls category. She also got 5 points, but I think she was one of the top 20. This is so unfair, they should mix the girls and boys category. The girls category has less competitors (42, compared to the boys with 179), and is easier to win.Tuesday, 11 March 2008

PBC labs
PBC stands for physics, biology and chemistry. Let me describe what we have done in the PBC labs.
For physics, we did some practical exercises. We used some things like vernier callipers and micrometer screw gauge. Doing the practical is easy, but writing the lab report is not.
For Biology, we learnt how to use the microscope. We looked at some RBC(red blood cells) -- not ours -- E. coli -- you don't have to know what it is -- onion epidermal cells, cheek cells (ours!) -- etc. Again, the lab report is the difficult part.
For Chemistry, I've only been there once, which is today! Our teacher demonstrated some ways to separate mixtures, e.g. cupric sulfate, salt water. She mixed two transparent liquid (not water) and it miraculously turned yellow! It comprised a liquid and solid. She taught us how to separate both of them. An easy way was to just pour out all the water, but it's a little crude. A better way was to use centrifugal force to make the solid part go to the bottom of the liquid. She also burned the cupric sulfate (liquid) to turn it into solid white, and burned one tiny dot of iodine to become purple gas, which was toxic.
I like Chemistry practical the most! I feel like making a mess of all the chemicals and making an explosion. That would be fun. :)

March Holiday QPS 6A'07 Party!
Ma'am has asked me to post this. (I think she will be sending the invitation card later)
There will be a gathering at Queens Condo Function Room on 10 March (Monday, March school holiday) from 4 pm - 8 pm. As usual, it is a pot luck so please bring something. No uncooked food is allowed, as this is NOT a BBQ! Please help to pass the message to other 6A'07 nians.
I will prepare ice, syrup drinks, marshmallow (3 packets) and ice lollipops.
As the swimming pool water is very cold in the night, a good time to swim is from 4.30 pm to 6 pm. If you are not swimming, you can play basketball (bring your own) or badminton too. Dinner will be at 6 pm.

Swimming lesson
Today is my second swimming lesson. It was really a torture. Of course, I still cannot swim. and I think I never will.
At the Clementi Swimming Complex, we gathered at 7.45 am. 3 classes (101-103) were divided into 4 groups, with the forth group consisting of those who could not swim. Of course, I was in group 4. Of those in group 4, I was still one of the worst. Luckily, I was not the worst, Jonathan was :-). At least I am quite happy about that. I always somehow just took in water whenever I went underwater and kicked my leg at the same time. However, today I managed to use my nose to blow bubbles in the water, and opened my mouth when I was out of water.
I have five more lessons to go .. urgh!!

AMC10
Yesterday I took the AMC10A (American Math Contest) paper at 3.30 and was dismissed at 5. I answered all the 25 questions except 1 as I did not know what it means. When I went home, I checked the answers with my sister who also took the same AMC10 paper. I made a very careless mistake on 1 question and the question I did not do was actually extremely easy when my mother explained the question to me. If only I answered these 2 questions correctly, I would have gotten full score, or somewhere close.

Just some funny videos...
Just some videos to help you learn chemistry and history the fun way ... the first one, you can learn about periodic table (chemistry); the second one, you can learn about how Sir Stanford Raffles founded Singapore (history, however this is not true just for laugh only).

Life at National University of Singapore High School of Mathematics and Science (NHS)
I have been in NUS High for almost a month now. The last time I cut my hair was on 30th of December 2007. Now, my hair is already touching my ear. I shall now write about a not-so-boring boring day
It was just yesterday only. The first period was Mathematics, which I was exempted. So I went to the canteen for break. After the break was another break! Imagine the first 2 periods are breaks (for info, I have 5 breaks on Tuesday!). After the 2 consecutive breaks was Geography -- boring. After that was Biology. We used a microscope to look at things. We zoomed in the millimeter mark of a transparent ruler. Do you know what I saw? The milimeter marks appeared to be drawn by a chalk - thick line with chalk-like texture. Later, we examined a small piece cut-out from a newspaper page, which looked no different from many strands of hair. Lastly, we looked at red blood cells. I zoomed in 4x, which are as small as sand. I zoomed in 10x, which looked smaller than a small pimple. I zoomed in 40x, which looked like medium pimples. We were so engrossed in the microscope that 30 minutes of our next period (Chemistry) was gone without anyone realising. We quickly rushed back to the classroom, with only 15 minutes left (in NUS High, each period and break is 45 minutes).
After Chemistry was break, but not for me, I had to go to class 202, where Nicky (my sister's classmate at QPS) is, for Year 2 Maths lesson, since I was exempted from the Year 1 maths. It was more boring than the Year 1 Maths. I bet no one in the class was paying attention. The elective Maths modules (Advanced Maths Olympiad IV, and Combinatorial Game Theory) that I attend on Saturdays are more interesting.

Rubik Unassembled

My Rubik Puzzles
Below are the rubik's cubes I have:
Original 3x3 Rubik Cube. This is the first cube I have, years ago. My record is about 1.5 mins.
4x4 Rubik Revenge / Master Cube. My mother bought this for me after PSLE. Now, one piece at a corner broke off as I have played it so many times - my record is 4.5 mins.
5x5 Professor Cube. My mother bought this for me after I am tired of playing the Revenge Rubik. Similarly, one cube at the corner has broken as it was "over-played". My record is 10 mins. There are no 6x6 and 7x7 cubes available, however, I have tried them on the GabbaSoft Cube (a software - you can turn using a mouse click). My record for 6x6 is about 10 mins, and 7x7 is 30 mins.

Friends, Teachers and Subjects in NUS High
I finally met all my teachers, but I think I had forgotten some of their names. 2 of my friends are Kendrick and Kenryk. Their pronounciation are really close and I sometimes got mixed up. Kenryk has a darker skin than Kendrick. Kenryk really looks like a non-Chinese, but believe it or not, he's taking higher Chinese! And I'm not even taking higher Chinese. There is also one of my friends called Yos and his skin is as fair as mine. But sometimes the truth might be far from what you think. He's taking Malay. Guess how many Malays are there in our class? There's only him! Here's another more unbelievable fact--there are only 3 Malays in the whole year one. There is something weirder in class. A girl, Shi Ni, from our class is just a normal girl. However, I don't know why, and since when, everyone in our class starts calling her mash potato (I think it is because shi ni sounds like shu3 ni2 which means mash potato). She was the mentor rep and the math rep initially, but then, the math rep was changed to Jonathan.
About my teachers -
Maths - Mr Lee - he is loud, whatever he covers in class I already know
English/Mentor - Ms Lau - she likes to nod her head
Chinese - We just call him lao shi - he talks so fast that sometimes I can't catch what he says
Geography - Ms Chen - my favourite past-time is reading the map and also finding out information from the Atlas like population, change of population, life expectancy, death rate for each country, so I think I am going to like this subject
Chemistry - Ms Koh - so far we have not really started
Physics - Mrs Oon - I think I like this subject
Biology - Ms Ng - I also enjoy Biology I think
Music - ??? - so far so good, quite easy although I have no music background
I did not select Literature and History this semester. I think in NUS High, we can choose when to take the Art & Humanities subjects. For languages, Maths and Science subjects, we must take them throughout the years. But we must satisfy the minimum modular credits for the subjects. So I will do Literature and History in semester 2.
Today I took the Diagnostic Test for Maths. It will allow me to get exemption for the Maths modules that I am already familiar with.

NUS High orientation
Day 1
It was my first day in school, and I was late! It was because the alarm clock did not ring. We were supposed to gather at the hall, in our mentor group. However, I did not know where to sit, so I just sat at the back. Later, someone (orientation PSL) showed me where to sit. The announcements were really long. We practised the school song, which was very long. We also said the school creed (what for?), several times, but I still could not remember both of them. After that was break time. Guess what's for break? It's my worst nightmare! I hate noodles. And what's worse than noodles? Noodles + chilli. I drank more than half the bottle of water, although I knew it would not work. Next, we went to the hall again for some briefing. The lunch was rice. Next, it was mass dance at the hall, followed by a school tour, and finally, we went back to our respective classroom to meet our mentor (like form teacher). There were 23 of us in the class, 15 boys and 8 girls. We were given a haversack each with orientation T-shirts and a game. My game was a puzzle key, some students got rubik's cube (round shape). We played some games there till 5 and created a class cheer till 6. And after that was the best part of all -- dismissal.
Day 2
I was late again, for no reason, but at least ealier than before. The announcements were as long, and as boring. We went for break. It was still noodles but at least there was no chilli. We went for mass dance again and then for lunch. Rice again, as usual. Later, we went to the auditorium again for CCA briefing. Next was the CCA fair. We played Math & Science games that almost had nothing to do with Math or Science. After that, we went to our classroom, again, for contact time with our mentor and PSLs. And the best part is, you've guessed it -- dismissal.
Day 3
Yay, I was not late today! The announcements were shorter. Mass dance again at the hall. Later, we had the not-so-amazing amazing race. It was super extremely tiring. We had to travel all around Clementi. After the race, we played with water bombs and we got really wet. We changed to our formal wear and had photo taking. Since I did't have my formal shirt (no stock for my size - the smallest size 13), I wore my polo shirt. One of the PSLs said, "Die Die must wear formal shirt!" So I borrowed someone's. It was so big that it touched my knee. Later, we went to have dinner at the canteen. Rice again. Then it was the Investiture Ceremony. We heard cheers from the Year 1s and riddles form the Year 3s. At about 9, we all went to the concourse for the mass dance and school cheers. I hope I do not have to do the mass dance again in the future.
We reached home at about 10. It was a tiring day!!!

Cool Stuff
CUP & COOKIES: Smart cup in which you can put 2-3 of your favourite cookies. You don't extra plates. It's made for right handed and left handed.
LOCK-CUP: Anti-Theft Coffee Cup. Are you tired of others stealing your coffee cup? Well now there's a solution. The Lock - Cup has a hole which prevents most people from using it. Only the owner of the cup can use his/hers shaped key to close the hole.
TRANSPARENT TOASTER: You love toast, but you always burn it? Than, this invention us for you. This transparent toaster allows you to see the bread while it is toasting so you just have to take it out when the colour is right. This idea is based on a transparent heating glass technology.
"THE THING" - INFANT PILLOW: The Zaky is an ergonomic infant pillow designed by a mom to mimic the size, weight, touch, and feel of her hand and forearm to help her baby with comfort, support, protection, and development. The Zaky can help calm your baby and help your baby sleep better through the night.
TRAVELER'S PHRASE BOOK T-SHIRT: If you are traveling a lot and don't always know the language of the country you are visiting, then this T-shirt is for you. It has a phrase book printed on it so just point a finger at the pictogram you need and then point it twice at the question mark, which means, "Where is it?" and in no time you have found what you were looking for or not.
