The Magic of Immersing Thread Into Ice

Well today we did have a very interesting experiment, some might think that this experiment is dull and way too simple, but when you really try it out, you will eventually realise that there is a lot of things to learn in science especially the fun way

The person in-charged for today's meeting was no other than Ong Meng Teck

So our aim today was to make sure that the thread goes through the ice slightly so that we can lift it

In order to achieve it, we use either Pressure concept or Reducing Melting point concept

For the pressure concept, we used 2 pendulum bob and tie them together with a thread. Then this thread is rest upon the ice thus providing the pressure needed.

As for the the Reducing Melting point, we used salt which in this case we used Potassium Chloride. By placing the thread on the ice and then pouring some salt on the thread, the salt will cause a reduction in melting point of ice thus the thread will go through the ice easily. When the water on the ice dilutes, the melting point is then restored to it's original value thus freezing back slightly.


Enough of points, now picture time

A great way to apply pressure

Our teacher advisor explaining the theory

There will be more experiments to come in the future!

Smoke Bomb

Well we have long awaited for this experiment to clearly see the result of the smoke bomb experiment

So what we need?
1) Potassium Nitrate
2) Sugar

All we need to do is heat it up together in a ratio of 1:1 and once it turn caramel brown and melt, turn off the bunsen burner and stir it. Then put it onto an aluminium foil and let it cool down.

Upon doing that, we bring it to our school field and burn it. The result was awesome.

Unfortunately due to some circumstances, we do not have any media to upload for you to view. Our sincere apologies.

Summary For The Year 2011

Yes, the club will no longer have any meeting as of this year, but we however will still continue to plan more activites in the future

Here's a list of what the new committee has done for the year:

1) Hot Ice Experiment
2) Moving (Rowing your Boat)
3) Brain Mashing time
4) Elephant Toothpaste
(The order of the experiment is not in any sequence)

Unfortunately we do not have a review on the elephant toothpaste due to the unavailability of recording device during the day

Most of our experiments are fun and you probably might not have thought of it, so here you go

All we ever wish is that our members enjoy every single meeting with a smile in their face

Do stay tuned for more updates!

Hot Ice Experiment

 Prepare the materials and apparatus as below:

(a) Sodium Acetate

(b) A beaker

(c) bunsen burner & wire gauze

(d) distilled water

(e) ice

 set up the apparatus as shown above

cool it down without disturbing it

this is what you can see after added crystal

1. Put 2 tablespoon of sodium acetate in a flask.
2. Heat gently and stir until the crystals of sodium acetate melt. Use a small amount of water to rinse down the inside of the flask.
3. Remove the flask from the heat and let it cool slowly without disturbing it.
4. Add one or two crystals (that’s right, it only take a single crystal) to the liquid in the flask. Don’t take your eyes off of the liquid as beautiful crystals begin to form inside the flask.
5. Feel the flask… it’s warm! The process of crystallization gives off heat. It’s said to be exothermic.

WanVoon and BaoYun were enjoying :D

Brain Mashing Time!

Yesterday, the Form 6 Science and Mathematics club have different plan instead of the ordinary mixing 2 or 3 reactants and BOOM! A reaction takes place

We instead let our members do some IQ questions which are considered tough, yet suprisingly our members managed to answer most of the questions correct.
After all there is the word "MATHEMATICS" in the club name and giving "SCIENCE" a rest was probably a good thing to do once in a while.


You might probably be wondering what sought of questions did we gave the members to do, here is a few:
1. Sequence of numbers
1 11 21 1211 111221
What will be the next one in the above sequence?

2. Divide the clock’s face into three equal parts exactly with two lines. Therefore the sum of the numbers in the three equal parts should be same.

3.  Some months have 30 days, some months have 31 days, how many months have 28 days?



Aren't those questions tough? I bet it is

Now picture time :)

Questions on the board, hard to read making it harder for them to answer!

Our secretary working with our teacher advisor, Pn.Chan!

The "Pro's" paper

Hmmm....

A : Can you get it?
B : Let me try! (HITTING THE CALCULATOR BUTTONS)

Our V.President showing our members how to solve the question

Cool!

Members laughing = Good Thing? Yup

Solving more problems

Feeling the intensity?

All 4 have different pose?

Thinking face

"This is too easy"

"haha, haha, haha"(staring at the questions)

Our committe are also solving it with them

President explaining giving a review on some questions!

ooh! Everyone wondering what the answer will be

The mini-discussion

Further explanation needed? maybe not

 



That's all

And another thing,

Good Luck To All Members in Their Upcoming Exam!

GOOD LUCK
