Ramblings of a School Teacher

305 temperature Quiz

2011-08-02T08:09:00.001+08:00

Welcome to the new year!

2011-01-05T10:56:00.000+08:00

Haha... this is five days late but better late than never.

Here is welcoming the class of 305 to the world of Physics. Yup, Physics is the KING of Science!!! Haha...

Here is a little cartoon. Reminds me of when I was in my undergrad days. Taken from www.sciencehumor.org

Well, do hope to keep this blog alive and post regularly. Must say sorry that my personal blog is blocked cos I do want to have some privacy in my thoughts. Haha... a teacher is only human and needs to rant sometimes.

Catch up soon!

Not exactly a video where you can learn science concepts. It's a video that pokes fun of the pace of technology and the antics Apple uses to hook consumers into their products.

If ever such a product comes onto the market, please DO NOT buy it. Even if it is from Apple. Or from Microsoft. Or from Toys R Us.

Power of Friction 2!

2010-07-16T10:29:00.003+08:00

The classes are supposed to do a project on making a video on a Physics concept. I decided to make a video too during my remedial class to show them on how much frictional forces can be.

So fun! Definitely will try to video other demos soon. Can't wait to see the other groups video.

Power of Friction!

2010-07-14T15:24:00.002+08:00

totally impressed by the amount of friction in this video. Never knew that the frictional forces can be so great!

side note.... finally decided to post something new again. haha... I must find the time and make the effort to blog more often!

Could this be the way our computers work in the near future?

2009-08-26T13:13:00.002+08:00

I love Apple. The company, not the fruit.

I love the way they bring concepts into reality and constantly innovate their line. And that's only bad because it makes me want to spend money each and every time they release something new.

The Apple tablet rumour has been flying around in the internet for the longest time but this short youtube video demonstrates the power it could have.

Totally cool.

And if it comes out, I am so getting it too.

Teachers Day 2009

2009-08-11T17:33:00.002+08:00

Got to know someone through Twitter. He happens to be the one designing the Teachers' Day website.

Students, please do take time to appreciate your teachers this Teachers' Day. Drop a small note to your teacher to let him/her know you appreciate the time he/she gave for you.

Take time to appreciate the teachers who made a difference in your lives.

For East View students, I do hope to see your entries in the website to encourage the many teachers in school of their hard work and dedication.

HD Trick Challenge

2009-07-29T07:26:00.002+08:00

Fantastic video! Saw this on someone's tweet and was amazed at how they did it...

Of course like all people I did not pause to think of the answer and immediately clicked on the answer revealed video...

Simple answer right? But the preparation is so super complex if you think about it.

I want to do something like that too! Anyone out there interested to get it started with me?

I can be a prop in the video. I sit really still.

Longest Solar Eclipse so far...

Sec 3 Science Project 2009!

2009-07-20T09:53:00.003+08:00

Yeah! It's the annual Pythagoras' Switch Project. I am beginning to look forward to this project as the students ideas are becoming more and more innovative as the years proceed. My aim to be able to flood youtube with the students' videos this year and hopefully come up with some ideas for TKK Young Inventors' award!

And finally one project from last year!

Have fun!

Student's view of Heat Transfer

2009-07-15T08:31:00.000+08:00

Unburnt paper

2009-07-13T18:10:00.001+08:00

The coin, which is a good conductor of heat, transfers the heat away from the flame and prevents the paper from burning up.

Water is a bad conductor of heat

2009-07-13T18:02:00.001+08:00

The ice at the bottom of the test tube fails to melt even though the water at the top is boiling. Water is a bad conductor of heat and the heat at the top does not conduct to the bottom of the test tube.

Convection

2009-07-13T18:00:00.001+08:00

Now teaching on transfer of thermal energy. Was telling 305 about convection. Here's two videos on it.

Cold Boot Attacks

2009-07-03T09:25:00.002+08:00

Wow... this video is awesome! Normally I will think that the information from RAM is wiped out the moment power is cut from the computer. But this research shows otherwise! The information from RAM is kept from seconds to a few minutes and if the temperature is cooled down by using simple tools, the information can be kept for up to 10 minutes! Wow.. this means that if the RAM is being transferred to another computer, then the contents can be read... encryption keys can be stolen and private information is no longer private... or like what this research shows... RAM reading software can be developed and usedto decrypt the information just like that... Scary thought.

How then to protect your information that is stored in computers? Make sure it is not stolen physically!

First day of Term 3 and 3rd week of my attachment!

2009-06-29T15:39:00.002+08:00

This is the 1st day of school and ... I am not in school! I am still on attachment at A-STAR and honestly I am quite bored here... Have just been reading and reading. I guess that can't be helped as the area is something I am not familiar with and it is hard for my mentor to assign me something to do when I have absolutely no idea what it is about...

Haha... good thing is that after two weeks of reading... I am able to ask simple yet intelligent questions. I know they all say there are no stupid questions but somehow I cannot bring myself certain type of questions when the answers are pretty straightforward and can be found by simply reading. I am not one who is able to ask questions off the cuff... do envy those who can just ask question after question to clarify their doubts. If I don't ask any questions, does it mean that I have no doubt or that I don't care if I have doubts or not.... haha...

Going back to the first day of school back in EVSS... do hope that everything went on smoothly... the H1N1 flu situation is constantly evolving and the instructions are constantly changing... teachers are trying to appear cool and calm... as for students... do hope that their learning can still continue as per normal... especially for the graduating classes... this last stretch is very crucial for them and they will need every minute of preparation to ensure that they will do well for the O-levels...

To my classes... I have engaged a relief teacher and gave instructions on what to do.... please do not give the relief teacher any trouble and cooperate with him to the fullest... Do leave me tags on my tagboard if you have any queries so that I will be able to answer you...

Seriously missing school... haha... feel like a student all over again... massive amounts of readings... earphones plugged in almost permanently... constant headaches from the readings...

1 week so far...

2009-06-23T13:21:00.002+08:00

I am quite bored at my attachment. Honestly.

I find myself trying to find something exciting to do but honestly, it feels like my university research all over again. Haha... didn't exactly enjoy the research process in U... but the action research in teaching brought back a love for learning again. A love for searching for new knowledge. Sometimes teaching makes you complacent... coming to A-STAR makes me realise that I am very backward in my knowledge of the things that has been happening... makes me excited to want to learn again..

So I will try to find something exciting to hook onto... so that when I go back to school, I will have something to transfer to my students... to excite them to go beyond themselves and dream...

View from my workplace

2009-06-15T15:33:00.001+08:00

As promised, this is the view from my workplace and it overlooks ACJC. I know it is nothing fantastic but it sure beats seeing 4 walls every day. Nice!

Research attachment @ Network Storage Technology (NST)

2009-06-15T11:39:00.003+08:00

Today is the first day of my attachment @ NST, a division of A*STAR - the premium science research institute in Singapore. Last week was my induction and indeed I must say I was wowed by the state and level of research in Singapore. I attended talks by various group leaders in A*STAR on bioethics, the learning of Science and their research work etc. Wow! I was honestly quite impacted by their sharings and was quite of Singapore of what she has achieved through A*STAR.

What was more surprising to me was how each and every one of the people working in A*STAR is so proud of their work individually and corporately. It is normal for them to feel proud of their individual knowledge. I mean, they are among the best in their field to be working here. But corporately, they really sing the same tune! I am attached to NST and my mentor is Dr Khin Mi Mi Aung, from Myanmar. Boy is she passionate about her work, A*STAR and NST. She sings passionately about the work of not just NST but about almost all the other different organisations under A*STAR. Wow! And she's not even Singaporean. As a Singaporean, seeing now the reseach capabilities we can offer, I am super proud of the advancement in science that comes through our hard work.

Side note, I do have a great view at work. Will take a photo of the view I have in my lab. An unobstructed view of Singapore from the 14th floor!

Ok got to go for lunch now!

I know I know...

2009-06-08T21:49:00.001+08:00

I know this video is on Ms Ang's blog... and on class 406 blog... and on my other blog... nothing to do with Physics but a super hilarious and creative way to get people to realise washing hands is very very important!!! Haha... can't believe sometimes I see people walk out of the toilets without washing hands! My gosh.. yucks!

Fleming's Left Hand Rule

2009-04-23T13:02:00.001+08:00

Teaching 502 today and was quite shocked that some laptops still don't have flash installed. Luckily found some videos on youtube to show them.

haha... my 'fav' blogger blogging about Science Centre!

2009-04-22T10:26:00.003+08:00

I have always thought most of the exhibits at Science Centre are very cool... not all are well maintained... some of them are 'ancient'! haha.... I remembered the electric chair and I think it was there since I started going to Science Centre in Primary school.... and that was a long long time ago!!

I wish East View is nearer to Science Centre.. this way, I will bring students more often there... and perhaps conduct lessons there... a change of environment also hooks students and interests them to study better...

Yup, this is totally amazing! hahaha... go and buy a 50 cents wooden ruler and try it out!

Physics Songs

2009-04-17T12:09:00.002+08:00

In an attempt (some may say desperate attempt) to elevate Physics into the state of coolness, we write songs about Physics! One video is done by a teacher in Singapore... haha... guess which one har?

TV Ad for Family

2009-04-17T11:49:00.004+08:00

The first time I saw this ad, I was touched... the many beautiful imperfections in our partners that make our lives complete... thought the poignancy of the moment was captured wonderfully by the director... I know that has not much to do with Physics... well you can say the part where she was describing the motor sounds... you will learn about the motor in Physics in Sec 4...

But education is sometimes not simply learning about the facts and figures... the journey is equally important... learning Physics is not just learning about the facts and formulae... it is also about the journey of a student trying to grasp the amount of information around him and making sense of it all...

Don't give up on learning... certain things may seem to be difficult to understand but if you take some time to read through and think about the topic, I am sure you will be enlightened!

Just survived CNY

2009-01-29T11:03:00.002+08:00

Wow... never had such a tiring CNY before... man... bringing Joash around to go visiting is really tiring... must juggle his feeding and sleeping schedule with our visitation... man... he just can't sleep cos there's so much activities going around him... can't blame him... cos he's so CUTE!!! I know I am biased as a parent but I honestly think he's very cute! Everyone's like carrying him and talking to him... how to sleep like that? The moment he's back in the car travelling to the next place, he immediately KO... and he promptly woke up at the next place... haha... he's so tired out by the end of the day... he fell asleep even before he hits the bed...

Now that back to school... back to the reality of my students' results... sigh... last year they really didn't do well... some were too complacent but generally I feel the cohort was not putting in effort... but this year I feel the students are starting off well... way to go graduating batch of '09! Let's work hard together to bring forth the best results ever!!!

Will look for nice videos to post soon... Mr Ng got some mean looking vids on his blog... go check it out!

Week 3 of 2009

2009-01-21T15:31:00.003+08:00

I have been swarmed with work since the beginning of school... but am happy doing some of the work especially when I see some of my students putting in hard work for their lessons. The school I am teaching in caters to the lower ability students and generally their motivational level is not very high. To enthuse them and steer them to aim higher for themselves is an art. I am constantly training myself to perfect this skill yearly.

This year, I do think that the classes are more motivated. I am not claiming credit cos I don't think I did much. The school on the whole did a lot to improve the tone of the environment and I do think that it is taking effect. As a teacher, it gives me great joy to see a recalcitrant student turning over a new leaf and putting in effort to take charge of his/her life. I am seeing more and more such students and honestly, I am very proud of them. It is not easy to put brakes on a downward spiral especially when everyone around you is not doing so. I am proud of these students who are able to put brakes on their self-destructive habits and break free from the habits. I often wonder what will be my response if I were in their shoes.... I am proud of them because I think they are better than me when I was in my younger days. They put brakes on themselves, make a big U-turn and push themselves on against all flow to better themselves.

Man I am proud of these students. But I do hope that their change will last. It is not easy to build lasting change but I do hope this bud of change I am seeing is one of permanence. I will do all I can to water, nurture and grow these budding talents into maturing pillars of the society.

I will. I can. I am.

KING OF SCIENCE!!!!

2009-01-01T23:05:00.002+08:00

Physics is the KING OF SCIENCE!!!! Haha... this is my tagline for all my new Physics students... My ex-students will remember how I used to shout this whenever I see them and they used to shout back at me the same tagline... the two videos are definitely a testimony of that!

How time flies and it is 2009. A new year has started and I am definitely looking forward to seeing new faces again for my classes. Although I know that making new year resolutions are definitely not my strength, I do want to try to maintain this blog more often than 2008. Haha... and I ensured that I will do this by making sure people pressure me now and then..

So you students out there... if you see this blog languishing in cyberspace... drop me a tag or just let me know in school!

Physics is the KING OF SCIENCE!!!

Joash has arrived!

2008-09-05T07:14:00.000+08:00

My baby boy Joash has arrived in this world on 1 Sept 2008 at 8.35 am weighing a whooping 3.68 kg! Woohoo! The first time I carried him... the whole moment felt so surreal... you know... like when you anticipate anxiously and eagerly for something to happen and when it finally happens, you think that this cannot be it... he looks so cute! Not just because I am his father... but honestly I think my boy is the cutest!

Will post pics later... but serious lack of sleep now. Wife had a c-section and needed time to recover as her wounds are very painful which leaves only me to run around and get everything done... 3 hourly feeds and the stream of visitors... leaves me no time to rest...

Yeah! I am now officially a father! And next year... FINALLY... I can start receiving hong-baos again... for baby Joash... hehe....

2008-04-11T16:52:00.002+08:00

Just finished the chapter on radioactivity with the students. So sad that this chapter is left out in the new syllabus. Very interesting chapter to talk about and teach. Oh well... here's a video for you to enjoy learning about radiation. Haha... in class we had interesting discussions about the radiation killing sperm and eggs, about how radiation causes cancer and we really do not know what is in our foods these few days...

Suck Egg into Bottle

2008-04-06T20:44:00.001+08:00

This experiment can be tried at home with proper adult supervision... haha... v cool!

Radioactive decay

2008-04-02T23:32:00.000+08:00

A simple animation about radioactive decay.

Radioactivity Experiment

2008-04-02T23:30:00.001+08:00

A very clear video about radioactivity.

GM counter

2008-04-02T23:29:00.001+08:00

GM counters... instruments to measure radioactivity. This video is more for instructional purposes.

Awareness Test

2008-03-20T23:48:00.000+08:00

Really blows your mind.

Lenz's Law

2008-02-20T16:52:00.001+08:00

Watch this video to clear up some concepts for the chapter on Electromagnetic Induction...

Electromagnetism

2008-02-20T16:51:00.001+08:00

Density Experiment

2008-02-20T16:45:00.000+08:00

haha... love this video... cos it reminds me of the days when I was training as a teacher... when we all had to make a short video to demonstrate a Physics principle...

Magnetic effect of Currents

2008-02-20T16:41:00.000+08:00

For the topic on magnetism, this video shows the magnetic effect of current flowing in a wire.

Magic of Physics

2008-02-20T13:28:00.001+08:00

This is always my intro to lessons! Physics is the KING OF SCIENCE!!! Woohoo!

Amazing Magnets!

2008-02-20T13:25:00.002+08:00

Haha... my first new post in over a year!!!! OMG... Must ensure this year update the blog more often...

Very cool experiment! (pun intended if you know what I mean... haha...) Anyone wanna hazard a guess at why this can be done?

Calendar online

2007-03-12T23:30:00.000+08:00

Dear students,

I went for a Teachers' Conference and found out a useful tool and hopefully this helps you in the learning in my class. I have placed an online calendar and posted things I need to remind you online. Do hope this will help you plan your time well and helps me make sure that announcements are made to all. But I do need a favour.... which calendar is better? Google one or the 30 boxes one? I like them both... kindly drop me a line on the chatterbox to let me know. Thanks!

Crushing Can

2007-03-06T21:37:00.000+08:00

Absolutely love youtube! Man... was thinking of this experiment and wondering if I can do it in class for my students... if my pure physics students are reading this blog now... the above videos are for the chapter on Pressure.... searched youtube for videos and voila! Found two videos on the crushing can.... one with detailed instructions and clear explanations. Do look through the videos... you are encouraged to try it out under adult supervision.

Cool Computer Program

2007-03-06T11:06:00.000+08:00

Wow! I will love to have this program! So cool... students in my class know that I draw a lot on the whiteboard and this program will be so useful to me when I need to illustrate any examples and animate them... Haha... my sec 5 students will love it because at least EM induction will not be so abstract and complicated.

Wow... my brain is still reeling over by the possibilities that I can do with this computer program.

Jim Carrey and Conan talk Quantum Physics!

2007-03-06T10:54:00.000+08:00

Haha... had a good laugh over this clip! I bet both men did not know what in the world are they talking about... love their looks! Man they look like students in my class sometimes when I go on and on about the concepts and they have no idea what in the world am I talking about...

I must apologise for the slow update of the blog... Today I took sick leave cos this fat body of mine is taking a long time to fight the flu... man my back is aching like mad and I cannot walk without feeling the pain in my back... Had a tough time in class yesterday so rushed off to see the doc at the end of the day... now taking the medications... Drowsy but hopefully my flu will get better cos I WANT to go BACK to school... cannot believe I am saying this but I do want to go back to school... I want my students to study (although I know a lot of them are not putting enough effort) but I know they will not do work when relief teachers are there...

Sure hope I will be better by tonight... Pray for healing for me if you are a Christian... pray that God will heal me fast!

I know...

2007-01-21T23:34:00.000+08:00

It's been a while since I blogged on this site... give me some time... will try to blog something... soon...

Martial Arts Physics

2007-01-14T22:33:00.000+08:00

The video shows how accurately the martial arts experts can jump.... and the path they take must correspond to the theoretical path computed by Newton's equations of motions... That's why Physics is the KING of science... the accurate prediction of what should and could happen simply with the basis of theories and equations...

Quantum Physics

2007-01-09T23:01:00.000+08:00

This is not in the syllabus for secondary Physics and is only briefly introduced in A-level Physics... To my older students who are reading this blog, this video may have more relevance as it attempts to shed light and understanding on the initial confusion about quantum events, that occurrences are purely random and arbitrary. The final result of the quantum events cannot be accurately predicted yet with a certain certainty, things can be predicted. Talking in circles? Haha... that's what I feel Quantum Physics is sometimes... I do like the video though and there are many parts to the video... think this is just the tip of the iceberg!

Hurricane Balls

2007-01-09T22:52:00.000+08:00

Thought it is such a simple demo and yet so captivating. Just 2 magnetic balls and a mirror, coupled with coloured lights.... simple apparatus and the effect is hypnotic! Not too sure what can be learnt here... sometimes videos are just for entertainment sake I guess. But if anyone of you out there thinks that there is a Physics concept to be learnt and grasped here, do feel free to leave some comments... Haha... I am also still learning!

Homework

2007-01-09T22:46:00.000+08:00

Yup, this blog is like my homework... I have to tell myself I have to be disciplined enough to blog regularly... at least a few times per week... Haha... that gives me the liberty to surf the web for interesting sites and videos on Physics!

Disclaimer!

2007-01-09T22:40:00.000+08:00

I think it's better to put a disclaimer now... all the videos here are carried out under adult supervision. Please do not carry them out unless you have an adult beside you and please take all safety precautions before proceeding with any experiments.

Wow... cool!

2007-01-05T00:25:00.000+08:00

Wow... I thought this is way cool... though very dangerous! I am not too sure how the teacher did it but I can guess why the students were not hurt. Water has a high heat capacity and the heat absorbed from the flames are taken directly in by the water and vaporises it. In doing that, the students are kept safe from the heat. A similar thing will be using just wet newspaper to mold hot glass (about 1500 degrees celsius). I did that in Japan, molding glass with bare hands protected by only wet newspapers! Will search for that photo and try to post it on my blog... Two of my students also did the same thing as me... Ruwan and Castillo...

String Theory

2007-01-04T22:43:00.000+08:00

Ok... I think this new theory is way out of my students' understanding... in fact I am struggling to understand it myself! One thing's for sure... no one knows how the universe began and survives until now... Newton tried to explain with gravity... Electricity and magnetism theories seemed so revolutionary when they first appeared... Einstein searched in vain for a unifying theory... Everyone is trying to come out with an explanation of how the world is working... or rather how God works...

Have posted a link to a website that has really very nice videos narrating this string theory... Very cool videos but takes time and preferably watched over broadband... If anyone is interested to read the book... can find me... it's "The Elegant Universe" by Brian Greene

How much sugar is there in a can of soda?

2007-01-04T22:19:00.000+08:00

I watched this video and was stunned by the amount of sugar that was actually in a can of soda! Man... I am swearing off Coke... for now... can't imagine me drinking so much sugar....

But this video made me realise that quantities are actually very important in daily lives... except that we do not pay much attention to them... We see numbers with units attached to them but many a times forget the actual meaning of the numbers! 39 grammes of sugar may not seem a lot... cos 39 when attached to grammes... hmm... sounds like a small number but we forget that one small teaspoon of sugar is only about 5 grammes of sugar! So 39 grammes is actually quite a big number in relation to 5 grammes. Besides we are talking about sugar which is not exactly a healthy thing to consume in large quantities.... and by large quantities it means more than the daily required amounts...

In Physics, numbers are important. The universe is governed by numbers (I know.... many of the philosophers out there will be opposing this but let me just say this as a point of view from someone studying physics) and the numbers will make no further sense if there are no units attached to them...

And this is the first important lesson in Physics... numbers need to be followed by their units because then the whole meaning of the information given by the numbers themselves will be made clear to the reader.... Hmmm.... can understand? Haha... I know I am rambling on.... but guess what? That's the title of my blog!

Till I post again...

New Year 2007

2007-01-03T15:28:00.000+08:00

This is a brand new year and I do hope to try out something new for my teaching. I have always talked to my students about the interesting websites that I stumbled upon in my web surfing and showed them in class. However it is hard to have a central reference point with my students as it's not always easy for them to remember all the websites... or that they can't be bothered to go check it out! In any case, I think keeping a blog for me on Physics stuff is good... helps me keep updated with any current trends and keeps me in touch with my students, both present and past.

Do hope that it will be a useful resource.
