IGCSE Physics : Topic 5 Atomic Physics

Topic 5.1- Radioactivity

Background radiation-the small amount of radiation around us all the time because of radioactive materials in the environment. It mainly comes from natural sources such as soil, rocks, air, building materials, food and drink – and even space.
Radioactivity detection- Geiger-Muller tube (G.M. tube)
  
Radioactive Decay

Alpha decay- two proton and two neutron left

Beta decay- Gain proton

Gamma emission- No change of proton and nucleon number

Half life
time taken for half the nuclei present in any given sample to decay. Some nuclei are more stable than others.

Safety Precaution
-radioactive stuff is stored in a lead container, in a locked cabinet
-picked up with tongs, not your feet
-kept away from the body, not pointed at people

-left out of its container for as short a time as possible

IGCSE Physics : Topic 4 Electricity and Magnetism

Topic 4.1- Phenomena of Magnetism

Properties of magnets:
-Has a magnetic field around it             - 2 opposite poles    
-Induce magnetic materials                  - Exert no force on non-magnetic materials

Ferrous materials: iron, nickel, cobalt

Non-Ferrous materials: Copper, glass

Magnetising method- Insert metal into a DC solenoid, induced magnetism from magnet

Demagnetising method- Stroke with hammer, insert into AC solenoid, heat it
Iron= soft ferrous metal ( non-permanent magnet)  Steel= hard ferrous metal

Topic 4.2-  Electric Charge

Induced Charge: a charge that “appears” on an uncharged object because of a charged object nearby, for example if a positively charged rod is brought near a small piece of aluminium foil. Electrons in the foil are pulled towards the rod, which leaves the bottom of the foil with a net positive charge. The attraction is stronger than the repulsion because the attracting charges are closer than the repelling ones.

Current, Voltage and resistance

Voltage= current x resistance     Voltage= energy/charge     Charge=current x time
Resistance factors                                    High temp (semi conductor) = Less resistance

Double the length = Double resistance      Double cross-section = Half resistance

Better conductor = Less resistance            High temp (conductor) = more resistance

Wave front: Peak of a transverse wave of compression of a longitudinal wave

Speed: How fast the wave is travelling (m/s)

Frequency: number of complete waves in one second (1/period)

Period: number of time for one complete wave

Amplitude: Maximum distance from peak to rest position

IGCSE Physics : Topic 2 Thermal Physics

2.1 - Simple kinetic molecular model of matter

Molecular Model

Solid : 1. Strong forces of attraction between particles
            2. Have a fixed pattern (lattice)
            3. Atoms vibrate but can’t change position.

Liquid : 1. Weaker attractive forces than solids
             2. No fixed pattern
             3. Particles slide past each other.

Gas : 1. Almost no intermolecular forces
          2. Particles are far apart, and move quickly, gases spread out to fill up the container and exert equal pressure on all surfaces.
          3. They collide with each other and bounce in all directions.

IGCSE Results Says It All ...

Every igcse result slip has its own story to tell, when i receive the screenshot and pictures of their results slips i find it important to post it up to inspire their juniors. Those who are going to take their exam soon, maybe 3 months, maybe 6 months or maybe 12 months or more, don't give up, just do it. 

I have 2 students who were gamers, we call them MOL points boys, they came to my class with zero chemistry and physics. With some persistent and motivation their results are one of the below. 

Its the hardwork of the school teachers, parents and tutors to achieve such great results. 

In the end, its all about the student we are personally responsible for.

If Only You Are A Teacher

This is a completely random post for the day. I have been a teacher tutor for more than 10 years and its an amazing journey when most people around me remain young while myself getting older. 

My passion to be a great teacher has always been there, started teaching students and now i have to teach my team of teachers/tutors and lead my amazing team of managers. 

For those who are considering jumping into the teaching field, you will find this post interesting. For those who are already in the field, you will find it refreshing. 

If only you are a teacher ....

you will experience ...
 they will steal your phone and then try to take funny selfie with your head in it. 
I think they are trying to poke a finger at my face and another slapping me


if the experiment involves 'fire' and 'explosion' they will be super excited
this experience is scientifically exhilarating 
try butane gas and detergent water


they will always take a random pictures of me at any angle
they can and try to be a professional
and laugh at the pictures they took at the end


 

they are always happy ..... reminds me of minions here..


 they will also try to stuffed all their big head into the small camera of my iphone


 and they force you to take selfie with them .. 
i try to act cute but totally failed here


they will also whatsapp me random pictures of myself on youtube
saying 'wa teacher, this video is helpful pls post more' 

at the end of the day, they score outstanding results 
and that's what it all matters


mums sending me lovely thank you messages 
which gives you a good perspective of what i did 
and what i can do more  




and also they want us to stick around 
to help their sons and daughter in the future.


If only you are a teacher...


Thank you to all the dedicated teachers out there who has been helping weak students to become stronger and stronger students to become great. I believe they are many great teachers out there that we have not heard of, nevertheless, you are an amazing soul who has changed the world by changing the students you teach. 

Thank you teacher

SPM Study Online FREE

I find student have to travel to different places for tuition and parents have to spend lots of time transporting their children to tuition centres and sometimes 2 or 3 places in a day. A student of mine who is studying in a top school in Cheras travels to USJ for a class and then back to Kota Damansara for our classes on a Sunday. I have the highest respect for the parents for putting so much effort to help their son. As a teacher and someone who runs a few centres we find that our greatest responsibility is to ensure our students receive effective lessons, we go beyond parents expectations and add value to their lifes. 

To save time and for the sake of convenience, we have to use technology.

We have produced SPM learning videos, it might not be the prettiest looking videos you can find in the internet but i assure you that i can very much help you with your exams and very effective. Each video has been prepared carefully from quality of content, the layout of information flow, sound quality, lightings control and etc.

IGCSE Homeschooling, Are You Sure?



In our country, when we mention homeschooling,  it will usually end up being one of the two scenarios:

1. Going to centres to replace schooling time; this is what the majority does.

2. Students stay at home and are taught by their parents and tutors, which is the minority among the two options.

For this post, when we refer to homeschooling, we will be discussing option one: which are the student who are being taught at centres.

SPM Practical Exams for 2015 Cancelled

Last year 2014, the examination board suddenly declared they want to stop Paper 3(written practical) and requested all schools to prepare for the lab practical for all sciences. So all teachers in school try to predict explain to the students whats going on. The lab assistants told us about the shortage of lab supplies and a million few problems we will be facing. We finally got it straighten up and we did solve all the major and minor problems to get our students ready., 

Now in Mac 2015, they changed their mind. 

I mean, lets put the teachers problems aside and focus on our students and children. They are already facing enough pressure because of SPM year, and they are already set for the new format and now they have to re-adjust again. It will be easy for stronger students but average to weak students might suffer and gave up. 

All the best to our SPM Students 2015. 

For those who didn't a get a chance to see the letter, here you go.

so next year 2016 confirmed?

'... practical SPM examinations will be delayed to 2016...'


let's hope no surprise last minute changes in the coming months

'..Paper 1, Paper 2, Paper 3 will be unchanged as per previous years...'

'...the letter dated 10 June 2014 is now cancelled...'

You can view the letter from the Lembaga Peperiksaan Official Website
or just click the direct link HERE


This matter we may reflect on 

Positive 
1. Our MOE is actually making changes in hope to improve the education system
2. They are open this time since they posted up the official letter with errors.
Negative
1. Plan ahead and execute with plan 
2. They need to communicate with teachers and staffs who are on the field facing students each day
3. No reasons for cancellation were stated in the letter or any other portals
Well! Good Luck!
