When you're at the website, click on 'download file' and voila! ;)
The document is 32 pages, which is a compiled version of the entire secondary 3 to 4 social studies textbook, done by me! I can assure you that all you need for 'O' levels is this document, and lots of practice! Do make sure you have memorised at least 2-3 different THEMES, not chapters, but THEMES.
Do take note that I did not compile the 'Globalisation' chapter since this topic has already appeared in 3 consecutive years!
All the best to those taking their 'O' levels!

Friday, June 10, 2011 - [ Geography: Development ]
Here are notes on development, for Elective Geography.
Reasons for uneven development.
1. Historical Reason - Colonialism
- Colonialism is domination of more powerful country over another country
* Colony = dominated country ; colonial power = more powerful country
- Colonialism affected way in which many countries develop
Case study #1 - Colonised in the past à Former colonies remained lowly developed
-One reason for colonialism was colonial powers wanted to obtain valuable raw materials which could not be found or grown in own countries
-Portuguese colonized Angola in 15th Century and set up plantations to exploit favourable physical conditions and availability of labour à climate and soil conditions suitable for growing cash crops
-Cash crops would fetch high price in Europe and exported them for sale à strong trading relationship between colonial powers and colonies
-Advancements in technology allowed Portuguese to add value to raw materials by converting them into useful products and sold for higher profit à Colonial powers able to achieve DC status quickly
-Development slow in colonies as other aspects of development like education and environmental sustainability not developed à colonies remained poor
-Disparity in development continued to widen
oDCs continued to develop technology and industrialise further, former colonies continued to export low-value raw materials and gained little profit
-Former colonies earn less $$ à low GDP per capita à low standard of living and quality of life à indicating low level of development
Case study #2 - Colonised in the past à Former colonies prosper & highly developed
-Colonial powers brought technology and skills to the colony, allowing them to advance and enable economy to prosper
-Singapore was colonized by British in the past due to its strategic location
-British built infrastructures and improved port to enable trade and allow Singapore to be self-reliant in future
-Singapore now able to continue to prosper and not only focus on trade but also other aspects of development like education [2nd highest spender in Singapore’s GDP]
-With higher education level à more emphasis on tertiary and manufacturing industries à higher GDP per capita à High standard of living and quality of life à indicating high level of development

- [ English: Oral Exams ]
Okay, apologies for not writing for almost 2 years.
English (syllabus 1127) is a very important subject we take throughout our school days, and we need it to be able to communicate fluently with others, so here are some notes with regards to the oral examinations. This section consists of three different components - reading aloud, picture discussion, and conversation. The total marks is 40, and takes up 20% of the whole subject.
Here are the objectives of the oral examination, based on the updated syllabus set by the Singapore Examinations and Assessment Board (SEAB) for those taking their 'O' levels in 2011,
#01. Reading aloud (12 marks) :
(i) Pronunciation and Articulation: read a passage with good pronunciation and clear articulation
(ii) Rhythm and Fluency: read with appropriate rhythm and stress to achieve a well-paced, fluent rendering of passage
(iii) Expressiveness: read with appropriate variation of pitch and tone in order to convey the information, ideas and feelings in a passage
#02. Picture Discussion (12 marks):
(i) Interpretation and explanation: interpret and explain the situations in the picture with supporting details.
(ii) Language: use a range of appropriate vocabulary and structures to complete the task
(iii) Coherence: develop ideas in a clear and coherent manner
4 easy steps to score in picture discussion -
1. Look at the location or surrounding environment: always choose the one which you can explain with evidences from the picture, example the attire or facilities.
2. Deduce what the people are doing and explain your answer.
3. Look at the faces of the people in the picture: Choose two of the most outstanding people in the picture and not only describe the physical appearance of these two people, but also describe their emotions and thinking based on the action. (Infer!)
4. Social Implications: What impacts would it have in the future? This can be said within 3 or 4 sentences. Example: active citizenship - take care of the less fortunate in the society and start young so that it becomes a habit as they grow up.. Develop in them a sense of compassion for fellow people.
#03. Conversation (16 marks):
(i) Personal Response: give a personal response to the theme of picture and the passage
(ii) Clarity of Expression: express himself/herself clearly and succinctly in a conversation using appropriate vocabulary and structures
(iii) Engagement in Conversation: discuss issues that arise with the Examiner stemming from the picture and the passage
Always take note for conversation, you are talking to a person, not making a speech. So use proper English, but at the same time, don't sound too formal, or it will not be a conversation and more like a speech.

Samples of Good Descriptive Writing: Credits to Mr Denis Chin! A Traumatic Experience
The clouds lingered in front of the moon, blocking it out. My best friend, Tim and I were waiting impatiently for our noodles at our usual haunt. The food centre was still bustling with people although it was late in the night. The noise from the noisy crowd and over-worked fans force my friend and me to converse louder than usual. The aroma of the grilled satay drifted into my nostrils making my mouth salivate.
Being hot-tempered and impatient, I walked to the stall holder and bellowed at him, "Old tortoise, faster! So old and slow already, you should be lying on the bed in the old folks' home like all the other old retards?"
"You fat and ugly pig, can't you even wait a little longer for your food?" the stall holder retaliated in fiery, throwing his old and filthy rag at my face.
Casting the rag aside, I stomped angrily towards the stall holder. Before I knew it, a bucket of mucky an smelly water was thrown at me. With the dirty water dripping from my clothes, the crowd pinched their nose and avoided me as they walked pass.
I stomped forward, clenching my fist. Raising my fist to his head level, I punched him with all my might. He was blinded momentously. In my anger, I snatched the money from the cash register and threw it all over the floor. The coins an notes scattered out.
The stall holder, hearing the coins landing on the floor, went berserk. He took out his chopper and wield it dangerously around. Finally, he landed the knife on the table, and it cuts through my right hand, severing it.
I was petrified by the sight. The blood gushed out from my hand. I fainted at the sight of the blood.
I regained consciousness, hoping it to be anything but a nightmare. However, I found myself lying in a pool of blood. My friend was trembling in front of me. The gruesome scene sent shivers down his spine as he watched me regained consciousness. I looked around the now empty hawker centre. My severed hand was on the table. Beside the table, was the stall-holder.
He was stunned. His hands were shaking violently, still holding the chopper. He apologised profusely to me, eyes trying to avoid my burning glare.
Sitting at my balcony, I looked at my severed hand and sighed. My rash action has brought about a traumatic experience I will regret for the rest of my life.
A short excerpt from a good compo. Drool rolled down my chubby chin as I stared greedily at the rich, chunky chocolate cakes displayed prominently on the wooden shelf. The aroma of the freshly-baked chocolate cakes lingered into my nostrils. My sweaty palms pasted itself onto the spotless glass panel of the shelf. I eyed the mouth-watering chocolate cakes, yearning for a piece.
"Take your filthy hands off my shelf, you repulsive little tramp!" a loud shriek bellowed in the background. A lady impeccably dressed in her spotless uniform emerged from the kitchen. Her neatly-manicured fingers scratched my emaciated palms and removed it violently off the now smudged glass.
"Hey you irksome old swine, who do you think you are?" I asswerted in retaliation, trying my best to appear irrate. I rattled through my well-worn trousers, lots of mucky coins rained down my hole-filled pockets. "Give me a piece of cake." I snapped as I hastily grabbed the coins dispersed haphazardly on the cafe floor already muddied by my tattered, old shoe.
The lady gaped at me and retrieved a miniscule piece of cake from the shelf, disgruntled, "10 dollars," she declared flashing me a vicious smile.
"One cents, two cents... Nine dollars and eighty-five cents. I am still short of fifteen cents." I tallied my grimy coins for the third time and looked sheepishly at the floor. The lady intoherently looked at me and laughed maliciously...
So, just remember to leave around 10 minutes to go over your composition again and check for spelling/grammer mistakes. These mistakes can be avoided. Goodluck and all the best! :)

Dear Mr Lee,
Holiday Enrichment Programme
(What, Who, When, Where) I would like to thank you for giving me a chance to express my opinion on the holiday enrichment programme.
The Plus One Student Centre’s program is cheaper than the 3G Youth Training School’s program. The whole package cost $150 less and it is like receiving a 50% discount off the price. Cost is an issue because some of the students may not be able to afford the more expensive program. By choosing the cheaper program, we can make the program more economically viable for all students.
The Plus One Student Centre program takes only 5 days as compared to 7 days for the 3G Youth Training School’s program. It is difficult to plan programs during the holidays because of all the camps taking place. If the program takes a longer time to implement, we may find it difficult to fit into certain dates during the holidays. Furthermore, parents will be worried if their children is away for a long time.
The Plus One Student Centre focuses on digital art and computer animation skills training. With fast advancement of technology, it is getting more and more important for students to equip themselves with IT skills. However, the 3G Youth Training School program also provides them with an opportunity to build their communication skills. The program should also be fun because the students can take part in drama classes. In addition, it is good to improve students’ communication skills so that the students will be able to do better public presentations.
Both programs offer interesting outdoor activities. The Plus One Student Centre’s program builds up the adventurous spirit in students through water survival skills and trekking in Pulau Ubin. However, the 3G Youth Training School’s program can develop the character of the students through community service at St Joesph Home for the Aged.
I think learning life skills are more relevant to students than study skills. Students are always stressed during exams. Students may not know how to manage conflicts with their friends. So it is good that the Plus One Student Centre offers talks to students on how to deal with that. For the other program on study skills, I feel we have done enough during our assembly program.
In conclusion, I hope that you will choose the Plus One Student Centre’s program because it is cheaper and offers a more interesting and relevant program to students.

Population { Population growth & distribution }
Population growth: the increase in the number of people in a particular area Trend of World Population Growth: the changes in the growth in world population over a specified period Population Explosion: Rapid increase in population, a sudden increase
The number of people living in a certain area would always change in amount. However, there are different types of changes, mainly, there are 2 types of changes: -- Positive change -- Negative change
If there were no change, we call it 'Zero Population Growth'.
How is the world population distributed? -- Population distribution : how the population is distributed or spread out over an area ----- Distribution of the world population is uneven, some are densely populated (Overcrowded), some are sparsely populated ( Few People )
-- Population density: the number of people in one unit area of land ( E.g. km2) ----- Calculated like this:
Basically, just take the number of people divided by the area (in km2)
-- Places can be classified into three groups according to their population density: ----- Densely populated (High population density - over 200 persons per km2) ----- Moderately populated (Modreate population density - 10 to 200 persons per km2) ----- Sparsely populated (Low population density - under 10 persons per km2)
We have covered on simplifiying and factorisation in th previous post, so for this post, we are doing solving equations. It is difficult to type out the explanations, hence, I have added this video:
Solving equations would require both factorisation and simplification, so before you 'confuse' yourself with this solving chapter, you should review the previous post and refresh your memory. Also, when you expand, do be careful and do not make any mistake. Once there is a mistake, the whole thing from then on will be wrong. So, do be careful and also, use the few algebraic rules.
Thankyou!

Chapter TWO: Eating for Health - Explain obesity and its related health risks - Describe the effects of excessive intake of sugar, cholesterol and salt - Describe the effects of insufficient intake of dietary fibre, water, iron and calcium - Assess how an unhealthy diet can lead to certain cancers - Discuss two eating disorders - anorexia nervosa and bulimia nervosa
Obesity: Excessive accumulation of fats in body - Occurs when... -- Excessive intake of high-calorie food that have a high amount of fats and sugar -- Lifestyle with little or no physical exercise -- Excessive calories that the body does not need are stored in the body as fats, thus leading to obesity
Obese people have a greater risk of developing diseases such as diabetes, cancer and cardiovascular diseases (Disease that affects the heart and blood vessels) such as coronary heart disease, hypertension and stroke (A condition in which the brain loses some or all of its functions when the flow of blood to it is blocked).
:: Effects of excessive intake of sugar, cholesterol and salt :: Coronary Heart Disease ~ Cholesterol: A waxy substance found in food from animal sources (E.g. Egg Yolk) - Too much cholesterol in our diet can lead to coronary heart disease, which then lead to heart attack Here is a video to let you understand better:
As you can see, the excess cholesterol in blood causes a build-up of fatty deposits in the coronary arteries. These fatty deposits block the blood flow to the heart muscles and damage them. - Damaged muscles CANNOT be repaired - Eventually, the damaged heart muscles may stop pumping and cause a heart attack
Hypertension ~ - Caused by excessive intake of salt / sodium - Also can cause high blood pressure Here are some examples of food high in sodium:
Salt or sodium is usually 'hidden', or masked by other flavours. Most processed or preserved food contain a lot of 'hidden' salt or sodium. Be aware of food with 'hidden' salt. You should avoid or eat less of them.
Diabetes ~ - Usually said to have 'sugar in the urine' or 'sweet urine'. - Insulin is usually absent or not used properly by the body in a diabetic person - Hence, glucose cannot be converted into energy properly and remains in the blood - Too much glucose in the lood causes frequent urination, blurred vision, weight loss and tiredness - Some excess glucose is passed out of the body through urination
- Lower the risk of getting diabetes by maintaining a healthy weight through a balanced diet - And adequate exercise - Consume lesser food that is high in sugar
Tooth Decay and Gum Disease ~ - Caused by excessive intake of sugary food - Sweet and sticky food combine with bacteria in the mouth to form an invisible layer called plaque on our teeth ... - Tooth Decay :: -- Cavities formed on a tooth can cause pain and infection -- Left untreated, the tooth may need to be extracted - Gum Disease :: -- Bacteria present in plaque infect gums, making them sore and swollen -- Infected gums are painful and bleed easily -- Left untreated, the teeth may even become lose and fall out
:: Effects of insufficient intake of dietary fibre, water, iron and calcium ::
Constipation ~ - Insufficient intake of dietary fibre and water results in dry and hard faeces - Move very slowly through large intestine and require a lot of effort to be expelled from the body, causing constipation - Here are the steps that lead to constipation: #001 Waste products enter the large intestines from the small intestines #002 Water is extracted from the waste products for use by the body #003 More water is extracted as the waste products move through the larget intestines #004 Normal faeces are soft and semi-moist. These are easily expelled from the body. #005 Constipation occurs when there is insufficient fluids and dietary fibre in the diet and the faeces are hard and dry. Difficult to pass out from the body. - Prevent constipation by drinking more water and eating more fruits and vegetables (High in dietary fibre)
Anaemia ~ - Lack of iron, resulting in fewer red blood cells being produced and less oxygen being carried around the body - Anaemic person would often feel weak and tired - Prevent anaemia by eating food rich in iron such as liver, red meat, egg yolk and dark green vegetables
Osteoporosis ~ - Calcium builds strong bones and teeth - Insufficient intake of calcium over a long period of time - People who suffers from osteoporosis have bones who lose density and become brittle - More common in elderly than young people - Reduce risk of osteoporosis by consuming iron-rich food, like tofu, ikan bilis, milk and other diary products
This is a picture of a comparison of a normal bone and an osteoporotic bone.
:: Cancer :: - A general term for diseases in which abnormal cells in the body multiply out of control - Affects the proper functioning of organs in the body - Many chemicals used to make processed food are thought to be carcinogenic/cancer-causing (E.g. Smoked meat, ham, luncheon meat, salted fish and pickled vegetables) - Some cancers are linked to certain diets.. -- Stomach canter: Diet high in preserved and smoked food -- Colorectal cancer: Diet high in saturated fat, meat and alcohol, and low in dietary fibre
:: Eating Disorders :: - An unnatural obsession with food, weight and body image - Often thought to occur only amongst females, but males can have them too
Anorexia Nervosa ~ - Often called the 'slimming disease' - Have an unbalanced self-image of themselves and low self-esteem - May think they are overweight despite being dangerously thin - May starve themselves and exercise excessively - Warning signs include:: -- Extreme Weight Loss -- Menstruation stops -- Depressed and irrtable -- Problems coping with stress - If left untreated, can cause lasting damage to organs such as kidneys and reproductive organs - That anorexic person may eventualy starve to death
An anorexic Model.
Bulimia nervosa ~ - Have low self-exteem, linked to their body image - Bulimics binge or eat large amounts of food in a short period of time, then they get rid of the food they eat by purging - Bulimics purge by making themselves vomit or by using laxatives (Medicines to get rid of the waste from our body more easily) - May repeatedly binge, purge and over-exercise - Warning signs of bulimia nervosa.. -- Frequent trips to the bathroom, especially after meals -- Teary eyes and swollen cheeks -- Scraped knuckles from stikcing fingers down the throat to induce vomiting -- Stained teeth - May lead to tooth decay due to stomach acids being brought up during frequent vomiting - Somach weakened by repeated binging and excessive vomiting - May lead to heart failure, dehydration or even death

Weishi. P.S. I am unable to finish all the chapters of Home Economics, so hopefully you can study on your own, I sincerely apologise!
These are notes for home economics mid year. I do not know the notes for D&T, so unfortunately, I am unable to post it here online. Sorry! And for the girls, if you still do not know, the whole book will be tested in the paper on Thursday (14/5). So again, prepare writing materials and a piece of foolscap paper to jot down some important points or highlight them in your home economics textbook. Basically, there are two main categories under Home Economics. First is the 'Food Studies', which I will cover each chapter in different posts, and the 'Consumer Studies' in another post, so as to avoid confusion.
Chapter ONE: Planning Meals - Identify the factors to consider when planning meals - Explain the specific factors to consider when planning meals for children, teenagers and the elderly
Factors to consider when planning meals ~ = Nutritional needs - May also depend on certain special conditions that a person may have (E.g. Allergies) - Vary according to age, gender, body size and level of physical activity Examples: --> Gender: Females tend to consume more iron-rich food as they need them to replenish the blood which they lose during menstruation --> Level of physical activity: A desk-bound person would need less nutrition as lesser energy is needed, as compared to that of a construction worker
= State of Health - We all need different amounts of certain nutrients depending on our health Examples: --> An anaemic person would need to eat more iron-rich food --> A person who suffers from osteoporosis would need to consume more food rich in calcium
= Availability of Ingredients - Some seasonal or imported food are difficult to obtain - These ingredients can be substitued with those that are more readily available
= Budget for the food - Nutritious meal need not be expensive - Choose affordable ingredients
= Time Needed - Plan a meal that would not take long to cook if you only have a short time to spare - Remember to think about the preparation and cooking time before starting to cook the meal - Plan according to the number of people you are cooking for
= Religious and moral beliefs - Some have special dietary restrictions due to religious or moral beliefs Examples: --> Hindus do not eat beef for religious reasons --> Vegetarians do not eat meat for moral reasons
= Personal Preferences - Different people react differently to the same food - Some may like this, but others dislike the same food - Often choose food that we are more familiar with
= Culinary skills - Choose a simpler dish if you do not have the skills to prepare a difficult one
= Variety in the meal - Different colours, textures and flavours would make the meal more attractive and appetising - Different methods can be used for different types of dishes
Planning meals across the ages ~ - Nutritional needs change as we develop and grow - Plan meals based on the age groups of the consumers
= 13 - 18 years old (Teenagers) - Are at a stage of rapid growth - Often very active - Require nutrients for growth and development and to provide them with sufficient energy - Also have a higher energy requirement than children as they have bigger body frames -- Meals planned for teenagers should include plenty of water, fresh fruits and vegetables in order to prevent constipation and reduce spots and acne: - Drink plenty of water - Develop strong bones and teeth: food that is rich in calcium, phosphorous and vitamin D - Dietary fibre: Fresh fruits and vegetables - Provide sufficient energy: Consume carboyhydrates - Proper growth and development: Protein-rich food - Provide iron - rich food such as lean meat and dark green vegetables (Especially girls who are experiencing menstruation)
= 60 years and above (Elderly) - Have stopped growing physically and tend to be less active - Hence, their intake of energy-giving food should be reduced - Sill need a variety of nutrients in sufficient amounts for good health - Bodily functions slow down as they age (Slower bowel movement, difficulty in chewing) - Sense of smell and taste may not be as good as before -- Meals should be easy to chew and digest, stimulate poor appetite and provide them with strength and immunity: - Eat food with plenty of dietary fibre, drink lots of water and consume more soft fruits and cooked vegetables: Avoid constipation - Provide calcium and vitamin D-rich food such as milk and dairy products: Elderly are more prone to loss of bone density - Plan meals with less fats, oils, sugar and salt: Help reduce risk of diet-related diseases - Serve interesting variety of food and meals in small portions: to stimulate their appetite - Serve food that is soft and easy to digest: Cook dishes by boiling, steaming or stewing
Tools for healthy meal planning ~ - Help plan and choose recipes that are healthier for various age groups - Includes: Healthy Diet Pyramid, Dietary Guidelines for Children and Teenagers, Recommended Dietary allowance & Food composition table
Healthy Diet Pyramid.
Recommended Dietary Allowance: Shows the amount of various nutrients that we should consume each day. Food composition table: Shows the amount of various nutrients available in each type of food.
I hope that you will be able to read and study this in time. If you have any queries or comments, feel free to tag at the tagboard or email me at merlion0512@hotmail.com Thankyou!
Tuesday, May 12, 2009 - [ Literature: 'Kopitiam' ]
This is the post for literature. Literature examination is tomorrow, so hopefully, you have enough time to study. So anyway, literature is all about PEEE. With it, you can surely pass. Not going to the washroom to PEE, but the PEEE.
P: Point - Your main topic sentence E: Evidence - Your proof from the poem / play E: Explain - Explain what the proof has proven E: Elaborate - Elaborate with more specific details
So that is the PEEE!
Other than the PEEE, you also need to know the various poetic devices. These poetic devices are common in poems and you must remember them. Here are the poetic devices:
- Simile Comparing 2 objects /subjects together using 'as' or 'like' Examples: As hot as the sun, she ran like a gazelle
- Metaphor Direct comparison in which one object is described as being something else Examples: She is a pig, the pavement was a ribbon of moonlight
- Personification Giving a non-living thing human characteristics Examples: The storm attacked me, the plant creeped along the gates
- Alliteration Repeating the cosonant sounds af the beginning of words Example: Ages and ages.
- Hyperbole A gross exageration. Example: The boy was as fast as a jet.
- Repetition Repeating the same words in a same poem, can be in different stanzas Example: 'Two roads diverged in a wood" appeared in both stanza 1 and 4.
- Symbolism A word or object that stands for another word or object. A symbol of another object, usually with similar characteristics. Example: The road symbolises the path in life.
So these are the few poetic devices that will most probably be tested, especially simile, metaphor, alliteration and personification. Now, here is the information that we learnt in kopitiam, the seen play that will be tested.
CONFLICT The struggle between the opposing forces on which the action in a work of literature depends. 4 types of main conflict: Man VS Man, Man VS Environment, Man VS Society & Man VS Himself
Conflict in the play: #01 Man VS Man: Grandpa versus Jiacai (Have different values) #02 Man VS Society: Grandpa's old values versus the modern values
Why does the conflict between Grandpa and Jiacai occur? Generation gap - Growing up in different eras Grandpa refuses to change his thinking, while Jiacai is changing with modernisation.
What is each character's motivation for his beliefs? Jiacai: Must change to survive Grandpa: Has gone through hardship and survived, so does not agree with Jiacai's thought.
Flashback - Questions to ponder #01 Which is the main plot: Present or the flashback? Why do you think that? - The present. - The flashack is just a series of stories from unnamed characters - The present is where the main characters are and where the main conflict is
#02 Why does the author, Kuo Pao, insert a flashback in the midst of Grandpa and Jiacai's conversation? What purpose does the flashback serve? - To elicit pity for Grandpa - To make grandpa's story more credible / realistic - To relate grandpa's hardship -> reinforces the contrast between Jiacai and grandpa - To show that Grandpa's not the only one who feels this way
#03 Why does the author choose to have the customers remain nameless? What purpose does the lack of name serve? - So the stories can be applied to anyone, far-reading impacts, can be universal - To focus on a specific character
Contrast between Grandpa and Jiacai! How different are Grandpa and Jiacai in terms of their perceptions or attitudes towards..
Games ~ Grandpa : Kids back then played with balls, marbles and kites. Were contented with simple games. Evidence: "When I was young, you bought me rubber balls to play, or goli, or layang." (Jiacai, line 16)
Jiacai: Kids nowadays play video games. More demanding in their choice of entertainment. Evidence: "But kids how start playing video games before they even get to primary school." (Jiacai, line 18)
Storytelling ~ Grandpa: Prefers to get his stories from the word of mouth. Appreciates the engagement of human interaction. Evidence: " He loved telling stories, all the time teaching me the Confucian virtues." (Grandpa, line 6)
Jiacai: Gets the stories from Tv, film and radio. More technologically advanced, IT savvy. Evidence: " And of course when you've got TV, film and radio you don't have any need for storytelling..." (Jiacai, line 21)
Food ~ Grandpa: Wants to retain the essence of his food to make sure it is unique, special and authentic. Process is more important to him. He is patient. Evidence: " We bake our own kopi beans, we grind our own powder, we make every cup special and they all taste special" (Grandpa, line 31)
Jiacai: People now don't care about the essence of food. Modern people look for expediency, efficiency and speed. He does not care about the process and is impatient. Evidence: " People today all want to go to a cafe or fastfood centre. They don't want to go to a kopitiam anymore" (Jiacai, line 25)
Business Philosophy ~ how they run their business Grandpa: Kopitiam allowed him to save cent-by-cent and send Jiacai abroad. Allowed him to be frugal, does not take big risks to save up. Refuses to change. Evidence: " From 1936 ... Almost 50 years now ... we saved from every cup, every cent, we have saved everything we have now! " (Grandpa, line 43)
Jiacai: Grandpa's kopitiam needs to change into a coffee house because that is what people want nowadays. Expansion - letting the money grow by creating more business opportunities. Wants to change according to modern times. Evidence: " Baba's good friend, Uncle Di Ge - now, that man's got a good head. He saw what was coming and decided to change as soon as he realised the need to change." (Jiacai, line 56)
Home ~ Grandpa: We must all remain loyal to our motherland. Evidence: "
Jiacai: If you suffer hardships at home, is it not right to move? Evidence: " Yes, and she would rather fall sick, and eventually died there! Right? But is it worth it?" (Jiacai, line 88)
So these are the important points that you need to know for the examination, and remember the poetic devices and PEEE!
If you have any queries or questions, feel free to tag at the tagboard or email me at merlion0512@hotmail.com Thankyou! And credits to Caroline who helped me with these notes!
Here are some guidelines on answering a good compare & contrast question, remember to always answer in complete sentences. And remember to grab a pen and a piece of paper to jot down the notes.
Compare and contrast simply means to look for the similarities and/or differences between two sources. To do this, you need to refer to some common criteria:
- Source Type
- Provenance
- Content
Example sources ~
Source A:
"Joe is always helping me when I am in trouble. When I am absent he takes notes in class for me." - Joe's friend and classmate.
Source B:
"Even when Joe lends us his things, he will do it very reluctantly. Moreover, whenever he helps someone, he always asks for something in return." - Joe's enemy and classmate.
Question type #01: In what ways are the two sources similar? / How are the two sources similar?
What you need to do #01: Similarities ONLY
(Give 2 similarities in content, supported with evidence from both sources)
Question type #02: In what ways are the two sources different? / How are the two sources different? / How do the two sources differ?
What you need to do #02: Differences ONLY
(Give 2 differences in content, supported with evidence from both sources)
Question type #03: How similar are the two sources? / How are the two sources similar? / To what extent are the two sources similar?
What you need to do #03: Similarities AND Differences
(Give 1 similarity and 1 difference in content, supported with evidence from both sources)
Question type #04: How different are the two sources? / How far are the two sources different? / To what extent are the two sources different?
What you need to do #04: Similarities AND Differences
(Give 1 similarity and 1 difference in content, supported with evidence from both sources)

These are the summarised notes of History, so if you need to take down some notes or some stuffs, I would suggest you taking out a pen and a foolscap pad.
Please note that the blog is protected and you are unable to just copy and paste down the notes.
Teehee!
So anyway, this post will be on the first chapter that will be tested, which is:
- Chapter ONE: Was there Singapore before 1819
So, let us begin. I will only post the points that are important and those that Mr Edgerton (History teacher) said that would be tested.
Chapter ONE = Was there Singapore Before 1819?
With the help of Artifacts and Written evidence, Singapore was known to exist as a fishing village before the 1819.
It was then known as Temasek.
Let us look further into the two types of evidence.
Artifacts
Artifacts are human-made objects, such as a tool, weapon or ornament, especially those of archaelogical or historical interest. There are 2 important and main artifacts which proved that Singapore existed before the 1819.
1. Singapore Stone
- One of the earliest artifacts left behind in Singapore
- A large rock measuring 3 meters wide and high
- Found 150 years ago, located at the mouth of Singapore river
- Some inscriptions were seen on the stone, but historians could not decipher it, they believed that writing dates back to the 12th or 13th century.
- Shows that there were people who lived in the ancient times could read and write, but in an unfamiliar language, unknown to use today
- Tells us that Singapore, better known as Temasek then, existed a long time ago
2. Jewellery, Porcelain, stoneware and earthern ware
- Found at Fort Canning Park
- Dated the 14th Century
- Believed to have been brought by visitors/traders from Majapahit as they were similarly designed to those produced by the Majapahit Empire
- Blue & White porcelain pieces reflected that there were ancient Chinese traders who traded in Singapore
Written Evidence
These are historical records such as maps, minutes of meetings, official court documents etc. It helps us to better understand things that happened in the past.
1. The Melayu Sejerah
- Proved that Singapore was called 'Temasek' in the 13th and 14th centuries
- Was believed to be founded by a Malay ruler from Sumatra called Sang Nila Utama, who renamed 'Temasek' into 'Singapura', meaning Lion City
- Singapore was said to be often attacked by its stronger neighbours like the Siamese and Javanese who both wanted to make it part of their empire
- A fort was then built to ward off these attacks, at Fort Canning Hill
- Was dangerous to trade in Singapore due to the many pirate attacks
2. Chinese Records
- Earliest written records on Singapore was by a Chinese traveler called Wang Dayuan, who visited Singapore in the 14th century
- Recored that Singapore was a great and famous place with many foreigners visiting
- Singapore then was a trading centre where Chinese traders brought valuable goods to sell
- Proved to have some Chinese living on the island who dressed like the local people
Archaeologists
- Tries to find artefacts that existed long time ago by digging anywhere that was appropriate
Decline of Singapore
- A Malay chief named Parameswara murdered the local ruler and made himself the new ruler of Singapore
- Parameswara was soon driven away, Singapore lost its important place
- He fled from Singapore and found a new city at Malacca, which became the biggest trading city in Southeast Asia

These are the topics tested for literature, There will be 2 parts, Unseen poetry and Seen poetry. The details will be further elaborated in another post.
Unseen poetry ~ = Peotic devices: Metaphor, Hyperbole, Alliteration, Simile, Personification, Repetition = Understanding the theme of the poem: Main point = Characterisation: Interpreting the characteristics of the characters
Seen poetry ~ 'Kopitiam' = Conflicts: 4 types = Flashback: Purpose / Unnamed customers = Why did they each believe in their own beliefs? = Differences between Grandpa & Jiacai
Any errors or queries, please leave a message in the tagboard or email me at: merlion0512@hotmail.com Thankyou!

Sunday, April 12, 2009 - [ Mathematics : MYE Topics ]
These are the topics that will be tested in the Mid Year Examinations, if you want to study them beforehand... Of course I will try my best to post all the details on this blog before mid year, but I may not finish everything, so STUDY BEFOREHAND!
= Similarity & Congruency = Percentage, ratio & rate = Direct & Indirect proportion
= Construction of triangles & Quadrileterals - Perpendiculor Bisectors - Parallel Lines - Angles Bisectors
= Algebra - Simplification / Expansion (Refer to April 6,2009) - Factorisation - Fractions ('+', '-', '/', 'x') - Changing of Subject of Formula
= Prime factorisation - Highest common factors - Lowest common multiple
So, these are the topics that will be tested for mid year, so do study! And dont say you didnt know the topic, they are all here! =P All the best! Jiayous!
This post will cover what will be tested during the Mid Year examination, for chemistry. Basically, it will be mainly tested on acid and alkali. So, everything will be here, and be prepared to take down notes, if you dont want to refer to your own notes.. =X
Defination of acid: A substance that produces hydrogen ions (H+) as the only positive ions when it is dissolved in water Physical Characteristics of acid: --- pH <7>Defination of alkali: A substance that produces hydroxide ions (OH-) as the only negative ions when it is dissolved in water Physical Characteristics of alkali: --- pH >7 --- Bitter taste --- Caustic (Burning sensation, only for very concentrated ones) --- Soapy feeling --- Turns red litmus paper blue --- Conducts electricity due to presence of mobile ions
Testing for various gases: ---- Ammonia (NH3): Test with damp/moist red litmus paper -- Observation: Colourless, pungent gas turns damp red litmus paper blue ---- Carbon Dioxide (CO2): Test by bubbling gas into limewater (Calcium hydroxide) -- Observation: Colourless, odourless gas forms a white precipitate with limewater (Calcium hydroxide) ---- Chlorine (Cl2): Test with damp/moist blue litmus paper -- Observation: Yellowish, pungent gas turns damp blue litmus paper red and then bleaches ---- Hydrogen (H2): Test by inserting a lighted/burning splint into the test tube -- Observation: Splint extinguishes with a "Pop" sound ---- Oxygen (O2): Test by inserting a glowing splint into the test tube -- Observation: Colourless, odourless gas relights a glowing splint ---- Sulfer Dioxide (SO2): Test by bubbling gas into - Aqueous potassium dichromate (VI) or Acidified potassium manganate (VII) -- Observation: Colourless, pungent gas turns - 1. Aqueous potassium dichromate (VI) from orange to green /or/ 2. Acidified potassium manganate (VII) from purple to colourless
Reaction of acids with metal carbonates: #001: Effervescence occurs. #002: Carbon Dioxide gas is produced. Word Equation: Acid + Carbonate = Salt + Water + Carbon Dioxide Example: Hydrochloric acid + Zinc carbonate = Zinc chloride + Water + Carbon Dioxide
Reaction of acids withmetals: #001: Effervescence occurs. #002: Hydrogen gas is produced. Word Equation: Acid + Metal = Salt + Hydrogen Example: Nitric Acid + Iron = Iron Nitrate + Hydrogen
Reaction of acids with alkali: #001: No effervescence occurs. #002: Nothing is produced. Word Equation: Acid + Alkali = Salt + Water Example: Sulfuric Acid + Calcium Hydroxide = Calcium Sulfate + Water
Good Natural Indicators: Red Cabbage & Beetroot
Indicators: - Methyl Orange --- pH range: Below 3.1 = Red, Above 4.4 = Yellow --- Turns Acid to Red, and Alkali to Yellow --- Chemical name: p-dimethylamino-azobenzensulfonic acid, C14H35N3O3S --- Suitable to be used for acidic solution - pH paper --- pH range: 1 to 14 --- Usually used to test pH value of soils and urine
- Universal Indicator --- Original colour: Dark Green (Very concentrated) --- Turns Acid to red, orange or yellow/turns Alkali to blue or purple (Based on the level of concentration) - Phenolphthalein --- Original colour: Colourless --- Cannot be used to distinguish acid from water --- Turns Alkali to Pink, no colour change in Acid --- In solutions containing pH below zero, phenolpthalein turns right orange in colour --- In solutions that are very alkaline or basic, phenolphthalein turns purple in colour

I am Weishi from Singapore. And currently studying! :)
Graduating soon, so while im busy, i'll upload notes once im free.
Firstly, I warmly welcome you to the best online learning site! Basically, I thought of this idea through the many learning portals.
I thought that it would be troublesome, and the learning portals would only allow certain students to get in.
So I decided, why not let the whole world learn online together?
It will SAVE money on buying assessment/guide books, BUILD a strong foundation for the various subjects, and let the whole world ENJOY learning together.
If you want any particular subjects or level to be published on this website, just request and I will try my best. All the best and keep coming!
