Warm water from the bath evaporated into warm water vapour. The water vapour then condensed onto the cool surface of the glass door, causing the mist.
2. Timmy carried out an experiment to find out how different surfaces affect the bouncing height of a tennis ball when dropped from a same height. He used a plastic surface and a plasticine surface.
a) Which of the 2 surfaces will be the bouncing height be higher?
Plastic surface
b) Explain why the surface you have chosen in (a) cause the bouncing height to be higher.
A harder surface would not absorb as much of the impact of the ball as compared to a softer surface. Plastic is a harder surface and this allows the ball to be able to bounce of it higher as compared to plasticine which will absorb more of the impact.
c) Name one OTHER variable to be kept the same for the experiment to be a fair test.
1. Force used to drop the balls.
2. Size of tennis ball / weight of tennis ball

Answers for Week 6
Dear all,
Here are the answers for the week. My apologies for the late post.
English
Q1. His dog will die unless he takes good care of it.
Note: After the word 'unless', it is always followed directly with a positive statement.
Q2. Peter asked May if/whether she would be able to make it for the party the following/next day.
Note: Look at the tense of the verb outside the conversation/speech first. If it is past tense, we have to change the tenses within the speech (present --> past, past --> past perfect, past perfect would remain as it is). Next, look at the punctuation mark. If it is a '?", we have to make sure that in our answer, the subject comes first followed by the verb(s).
Q3. The boys insisted on playing on the field however heavy the rain was.
Note: 'however' has the same meaning as no matter how. After the word 'however', it is accompanied by the adjective - noun - verb.
Q4. The old lady tripped and fell down due to the worker's negligence.
Note: After the words 'due to', it is followed by the subject and then the noun. In this case here, you have to change the adjective in the original sentence to its noun form, e.g (happy --> happiness, sad --> sadness, disappointed --> disappointment) In this case here, negligent as an adjective is changed to negligence.
Q5. With ease, the puppy crawled through the tiny hole.
Note: Somewhat similar to the Q4, after the word 'with', it is followed by the noun. In this case here, you have to change the adjective or adverb in the original sentence to a noun. 'easily' is changed to 'ease'.
Science
Q1. The source of energy for the toy car is the batteries (contains chemical energy).
Q2. Chemical energy --> Kinetic energy + Sound energy + Heat energy

Q1. The source of energy for the toy car is the batteries (contains chemical energy).
Q2. Chemical energy --> Kinetic energy + Sound energy + Heat energy
Topic: Heat
Processes: Expansion and contraction
Concept: Heat expands objects while cool air contracts objects.
Answer:
The gaps allow space for expansion of the metal rails during a hot gap to prevent the metal rails from cracking. During a cool day, the gap then allows space for contraction.
Q3. Topic: Heat
Processes: Absorbing and Radiating of Heat
Concept: Dark coloured objects absorb heat much better than lighter coloured/shiny objects.
Answer:
(a) Dark coloured objects absborb heat much better than lighter coloured objects. As a result, the black coloured box absorbs more heat than the shiny box and the heat is conducted through the box to melt the ice at a faster rate than the ice in the shiny box.
(b) Size of the box, number of ice, size of the ice, Place where the box is put at

The Cell X absorbed more water than its cell membrane could hold or The cell does not have a cell wall to contain the water.
Explanation: The cell wall is an important part of the plant cell to hold the cell in place and protect the cell from the outside. The cell membrane of both cells are semi-permeable (only allows some items to pass in and out through the cell) and without a cell wall to hold the cell in place, cell X will burst when too much water is absorbed. On the other hand, the cell wall for Y protects the cell.
Q2.
Answer:
The cell wall of Cell Y supported the cell structure and was strong enough to prevent it from bursting.
Topic: Magnets
Concept: Magnetic objects can be magnetized by the stroking method. Like poles attract, unlike poles repel. A magnet has a North pole and a South pole on each opposite end.
Answer:
Part (A) i and ii
C: South Pole
D: North Pole
Part (B)
Both of the poles of steel bar XY would be like poles (South and South). A magnet has two unlike poles in which both the unlike poles of the magnet has the ability to attract and repel other magnets. In this instance, both the ends are like poles and it does not fulfil the characteristic of a magnet.
Topic: Heat (Expansion and Contraction)
Concept: Heat expands items, Cool air contracts items.
Answer: The metal bridge will crack and might collapse. The gaps allow for the metal structure to expand during a very hot day due to the heat and contract during a cool day. If there is no gaps for the metal structure to expand, it will be compressed and the structure will push against each other, resulting in a crack and collapse of the bridge.
Explanation: There are two parts to the answer. The first part is an observation of what happens to the bridge when there are no gaps on a very hot day. The second part involves the use of concepts and key words to explain the answer.
The gaps allow for expansion and contraction (not just expansion only) during hot and cool days. This gives space for the processes to take place. Without the gaps, the structure will push against each other and will crack.
Here are the answers.

Answers for week 3
Dear all,
Here are the answers for this week's questions.
Here are the answers for this week's questions.
Q6. (1) complete
Explanation: made (past tense) Susan (Noun) [if a verb is used here, it is used in the base form, meaning present tense and plural form]
Q7. (2) herself
Explanation: Keywords to highlight are "who completed the project". This is a tricky question. We are finding out who completed the project and in this case, it is Miss Chew, a female and hence the pronoun, 'herself'.
Q8. (4) were
Explanation: The rule for 'either...or' and 'neither...nor' questions is to always look at the second subject and in this case, it is his friends (plural). Now, let us take a look at the tense to use and the word 'rang' suggests that it is in the past tense thus, the answer should be in the plural form but past tense.
Q9. (3) does he
Explanation: The question is phrased in a questioning form, thus the two parts of the sentences should be opposite in meaning to each other. In this case, you must read very carefully. The first part 'hardly ever goes to parties' means that he does not usually go to parties so the second part of the sentence should be opposite of 'does not'.
Q10. (4) flown
Explanation: The keywords here are 'ever' and 'before' which would suggest that the perfect tense should be used as it has already taken place.
Fly (present tense) Flew (past tense) Flown (perfect tense)
Q16. (2) infested
Explanation:
infested is used on insects or animals ; meaning to be present in large numbers to cause damage and harm
invasion is usually used on people, e.g invaded by enemies, invaded by the French army.
Q17. (4) fell through
Explanation:
fell through means not completed and stopped
fell out means to have a disagreement and stop interacting with someone
Q18. (2) yields
Explanation: This question is of a higher difficulty level. The key word you have to look at is 'harvest'.
yield is to give forth or produce by a natural process or in return for cultivation. e.g This farm yields enough fruit to meet all our needs.
reaps is to get as a return, recompense, or result: to reap large profits.
Q19. (3) accessible
Explanation: The key words are "offshore islands" and "motorboat". As such, it is talking about travelling and whether the place itself is accessible.
Q20. (3) subsided
Explanation: The key word here is 'flood' and we often talk about a flood subsiding.
Subside means to sink to a low or lower level.
I realised I have forgotten to post the questions for this. I will do so tomorrow. My apologies.

Answers for Week 2
English Synthesis and Transformation:
Q1. Helen prefers playing computer games to reading.
Ans: Helen would rather play computer games than read.
- Explanation:
Prefer (verb --> continuous form) to (verb --> continuous form)
example: Prefer walking to running, prefer taking the bus to riding on the train
Rather (verb --> any form except continuous form) than (verb --> any form except continuous form)
example: Rather smile than frown, rather walk home than take a lift from him.
Read this link if you need more details on prefer __ to ___ and rather ___ than ____ rules.
Q2. We did not believe that Amy said that.
Ans: None of us believed that Amy said that.
- Explanation:
In this case here, the tense of the verb is in past tense. If we are to use the present tense, none is usually accompanied by a singular tense, e.g none of us is going, none of us believes
Q3. He did not keep his promise. It upset me.
Ans: The fact that he did not keep his promise upset me.
- Explanation:
The past tense and participle tense of upset is still upset.
Q4. The toy is expensive. It is a waste of money to buy it.
Ans: To buy such an expensive toy is a waste of money.
Q5. Victor asked his brother, "Have you decided what gift to buy for James?"
Ans: Victor asked his brother if/whether he had decided what gift to buy for James.
- Explanation:
Remember the rules for direct to indirect speech:
- Look at the tense of the verb outside of the speech. If it is in present tense, you do not need to change the tense of the verb in the direct speech.
- If it is in the past tense, you have to change the tenses in the direct speech, present to past tense, past tense to past participle tense.
- If the speech is a question, when you change from direct to indirect speech, the subject comes first followed by the verb, e.g 'Have you decided?' --> 'He had decided.'
Science Answers
Answer for 2(a)
She was trying to make a magnet by the electrical/electromagnetism method.
Explanation:
By passing electricity through a magnetic material, it could be turned into a magnet.
Answer for 2(b)
She did not coil the wire around the iron nail several times. She needs to coil the wire around the nail about 20 times.
Explanation:
The nail did not become magnetised because the wire had not been coiled several times around it. If she coils the wire several time around the nail, it will become an electromagnet and pick up the paper clips.
**To note:
A magnet cannot be attracted to a magnetic object. It is the magnetic object that is attracted to the magnet. Do take note of this when writing your answer.
Answer for 3(a)
A: South Pole
B: North Pole
Explanation:
The magnets stay afloat because the are repelling one another. As such, based on the concept that like poles repel and since the bottom of C is the South Pole, the top of C is the North Pole. Bottom of B should also be the North Pole. The top of B is thus the South Pole and the bottom of A is the South Pole.
Take out the centre/middle magnet, flip it over so that the North Pole is facing upwards and then place is back into the centre/middle position.
Explanation:
Based on the concept that unlike pole attract one another, we need to let the unlike poles of the magnet face one another. We can do that by changing the direction of the poles in the centre/middle. The centre magnet must be arranged so that its North pole faces upwards and South pole faces downwards. In this way, all the unlike poles of the magnet face one another and attraction between the poles take place.
Until next week, study hard!

Mr Nelson Ong

Answer for (a)
She would observe the drop of blue ink rising up the glass tube.
Explanation: Most matter expand when heated. When heat is supplied to the flask, it gains heat. The air in the flask also gets heated. This air expands, increases in volume and moves up the glass tube, pushing the drop of ink up the glass tube.
Answer for (b)
The drop of ink would move down the glass tube.
Explanation: When the flask is placed in ice water, the flask and air cool down, contract and decrease in volume. The drop of blue ink oves down the glass tube.
Answer for (c)
It shows hot air expands when heated and contracts when cooled.
Explanation: The concept here is showing expansion and contraction when heated and cooled respectively. The matter involved is air.
Answer:
1. Good conductors of heat:
