1. After a bath, Timmy realises that his glass door is very misty and he could not see through it. Explain what causes the mist on his glass door.

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
3. Height of surface

Science

Q1. A ball was placed on a 1metre high chair. Tom then push the ball forward and it landed onto the ground. 

a) Explain how the force exerted by Tom help push the ball forward and onto the floor.

Forces can cause a stationary object to move. When Tom pushes the ball forward, gravitational potential energy is converted to kinetic energy and the force pushes the ball forward and onto the floor.

b) It this force a pull or push?

Push

c) Complete the energy conversion.

Gravitational potential energy --> Kinetic energy --> Sound energy + Heat energy

d) As the ball gets lower, the amount of gravitational potential energy decreases while the amount of kinetic energy increases.

Q2. Ahmad put a glass cup of warm water in the open. He noticed X forming on the outer surface of the glass after some time.

a) What is X?

Water droplets

b) How is X formed?

'WCCW' acronym!

When the warm water vapour from the surrounding air touches the cool surface of the glass, it condenses into water droplets. 

c) If Ahmad wants to reduce the amount of X on the outer surface of the glass, what can he do?

1. He can put an object with a cooler surface at the top of the glass surrounding it.
2. He can increase the temperature of the glass so that it becomes warmer and less water vapour will condense on its warmer surface.

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

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
