Question 1
Hana ingin mengetahui sama ada saiz kon kertas mempengaruhi masa yang diambil oleh kon itu untuk jatuh ke lantai. Antara yang berikut, yang manakah hipotesis yang sesuai?Hana wants to find out whether the size of a paper cone affects the time the cone takes to fall to the floor. Which is a suitable hypothesis?
Show answerHide answer
C
A hypothesis says how the manipulated variable (size of the cone) is related to the responding variable (time to fall), in the form 'the more ... the more ...' (textbook p. 9). A is the problem statement, B is the aim and D is a measurement.

Question 2
Selepas berlari dalam satu perlumbaan, jantung Zul berdenyut lebih laju. Mengapakah hal ini berlaku?After running in a race, Zul's heart beats faster. Why?
Show answerHide answer
B
The heart pumps blood, and the blood carries oxygen to the whole body (textbook p. 33). Running makes the muscles need more oxygen, so the heart pumps faster.

Jadual 1 / Table 1Table 1 shows the characteristics of four seeds or fruits, P, Q, R and S. Which seed or fruit is dispersed by water?
Show answerHide answer
A
A waxy skin and a husk with air cavities make a fruit float, like the coconut, so water carries it (textbook p. 105). P is dispersed by wind, Q sticks to animals and S is eaten by animals and humans.

Jadual 2 / Table 2Table 2 shows four circuits built with identical bulbs. In which circuit are the bulbs the brightest?
Show answerHide answer
D
More dry cells make the bulbs brighter, and the bulbs in a parallel circuit are brighter than in a series circuit because each branch receives the same electrical energy (textbook pp. 123–125). Circuit S is parallel and has two dry cells.

Question 6
Penutup logam sebuah balang kaca terlalu ketat untuk dibuka. Ibu menuangkan air panas ke atas penutup itu selama seminit dan penutup itu dapat dibuka dengan mudah. Mengapakah?The metal lid of a glass jar is too tight to open. Mother pours hot water over the lid for one minute and the lid can then be opened easily. Why?
Show answerHide answer
B
A solid expands when it gains heat (textbook p. 154). The lid gains heat from the hot water, expands and becomes loose. A solid does not become lighter when it is heated, it only becomes bigger.

Rajah 2Diagram 2
Show answerHide answer
A
Water vapour in the warm air touches the cold glass, loses heat and changes into drops of liquid water. This is condensation (textbook p. 187, like dew and a foggy mirror). Water cannot pass through glass.

Rajah 3Diagram 3
[2 marks](a)Tulis huruf simbol bagi (i) mentol, (ii) sel kering.Write the letter of the symbol for (i) a bulb, (ii) a dry cell.
Show answerHide answer
A bulb is a circle with a cross. A dry cell is one long thin line and one short thick line (textbook p. 120). P is an open switch and S is a closed switch.
Tick each point you got.
[2 marks](b)Tulis litar siri atau litar selari bagi setiap pernyataan. (i) Semua mentol padam apabila satu suis dibuka.

(ii) The electric current has more than one path to flow.
Show answerHide answer
A series circuit has one path, so an open switch stops the current everywhere. A parallel circuit has branches, so there is more than one path (textbook pp. 118–119).
