Bahagian ASection A
10 marksJawab semua soalan. Setiap soalan diikuti oleh empat pilihan jawapan, A, B, C dan D. Bulatkan satu jawapan yang betul.Answer all questions. Each question has four options, A, B, C and D. Circle one correct answer.
1
Question 1
Hakim menyiasat jarak yang dilalui oleh sebuah kereta mainan apabila ketinggian landasan diubah. Dia menaikkan landasan itu dengan buku. Jadual 1 menunjukkan keputusannya.
Apakah pemboleh ubah bergerak balas dalam penyiasatan ini?Hakim investigates the distance travelled by a toy car when the height of a ramp is changed. He raises the ramp with books. Table 1 shows his results. What is the responding variable in this investigation?
| Bilangan buku / Number of books | 1 | 2 | 3 |
|---|---|---|---|
| Jarak yang dilalui / Distance travelled (cm) | 40 | 75 | 110 |
Show answerHide answer
B
The responding variable is what we measure and what changes because of the manipulated variable. The number of books is the manipulated variable. The mass of the car and the type of floor are kept the same (constant variables). Textbook p. 6.

Question 2
Aina jatuh daripada basikal dan tulang lengan bawahnya patah. Lengannya menjadi bengkak kerana aliran darah di lengan itu terganggu. Dua sistem manakah yang terganggu?Aina falls off her bicycle and a bone in her forearm breaks. Her arm becomes swollen because the flow of blood in the arm is disturbed. Which two systems are disturbed?
Show answerHide answer
A
A broken bone disturbs the skeletal system. The swelling shows that blood flow, which belongs to the blood circulatory system, is disturbed too (textbook p. 37). The systems of the body depend on one another.

Question 3
Rajah 1 menunjukkan siratan makanan di sebuah terumbu karang. Semua landak laut di terumbu karang itu mati kerana penyakit. Apakah yang akan berlaku?Diagram 1 shows a food web on a coral reef. All the sea urchins on the reef die from a disease. What will happen?
Show answerHide answer
C
Only the sea urchin is eaten by the octopus, so the octopus loses its only food and its number will fall. The grouper can still eat parrotfish, so it still has food. Fewer animals eat the seaweed, so the seaweed does not decrease. The shark eats only the grouper, whose food has not gone.

Question 4
Tumbuhan X menggulung daunnya apabila cuaca panas dan musim kemarau supaya tidak banyak air hilang. Apakah tumbuhan X?Plant X rolls its leaves when the weather is hot and in the dry season so that it does not lose much water. What is plant X?
Show answerHide answer
D
The turmeric plant rolls its leaves in hot weather to prevent water loss (textbook p. 100). The casuarina has a flexible trunk and needle-shaped leaves to reduce the force of strong winds, the coconut has a flexible trunk and split leaves, and the durian has sharp thorns.
5
Question 5
Rajah 2 menunjukkan litar yang dibina oleh Rina. Dia menambah dua biji sel kering lagi dalam litar itu dan satu mentol baharu pada cabang baharu. Bagaimanakah kecerahan mentol P, Q dan R berbanding dengan sebelum itu?Diagram 2 shows a circuit that Rina builds. She adds two more dry cells to the circuit and a new bulb on a new branch. How does the brightness of bulbs P, Q and R compare with before?
Show answerHide answer
C
More dry cells make the bulbs brighter in a parallel circuit. Each bulb is on its own branch, so adding a bulb in a new branch does not make the other bulbs dimmer (textbook pp. 127–128).

Question 6
Rajah 3 menunjukkan seketul batu pada suhu 90 °C dimasukkan ke dalam sebikar air pada suhu 20 °C. Tiada haba hilang ke persekitaran. Selepas beberapa lama, suhu batu dan suhu air menjadi sama. Apakah suhu yang mungkin?Diagram 3 shows a stone at 90 °C put into a beaker of water at 20 °C. No heat is lost to the surroundings. After some time, the temperature of the stone and the temperature of the water become the same. What could this temperature be?
Show answerHide answer
B
Heat flows from the hotter stone to the cooler water. The stone loses heat, so it falls below 90 °C. The water gains heat, so it rises above 20 °C. They stop changing when both have the same temperature, which must be between 20 °C and 90 °C. Only 55 °C is.

Question 7
Jadual 2 menunjukkan dua objek besi di taman permainan sekolah. Apakah cara paling sesuai untuk mencegah X dan Y daripada berkarat?
Table 2 shows two iron objects in the school playground. What is the most suitable way to stop X and Y from rusting?
| Objek / Object | Keterangan / Description |
|---|---|
| X | Rantai buaian yang sentiasa bergerak / A swing chain that keeps moving |
| Y | Pagar besi yang tidak bergerak / An iron fence that does not move |
Show answerHide answer
D
Oil or grease suits moving parts such as chains. Paint covers the surface of a fence or gate (textbook p. 170). Paint on a moving chain would peel off.
8
Question 8
Jadual 3 menunjukkan sifat tiga bahan, X, Y dan Z. Antara yang berikut, manakah yang benar?
Table 3 shows the properties of three substances, X, Y and Z. Which statement is correct?
| Bahan / Substance | Bentuk tetap? / Fixed shape? | Isi padu tetap? / Fixed volume? |
|---|---|---|
| X | Ya / Yes | Ya / Yes |
| Y | Tidak / No | Ya / Yes |
| Z | Tidak / No | Tidak / No |
Show answerHide answer
A
A solid has a fixed shape and volume (X). A liquid has a fixed volume but no fixed shape (Y). A gas has neither (Z). A liquid is not fixed in shape, so Y is a liquid, not a gas; a fixed volume does not make Y a solid (textbook p. 180).

Question 9
Rajah 4 menunjukkan buruj yang dilihat oleh seorang petani di belahan bumi utara pada zaman dahulu, sebelum kalendar dicipta. Apakah yang diberitahu oleh buruj itu kepada petani?Diagram 4 shows a constellation that a farmer in the northern hemisphere saw long ago, before calendars were invented. What does the constellation tell the farmer?
Show answerHide answer
B
The seven-star pattern like a ladle is the Big Dipper. Farmers used it to know that the planting season had started (textbook p. 212). Orion shows the start of winter, and the Scorpion shows the harvesting season.
10
Question 10
Gerudi tangan digunakan untuk membuat lubang pada papan. Gerudi itu mempunyai baji, skru dan roda dan gandar. Antara yang berikut, yang manakah fungsi yang betul bagi mesin ringkas dalam gerudi tangan itu?A hand drill is used to make holes in a plank. The drill has a wedge, a screw and a wheel and axle. Which is the correct function of the simple machines in the hand drill?
Show answerHide answer
C
In a hand drill the wedge makes holes and the wheel and axle makes the handle easier to turn (textbook p. 221). The screw fastens parts.
