1
Question 1
Sebatang lilin yang menyala memendek pada kadar yang sama. Jadual 1 menunjukkan tinggi lilin itu pada beberapa masa.
Ramalkan tinggi lilin itu selepas 45 minit.A burning candle gets shorter at the same rate. Table 1 shows the height of the candle at different times. Predict the height of the candle after 45 minutes.
| Masa (minit) / Time (minutes) | 0 | 10 | 20 | 30 |
|---|---|---|---|---|
| Tinggi lilin (cm) / Height of the candle (cm) | 12 | 10 | 8 | 6 |
Show answerHide answer
C
The candle gets 2 cm shorter every 10 minutes. From 30 minutes (6 cm) to 45 minutes is 15 minutes, which is 3 cm shorter. 6 − 3 = 3 cm.

Question 2
Antara yang berikut, amalan manakah dipadankan dengan betul dengan sistem badan yang dilindunginya?Which habit is matched correctly with the body system that it protects?
Show answerHide answer
A
Seat belts and helmets protect the skeletal system (textbook p. 40). Enough water helps the digestive system, avoiding cigarettes protects the respiratory system and calcium is for the bones.

Question 3
Rajah 1 menunjukkan siratan makanan di lantai hutan hujan. Anak panah bermaksud "dimakan oleh". Berapakah bilangan rantai makanan yang bermula dengan daun dan berakhir dengan helang?Diagram 1 shows a food web on a rainforest floor. The arrow means "is eaten by". How many food chains start with the leaves and end with the eagle?
Show answerHide answer
B
The chains are: leaves → grasshopper → frog → snake → eagle; leaves → grasshopper → lizard → snake → eagle; leaves → caterpillar → frog → snake → eagle. The lizard does not eat the caterpillar, so there are 3 chains.
4
Question 4
Tumbuhan manakah dipadankan dengan betul dengan ciri khas yang melindunginya daripada musuh?Which plant is matched correctly with the special characteristic that protects it from enemies?
Show answerHide answer
D
Bamboo has fine hairs that make the skin itchy. The durian has sharp thorns, the papaya tree produces latex and the allamanda is poisonous (textbook pp. 94–95).
5
Question 5
Rajah 2 menunjukkan satu litar bersiri dengan dua biji sel kering dan dua biji mentol yang sama, L dan M. Hamid menambah satu lagi mentol yang sama secara bersiri. Apakah yang berlaku kepada kecerahan mentol L dan M?Diagram 2 shows a series circuit with two dry cells and two identical bulbs, L and M. Hamid adds one more identical bulb in series. What happens to the brightness of bulbs L and M?
Show answerHide answer
C
In a series circuit there is only one path, so the electrical energy is shared by all the bulbs. More bulbs mean each bulb gets less, so all the bulbs become dimmer (textbook p. 125).
6
Question 6
Rajah 3 menunjukkan sebuah botol plastik dengan sebiji belon yang dipasang pada lehernya. Botol itu diletakkan di dalam mangkuk berisi air dan ketulan ais selama 10 minit. Apakah yang akan berlaku kepada belon itu?Diagram 3 shows a plastic bottle with a balloon fitted on its neck. The bottle is put in a bowl of water and ice cubes for 10 minutes. What will happen to the balloon?
Show answerHide answer
B
The air in the bottle loses heat to the ice, so it contracts and the balloon becomes smaller (textbook activity 3, p. 157). Gases expand when they gain heat and contract when they lose heat.
7
Question 7
Pagar besi sebuah sekolah dicat semula. Mengapakah mengecat pagar itu dapat mencegah pagar daripada berkarat?The iron fence of a school is painted again. Why does painting the fence prevent it from rusting?
Show answerHide answer
D
Iron rusts when it touches both water and air. A layer of paint keeps them away from the iron (textbook p. 170).
8
Question 8
Rajah 4 menunjukkan bacaan sebuah penimbang ketika sebuah bikar kosong ditimbang dan ketika bikar itu berisi minyak masak. Berapakah jisim minyak masak itu?Diagram 4 shows the reading on a balance when an empty beaker is weighed and when the beaker has cooking oil in it. What is the mass of the cooking oil?
Show answerHide answer
A
Mass of the oil = mass of the beaker with oil − mass of the empty beaker = 195 − 85 = 110 g (textbook p. 181).
9
Question 9
Empat pernyataan tentang Bulan diberikan di bawah.
W Bulan memancarkan cahayanya sendiri.
X Bulan mengambil masa yang sama untuk berputar sekali pada paksinya dan untuk mengelilingi Bumi sekali.
Y Fasa Bulan berlaku kerana kita melihat bahagian yang berbeza daripada separuh Bulan yang disinari Matahari.
Z Kita sentiasa melihat permukaan Bulan yang sama kerana Bulan tidak berputar.
Pernyataan manakah yang betul?Four statements about the Moon are given below.
W The Moon gives out its own light.
X The Moon takes the same time to rotate once on its axis as to revolve once around the Earth.
Y The phases of the Moon happen because we see different parts of the half of the Moon that is lit by the Sun.
Z We always see the same surface of the Moon because the Moon does not rotate.
Which statements are correct?

Z We always see the same surface of the Moon because the Moon does not rotate.
Which statements are correct?
Show answerHide answer
B
X and Y are correct (textbook pp. 201–204 and the Mind Reflection). W is wrong because the Moon only reflects the light of the Sun. Z is wrong because the Moon does rotate; the same surface faces the Earth because rotation and revolution take the same time, 27 days.
