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
Rajah 1 menunjukkan satu corak bentuk. Ramalkan bentuk yang seterusnya di tempat bertanda ?.Diagram 1 shows a pattern of shapes. Predict the next shape at the place marked ?.
Show answerHide answer
A
The pattern repeats: triangle, circle, circle. The row ends with a triangle and one circle, so the next shape is another circle. A prediction uses the pattern as a clue (textbook p. 11).
2
Question 2
Mengapakah kita perlu membuka semua pintu dan tingkap sebelum memulakan aktiviti di dalam bilik sains?Why must we open all the doors and windows before an activity in the Science Room?
Show answerHide answer
B
We open the doors and windows to let in light and fresh air. A closed room becomes hot, dark and stuffy (textbook p. 24).

Question 3
Bahagian gigi manakah ialah lapisan luar yang keras dan putih serta melindungi gigi?Which part of a tooth is the hard, white outside layer that protects the tooth?
Show answerHide answer
D
Enamel is the hard, white outside layer of a tooth and it protects the tooth. Dentine is the layer under the enamel.
4
Question 4
Bayangkan seekor kambing yang mempunyai gigi taring yang panjang dan tajam seperti singa, bukan gigi kacip dan geraham. Mengapakah kambing itu sukar untuk makan rumput?Imagine a goat that has long, sharp canines like a lion, instead of incisors and molars. Why would the goat find it hard to eat grass?
Show answerHide answer
C
A herbivore needs incisors to cut plants and molars to grind them. Sharp canines tear meat, so they cannot cut or grind grass well. The teeth must suit the food (textbook pp. 65-66).
5
Question 5
Pasangan tumbuhan manakah yang membiak melalui biji benih?Which pair of plants reproduces through seeds?
Show answerHide answer
A
Plants that make fruits reproduce through seeds. Chilli and durian have seeds inside their fruits. Fern and mushroom use spores, ginger and potato are underground stems, and banana and yam grow suckers (textbook p. 72).
6
Question 6
Rajah 4 menunjukkan kubus kecil yang disusun untuk memenuhi sebuah kotak dengan tepat. Isi padu setiap kubus ialah 1 cm³. Berapakah isi padu kotak itu?Diagram 4 shows small cubes packed to fill a box exactly. The volume of each cube is 1 cm³. What is the volume of the box?
Show answerHide answer
C
The block is 4 cubes long, 2 cubes high and 2 cubes deep. Each layer has 4 × 2 = 8 cubes and there are 2 layers, so 8 × 2 = 16 cubes = 16 cm³. 13 cm³ is wrong because it counts only the cubes we can see; 3 cubes are hidden at the back and bottom.
7
Question 7
Sebatang kayu balak yang besar dan berat terapung di atas air, tetapi sehelai getah gelang yang kecil dan ringan tenggelam. Pernyataan manakah yang menerangkan perkara ini?A big, heavy log floats on water, but a small, light rubber band sinks. Which statement explains this?
Show answerHide answer
B
Floating and sinking depend on density, not on size or weight. The log is heavy but less dense than water, so it floats. The rubber band is light but more dense than water, so it sinks (textbook p. 99).
8
Question 8
Seekor lebah menyengat Ahmad. Sengatan lebah bersifat berasid. Bahan manakah yang sesuai disapu pada sengatan itu sebagai pertolongan cemas?A bee stings Ahmad. A bee sting is acidic. Which substance is suitable to put on the sting as first aid?
Show answerHide answer
D
An acid and an alkali cancel each other out. Sodium bicarbonate is alkaline, so it cancels the acidic bee sting. Vinegar, lime juice and tamarind juice are acidic (textbook p. 111).
9
Question 9
Planet manakah yang paling jauh dari Matahari dan paling sejuk?Which planet is the farthest from the Sun and the coldest?
Show answerHide answer
D
Neptune is the eighth planet, so it is the farthest from the Sun. The farther a planet is from the Sun, the colder it is, so Neptune is the coldest (textbook p. 121).
10
Question 10
Rajah 7 menunjukkan nelayan menarik pukat dengan bantuan takal. Apakah beban yang dinaikkan oleh takal itu?Diagram 7 shows fishermen pulling up a net with the help of a pulley. What is the load that the pulley lifts?
Show answerHide answer
B
A load is the heavy thing we want to lift. The pulley helps the fishermen lift the heavy net full of fish (textbook p. 131).
