1
Question 1
Lina ingin mengetahui sama ada saiz balang kaca mempengaruhi masa lilin menyala. Dia meletakkan lilin yang sama di bawah balang yang berlainan saiz dan mencatat masa lilin padam.
Apakah pemboleh ubah dimanipulasikan dalam penyiasatan ini?Lina wants to find out whether the size of a glass jar affects how long a candle burns. She puts the same candle under jars of different sizes and records the time until the flame goes out. What is the manipulated variable in this investigation?
| Saiz balang / Size of jar | Kecil / Small | Sederhana / Medium | Besar / Large |
|---|---|---|---|
| Masa lilin menyala / Time the candle burns | 6 s | 11 s | 17 s |
Show answerHide answer
B
The manipulated variable is the one the investigator changes on purpose: the size of the jar. The time the candle burns is measured, so it is the responding variable. The candle is the same each time, so it is a constant variable.

Question 2
Seorang murid menyentuh cerek yang panas dan serta-merta menarik tangannya sebelum dia sempat berfikir. Apakah yang berlaku?A pupil touches a hot kettle and pulls her hand away at once, before she has time to think. What happens?
Show answerHide answer
D
This is a reflex action: it is fast and happens without thinking. It is controlled by the spinal cord, so the message does not have to reach the brain first. The heart does not carry messages, and the nervous system is always involved.

Question 3
Seekor ketam pertapa membawa anemon laut di atas cangkerangnya. Anemon laut melindungi ketam daripada musuh. Ketam membawa anemon laut ke tempat yang lebih banyak makanan. Apakah jenis interaksi ini?A hermit crab carries a sea anemone on its shell. The sea anemone protects the crab from enemies. The crab carries the sea anemone to places with more food. What type of interaction is this?
Show answerHide answer
A
Both animals gain, so this is mutualism. In parasitism one living thing is harmed, in commensalism one gains and the other is not affected, and in prey-predator one animal eats the other.
4
Question 4
Sebuah hutan dibersihkan untuk ladang kelapa sawit. Bilangan orang utan di hutan itu semakin berkurang. Apakah sebab utama bilangan orang utan berkurang?A forest is cleared for an oil palm plantation. The number of orangutans in the forest keeps falling. What is the main reason?
Show answerHide answer
C
Destruction of habitat is a human activity that threatens animals. When the forest is cleared, the orangutans lose their home and their food, so their numbers fall.

Question 5
Jadual menunjukkan jarak yang dilalui oleh sebuah kereta mainan pada empat permukaan yang berlainan. Kereta mainan itu dilepaskan dari bahagian atas landasan yang sama.
Permukaan manakah yang mempunyai daya geseran paling besar?The table shows the distance travelled by a toy car on four different surfaces. The toy car is released from the top of the same ramp. Which surface has the largest frictional force?
| Permukaan / Surface | P | Q | R | S |
|---|---|---|---|---|
| Jarak / Distance (cm) | 120 | 45 | 80 | 150 |
Show answerHide answer
B
The larger the frictional force, the sooner the toy car stops and the shorter the distance it travels. Q has the shortest distance, 45 cm, so Q has the largest friction. S, at 150 cm, is the smoothest.
6
Question 6
Sisa makanan manakah yang paling sesuai dijadikan kompos?Which waste is the most suitable to be made into compost?
Show answerHide answer
C
Compost is made from biodegradable waste, which microorganisms can decompose. Vegetable peels and fruit leftovers are biodegradable. Plastic, aluminium and glass are non-biodegradable.

Question 7
Rajah 1 menunjukkan Bulan berada di antara Matahari dan Bumi. Titik X di Bumi berada di dalam penumbra bayang-bayang Bulan. Apakah yang dilihat oleh pemerhati di X?Diagram 1 shows the Moon between the Sun and Earth. Point X on Earth is inside the penumbra of the Moon's shadow. What does an observer at X see?
Show answerHide answer
A
The Moon is between the Sun and Earth, so this is an eclipse of the Sun. In the penumbra only part of the sunlight is blocked, so X sees a partial eclipse. A total eclipse is seen only inside the umbra. An eclipse of the Moon needs Earth to be in the middle.

Question 8
Antara berikut, yang manakah menunjukkan urutan yang betul dari yang terkecil kepada yang terbesar?Which shows the correct order from the smallest to the largest?
Show answerHide answer
D
Earth is a planet in the Solar System. The Solar System is a small part of the Milky Way galaxy, and there are billions of galaxies in the universe.

Question 9
Raju membuat tiga rasuk daripada kad manila yang sama saiz. Dia meletakkan setiap rasuk di antara dua meja dan menambah buku sehingga rasuk itu bengkok.
Apakah kesimpulan yang betul daripada penyiasatan ini?Raju makes three beams from manila card of the same size. He puts each beam between two desks and adds books until the beam bends. What is the correct conclusion from this investigation?
| Rasuk / Beam | Bentuk / Shape | Bilangan buku / Number of books |
|---|---|---|
| X | Kad rata / Flat card | 2 |
| Y | Kad dilipat seperti huruf V / Card folded into a V | 5 |
| Z | Kad digulung menjadi silinder / Card rolled into a cylinder | 8 |
Show answerHide answer
C
Only the shape changes (the card, its size and the desk gap are the same), and the cylinder holds the most books, 8. So shape affects strength and the cylinder is strongest. The material is the same in all three beams, and height and stability are not tested.
