Aina menyiasat sama ada tempoh cahaya matahari yang diterima mempengaruhi ketinggian anak benih kacang. Jadual 1 menunjukkan keputusannya selepas 10 hari.

Tempoh cahaya matahari sehari (jam) / Hours of sunlight per day	Ketinggian anak benih (cm) / Height of seedling (cm)
2	3
4	6
6	9

Jadual 1
Apakah kesimpulan yang betul?Aina investigates whether the time a bean seedling spends in the sunlight affects its height. Table 1 shows the results after 10 days. What is the correct conclusion?

Semakin lama anak benih berada di bawah cahaya matahari, semakin tinggi anak benih itu.The longer the seedling is in the sunlight, the taller it grows.
Semakin lama anak benih berada di bawah cahaya matahari, semakin rendah anak benih itu.The longer the seedling is in the sunlight, the shorter it is.
Semua anak benih mempunyai ketinggian yang sama.All the seedlings have the same height.
Anak benih itu bertambah tinggi kerana disiram dengan lebih banyak air.The seedling grows taller because it is given more water.

Show answerHide answer

The height goes up from 3 cm to 6 cm to 9 cm as the hours of sunlight go from 2 to 4 to 6. So the longer the seedling is in the sunlight, the taller it grows. The table says nothing about the amount of water (textbook p. 8).

A heart. Vessel P leaves the heart towards the lungs and vessel Q leaves it towards the whole body. — Rajah 1Diagram 1

P membawa darah yang kaya dengan oksigen dan Q membawa darah yang kaya dengan karbon dioksida.P carries blood rich in oxygen and Q carries blood rich in carbon dioxide.
P membawa darah yang kaya dengan karbon dioksida ke peparu dan Q membawa darah yang kaya dengan oksigen ke seluruh badan.P carries blood rich in carbon dioxide to the lungs and Q carries blood rich in oxygen to the whole body.
P dan Q kedua-duanya membawa darah yang kaya dengan oksigen.Both P and Q carry blood rich in oxygen.
P dan Q kedua-duanya membawa darah yang kaya dengan karbon dioksida.Both P and Q carry blood rich in carbon dioxide.

Show answerHide answer

The right side of the heart pumps blood rich in carbon dioxide to the lungs (P). The left side pumps blood rich in oxygen to the whole body (Q) (textbook p. 30).

Rajah 3 menunjukkan tiga litar bersiri, X, Y dan Z. Semua mentol adalah serupa dan semua suis ditutup. Di dalam litar manakah mentol paling terang?Diagram 3 shows three series circuits, X, Y and Z. All the bulbs are identical and all the switches are closed. In which circuit are the bulbs the brightest?

Circuit X: one dry cell and two bulbs in series — Rajah 3: litar XDiagram 3: circuit X

Circuit Y: two dry cells and two bulbs in series — Rajah 3: litar XDiagram 3: circuit X

Litar XCircuit X
Litar ZCircuit Z
Litar Y dan litar Z, kerana kedua-duanya mempunyai dua sel keringCircuits Y and Z, because both have two dry cells
Litar YCircuit Y

Show answerHide answer

More dry cells make the bulbs brighter and more bulbs in a series circuit make each bulb dimmer. Y has the most dry cells for its two bulbs (2 cells for 2 bulbs). Z has the same 2 cells shared by 3 bulbs, so its bulbs are dimmer. X has only 1 cell for 2 bulbs (textbook pp. 123–127).

For the teacher: Analysing, medium difficulty, Unit 5, standard 5.2.3

Textbook p. 124

Sebuah jambatan mempunyai jurang di antara dua bahagian logamnya. Seorang jurutera mengukur jurang itu pada tiga masa. Jadual 3 menunjukkan keputusannya.

Masa / Time	Suhu udara (°C) / Air temperature (°C)	Jurang (cm) / Gap (cm)
7 a.m.	24	5
1 p.m.	38	2
8 p.m.	27	4

Jadual 3
Apakah yang boleh disimpulkan daripada Jadual 3?A bridge has a gap between two of its metal sections. An engineer measures the gap at three times of the day. Table 3 shows the results. What can be concluded from Table 3?

Logam mengecut apabila suhu meningkat, jadi jurang menjadi lebih kecil.The metal contracts when the temperature rises, so the gap becomes smaller.
Logam mengembang apabila suhu meningkat, jadi jurang menjadi lebih kecil.The metal expands when the temperature rises, so the gap becomes smaller.
Logam mengembang apabila suhu menurun, jadi jurang menjadi lebih besar.The metal expands when the temperature falls, so the gap becomes bigger.
Jurang tidak berubah kerana logam tidak menerima haba.The gap does not change because the metal does not gain heat.

Show answerHide answer

The hotter it is, the smaller the gap: 24 °C gives 5 cm, 27 °C gives 4 cm and 38 °C gives 2 cm. The metal sections expand when they gain heat and take up the space of the gap (textbook p. 158).

(i) Nail 1 is wrapped in a wet cloth and left in an open dish.
(ii) Nail 2 is placed in a closed box with anhydrous calcium chloride, which absorbs moisture.

Show answerHide answer

(i) Rusts (it has water and air)1
(ii) Does not rust (there is no water)1

Iron rusts only when water and air are both present. Anhydrous calcium chloride keeps the box dry (textbook p. 169).

Tick each point you got.

[2 marks] (b)Tulis huruf bagi dua cara yang betul untuk mencegah objek besi daripada berkarat.
A Membiarkan objek itu di dalam hujan
B Menyapu minyak atau gris pada objek itu
C Mengecat objek itu
D Merendam objek itu di dalam airWrite the letters of two correct ways to prevent iron objects from rusting.
A Leave the object in the rain
B Apply oil or grease on the object
C Paint the object
D Put the object in water

Show answerHide answer

B (oil or grease keeps water and air away)1
C (paint covers the surface so water and air cannot touch the iron)1

Both correct ways make a cover over the iron so that water and air cannot reach it (textbook p. 170). A and D give the iron more water.
