Gunakan kotak terpakai, sel kering, mentol, suis dan wayar bersalut yang disediakan guru. Minta bantuan orang dewasa apabila wayar perlu dibentuk atau dipotong.
Langkah 1
Sediakan bahan dengan pengawasan
Gunakan kotak terpakai, sel kering, mentol, suis dan wayar bersalut yang disediakan guru. Minta bantuan orang dewasa apabila wayar perlu dibentuk atau dipotong.
bahan selamat + pengawasan
bahan dengan pengawasan = 在大人看管下准备材料 用老师准备的干电池、有外皮的电线和轻的材料。要弯电线或剪电线时,请大人帮忙。 例子:做“我的英雄”纸盒人时,老师先帮忙把电线剪好、剥好两端,再把灯泡装在英雄的胸口。 注意:只用干电池做实验,绝对不能把电线插进家里的插座。
bahan dengan pengawasan = materials under supervision Use the dry cells, coated wires and light materials your teacher provides. Ask an adult for help when a wire must be bent or cut. Example: For a cardboard hero model, the teacher cuts the wire and strips both ends first. Watch out: Use only dry cells; never push wires into a wall socket at home.
Langkah 2
Bentuk sambungan yang kemas
Ikut lakaran asal sendiri dan pastikan setiap hujung wayar menyentuh terminal yang betul. Elakkan wayar bersilang secara longgar.
sambungan yang kemas = tidy connections Follow your own sketch and make sure each wire end touches the correct terminal. Avoid wires crossing loosely over each other. Example: If your sketch shows a wire from the + terminal to the bulb, start the real wire at the + terminal too. Watch out: The plastic coating does not conduct, so the bare metal end must be what touches the terminal.
Langkah 3
Uji dan terangkan hasil
Tekan suis dan perhatikan mentol di dada wira menyala, kemudian kaitkan hasil dengan litar lengkap. Putuskan sambungan selepas aktiviti.
uji → perhati → terangkan → putus sambungan
uji dan terangkan hasil = 测试并说明结果 按下开关,看英雄胸口的灯泡亮不亮,然后用“电路完整”来解释结果。活动结束后,要把电线拆开。 例子:英雄胸口的灯泡亮了,因为电从电池出发,经过灯泡又回到电池。 注意:做完不拆线,电池会一直耗电,很快没电,还可能发热。
uji dan terangkan hasil = test and explain the result Watch whether your model moves or works, then explain the result using the idea of a complete circuit. Disconnect the wires after the activity. Example: The bulb on the hero's chest lights up because electricity leaves the cell, passes through the bulb and returns to the cell. Watch out: If you leave it connected, the cell keeps draining, goes flat quickly and may get warm.

Siapakah patut membantu jika wayar perlu dipotong?
memotong wayar = cutting wire The question asks who should help when a wire must be cut. Scissors and wire ends are sharp, so think about who has the experience to use tools safely and look after you. Example: When fruit needs cutting in the kitchen, someone skilled with knives should watch over you too. Watch out: Patut means should, so pick the safest choice, not the most convenient one.

hujung wayar = wire ends The question asks what to check at the end of a wire. Recall step 2: for electricity to flow into the cell, what must happen between the wire end and the cell? Also ask which choices have nothing to do with current. Example: Earphones stay silent if the plug is not pushed all the way in. Watch out: The question asks only about the ends, not the whole wire, so focus on that spot.
