Sel kering membekalkan tenaga, mentol mengeluarkan cahaya, suis menyambungkan dan memutuskan litar, dan wayar menyambungkan komponen.
Langkah 1
Komponen mempunyai fungsi khusus
Sel kering membekalkan tenaga, mentol mengeluarkan cahaya, suis menyambungkan dan memutuskan litar, dan wayar menyambungkan komponen.
sel: tenaga | mentol: cahaya | suis: sambung / putus litar | wayar: sambung
fungsi komponen = 零件的功能 每个零件都有自己的工作:干电池供应能量,灯泡发光,开关控制电流的路,电线把零件连起来。 例子:在手电筒里,电池供电、按钮是开关、前面的小灯泡发光。 注意:灯泡和开关常被搞混:会亮的是灯泡,能按开按关的是开关。
fungsi komponen = functions of the parts Each part has its own job: the dry cell supplies energy, the bulb gives out light, the switch controls the path and the wires connect the parts. Example: In a torch, the batteries supply energy, the button is the switch and the small bulb at the front shines. Watch out: Pupils mix up the bulb and switch: the bulb shines, while the switch is the part you press on and off.
Langkah 2
Litar lengkap diperlukan
Mentol menyala apabila komponen baik disambungkan dalam laluan lengkap dan suis ditutup. Jurang atau kerosakan boleh menghentikan nyalaan.
litar lengkap diperlukan = a complete circuit is needed The bulb lights only when good parts are joined in a complete path and the switch is closed. A gap or a broken part stops the light. Example: One loose plug in a string of festive lights can make the whole string go dark. Watch out: All three conditions must hold together; two out of three still leaves the bulb dark.
Langkah 3
Bukti nyalaan mengelaskan bahan
Bahan yang membolehkan mentol menyala ialah konduktor. Bahan yang tidak membolehkan mentol menyala ialah penebat.
bukti nyalaan = evidence from the bulb A material that lets the bulb light is a conductor; one that keeps it dark is an insulator. The bulb's result is the evidence for classifying. Example: A brass key makes the bulb light, so it conducts; a strip of cloth keeps it dark, so it insulates. Watch out: State the evidence in your conclusion, for example: the bulb lit, therefore it is a conductor.

Komponen manakah menyambungkan dan memutuskan litar?
menyambung dan memutuskan litar = 接通和切断电路 题目问哪个零件能接通或切断电路。回想每个零件的工作:哪个会发光?哪个只是固定零件?哪个能让你决定电路通还是断? 例子:水龙头控制水流,转开水就流,转紧水就停。 注意:mengawal 是“控制”,要找能改变电路状态的零件。
menyambung dan memutuskan litar = connecting and breaking the circuit The question asks which part can join or break the path of current. Recall each part's job: which one shines, which one only holds another part, and which one lets you decide on or off? Example: A water tap controls the flow: turn it open and water runs, turn it shut and it stops. Watch out: Mengawal means control, so look for the part that changes the state of the circuit.

bilakah mentol menyala = when the bulb lights The question asks in which situation the bulb lights. Use the conditions from step 2: is there an energy source, is the path unbroken, and what state is the switch in? Every condition must be met. Example: A doorbell rings only when it has a battery, its wires are joined and its button is pressed. Watch out: Check every condition in a choice; reading only the first half can lead you astray.
