Bekas penyukat perlu tegak dan stabil supaya bacaan tidak berubah.
Langkah 1
Letak bekas pada permukaan rata
Bekas penyukat perlu tegak dan stabil supaya bacaan tidak berubah.
bekas tegak + meja rata
permukaan rata = 平的桌面 量杯要放在平平的桌面上,并且站直。量杯歪了,水面也会斜,读出来的数就不准。 例子:量杯放在平桌上读到 300 mℓ,拿在手里晃着读成 350 mℓ,多读了 350 - 300 = 50 mℓ。 注意:不要一手拿量杯一手倒水,量杯容易歪。
permukaan rata = flat surface Stand the measuring container upright on a flat table. If the container leans, the surface of the liquid tilts too, and the reading becomes wrong. Example: on a flat table the jug reads 300 mℓ, but held in a shaky hand it seems like 350 mℓ, an error of 350 - 300 = 50 mℓ. Watch out: do not hold the jug in one hand while pouring with the other, because it will tip.
Langkah 2
Baca pada aras mata
Rendahkan mata hingga sama aras dengan permukaan cecair sebelum membaca senggatan.
mata ↔ aras cecair
aras mata = 眼睛的高度 读刻度时,蹲下来让眼睛和水面一样高。从上往下看会读得太多,从下往上看会读得太少。 例子:平视读到 200 mℓ,从上方斜看好像 220 mℓ,差了 220 - 200 = 20 mℓ。 注意:水面边缘会微微弯起来,要看中间平的那条线。
aras mata = eye level When reading the marks, bend down until your eyes are level with the top of the liquid. Looking from above makes the reading too high, and looking from below makes it too low. Example: at eye level the reading is 200 mℓ, but from above it looks like 220 mℓ, off by 220 - 200 = 20 mℓ. Watch out: the liquid curves up a little at the sides, so read the flat middle line.
Langkah 3
Rekod dengan unit
Tulis bacaan bersama simbol mℓ atau ℓ yang ditunjukkan pada bekas.
rekod dengan unit = record with the unit After reading, write the number with the unit printed on the container, such as 250 mℓ or 2 ℓ. Without the unit nobody can tell if it is a little or a lot. Example: measure 250 mℓ, then add another 250 mℓ, giving 250 + 250 = 500 mℓ. Watch out: 2 ℓ and 2 mℓ are very different; a big jug of water is never just 2 mℓ.

bekas penyukat = measuring container The question asks where the measuring container should be placed while measuring. Think about where the liquid stays level and the container will not fall over. Look back at the picture in Langkah 1 to check. Example: a jug holds 400 mℓ of water, 150 mℓ is poured out, and 400 - 150 = 250 mℓ is left. Watch out: when the container wobbles the liquid moves, so the reading cannot be trusted.

Mata perlu berada…
kedudukan mata = 眼睛的位置 题目问:读量杯刻度时,眼睛要放在哪个位置。回想 Langkah 2,想一想从不同高度看水面,读到的数会不会变。 例子:量杯里有 300 mℓ 果汁,喝了 100 mℓ,剩 300 - 100 = 200 mℓ。 注意:站着低头看量杯,是常见的读错原因。
kedudukan mata = position of the eyes This question asks where your eyes should be when reading the marks on a measuring jug. Recall Langkah 2 and think about whether the reading changes when you look from different heights. Example: a jug has 300 mℓ of juice, 100 mℓ is drunk, and 300 - 100 = 200 mℓ remains. Watch out: standing up and looking down at the jug is a very common cause of misreading.
