Pokok jagung membesar mengikut peringkat: biji benih → anak benih bercambah → anak pokok → pokok dewasa. Rekod tarikh atau hari supaya pemerhatian boleh dibandingkan dengan adil.
Langkah 1
Perhati pada selang masa
Pokok jagung membesar mengikut peringkat: biji benih → anak benih bercambah → anak pokok → pokok dewasa. Rekod tarikh atau hari supaya pemerhatian boleh dibandingkan dengan adil.
biji benih → anak benih bercambah → anak pokok → pokok dewasa
Perhati pada selang masa = observe at time intervals We see a plant's growth only when we observe the same plant several times. Write down the date or day number each time so the comparison is fair and clear. Example: A bean seedling is 2 cm on day 1, 5 cm on day 4 and 9 cm on day 7. Watch out: Always observe the same plant; switching to a different plant spoils the comparison.
Langkah 2
Daun berubah
Semasa tumbuhan membesar, bilangan daun biasanya bertambah dan saiz daun menjadi lebih besar. Kira daun dan ukur daun menggunakan unit yang sama.
bilangan daun ↑ + saiz daun ↑
Daun berubah = 叶子会变化 植物长大时,叶子通常会变多,也会变大。可以数叶子的数量,也可以用同一种单位量叶子的长度。 例子:辣椒苗第一周有 2 片叶子,第三周有 6 片,最大的叶子从 2 cm 长到 4 cm。 注意:数叶子时每片只算一次,不要重复数。
Daun berubah = leaves change As a plant grows, it usually gets more leaves and bigger leaves. Count the leaves, and measure leaf length using the same unit each time. Example: A chilli seedling has 2 leaves in week 1 and 6 in week 3, and its largest leaf grows from 2 cm to 4 cm. Watch out: Count each leaf only once so the number is not doubled.
Langkah 3
Pokok dan batang membesar
Ketinggian pokok dan lilitan batang boleh bertambah semasa tumbesaran. Gunakan pembaris atau pita ukur dengan cara yang sama setiap kali merekod.
tinggi pokok ↑ + lilitan batang ↑
Pokok dan batang membesar = 植物和茎会长大 植物长大时,株高会增加,茎的粗细(一圈的长度)也会增加。每次都用同一把尺或卷尺、同一种方法量。 例子:用卷尺绕木瓜树干一圈,三月量到 20 cm,六月量到 24 cm。 注意:量株高要从泥土表面量起,不是从花盆底量起。
Pokok dan batang membesar = plant and stem grow As a plant grows, its height and the distance around its stem both increase. Use the same ruler or measuring tape in the same way each time. Example: Wrap a tape around a papaya trunk: 20 cm in March and 24 cm in June. Watch out: Measure height from the soil surface, not from the bottom of the pot.

Mengapakah tumbuhan diperhatikan pada beberapa hari berbeza?
Perhati pada hari berbeza = 在不同日子观察 这题问为什么要在好几天观察同一棵植物。想一想:只看一天,能不能知道它有没有长高?检查每个选项,是不是在讲观察的目的,而不是在改变植物。 例子:每个月替妹妹量一次身高,是为了知道她长高了多少。 注意:观察只是看和记录,不会把植物变成别的东西。
Perhati pada hari berbeza = observe on different days This question asks why we observe one plant on several different days. Think: can a single day show whether it grew taller? Check whether each choice explains the purpose of observing, rather than changing the plant. Example: Measuring a little sister's height once a month shows how much she has grown. Watch out: Observing means looking and recording; it never turns a plant into something else.

Perubahan manakah biasa berlaku pada bilangan daun?
Perubahan bilangan daun = 叶子数量的变化 这题问植物长大时,叶子数量通常有什么变化。回想观察记录:第一周和第三周的叶子数一样吗?检查每个选项合不合真实植物的样子。 例子:家里的九层塔,买回来时 5 片叶子,两周后数到 12 片。 注意:要用观察到的证据来判断,不要选不可能在现实发生的事。
Perubahan bilangan daun = change in leaf number This question asks how the number of leaves usually changes as a plant grows. Recall the observation records: did week 1 and week 3 have the same count? Check each choice against what real plants do. Example: A basil plant bought with 5 leaves had 12 leaves two weeks later. Watch out: Judge using observed evidence and reject anything that could never happen in real life.
