1. The population distribution of an organism is influenced by the changes in the
biotic and abiotic factors. A group of students carried out an investigation to study
how biotic factor such as food availability affects the population of garden snail in
different school area using the method of capture, mark, release and recapture
technique .
Penyebaran populasi organisma dipengaruhi oleh perubahan faktor-faktor biotik dan abiotik.
Sekumpulan pelajar telah menjalankan kajian mengkaji kesan faktor biotik seperti bekalan makanan
ke atas populasi siput babi dalam dua kawasan sekolah yang berbeza dengan menggunakan kaedah
tangkap, tanda, lepas dan tangkap semula .
These were the steps that has been carried out.
Berikut adalah antara langkah-langkah yang telah dijalankan .
Step 1 : An area of study with 2500m2 in the school field and school garden are
selected.
Satu kawasan kajian seluas 2500m2 di kawasan padang dan kebun sekolah dikenalpasti.
Step 2: Garden snails are captured randomly from each site and the number of garden
snails captured is recorded.
Sejumlah siput babi telah ditangkap secara rawak dari kedua-dua kawasan
dan dicatatkan bilangannya.
Step 3 : Garden snails that have been captured are marked with a small dot of Indian
ink on their shell and released into the same location where they were found.
Siput babi yang telah ditangkap, ditanda sedikit dengan dakwat India di atas cengkerangnya
dan kemudiannya dilepaskan semula ke dalam habitat asal.
Step 4 : After 4 days, a second captured is made at random from the same study area.
Selepas 4 hari, tangkapan kedua dibuat secara rawak dari kawasan kajian yang sama .
Step 5 : The total number of garden snails and the number of marked garden snails are
recorded.
Jumlah bilangan siput babi dan bilangan siput babi yang bertanda dalam tangkapan kedua
direkodkan.
Step 6 : The population size of garden snails at school field and school garden are
estimated.
Saiz populasi siput babi di kawasan padang dan kebun sekolah dianggarkan.

2. Siti washed the windows and floor of her house every morning. However, she
observed that in the afternoon, the windows and floor are always covered with a layer
of dust particles. Her house is located nearby an industrial factory which is 0.6 km
away from her house. Thick dark smoke is always being emitted from the factory
chimney. There is no complaint from her friend house which is located 5 km away
from Siti house.
Described how a group of students can plan a simple experiment to estimate the level
of air pollution in that area.
The planning of the investigation should cover the following aspects:

mendapati tingkap dan lantai rumahnya sentiasa diliputi dengan lapisan habuk. Rumah Siti
terletak berdekatan dengan satu kawasan kilang perindustrian yang terletak lebih kurang 0.6
km dari rumahnya. Asap tebal yang gelap sentiasa dikeluarkan dari cerobong asap kilang
perindustrian tersebut. Tiada sebarang rungutan kedengaran dari rakannya yang rumahnya
terletak 5 km dari rumah Siti.
Terangkan bagaimana sekumpulan pelajar boleh merancang satu eksperimen yang ringkas
untuk menganggar tahap pencemaran udara bagi kawasan tersebut.
Perancangan eksperimen harus mempunyai aspek-aspek:
 Problem statement
Pernyataan masalah
 Statement of hypothesis
Hipotesis
 Variables
Pembolehubah
 List of apparatus and materials
Senarai radas dan bahan
 Experimental procedure
