1. A group of students carried out an experiment to investigate the growth rate of seedlingin different types of soil.

Sekumpulan pelajar menjalankan eksperimen untuk mengkaji kadar pertumbuhan

sejenis biji benih dalam tanah yang berlainan jenis.

The following steps were carried out:

Langkah-langkah yang dijalankan adalah seperti berikut:

Step 1 : Two seedling trays are filled with 300g of sandy soil and loamy soil

respectively.

Langkah 1 : Dua buah bekas semaian masing-masing diisi dengan 300g tanah

berpasir dan tanah gembur.

Step 2 : Three red bean seeds are planted at 5 cm interval in each seedling tray.Langkah 2 : Tiga biji kacang merah ditanam dengan jarak 5 cm antara satu sama

lain ke dalam setiap bekas semaian.

Step 3 : Each tray is watered with 30ml of water daily.

Langkah 3 : Setiap bekas semaian disiram dengan 30ml air setiap hari.

Step 4 : After 3 days, the length of the seedling roots are measured by using a

thread as shown in Diagram 1.

Langkah 4 : Selepas 3 hari, panjang akar biji benih diukur menggunakan benang

seperti yang ditunjukkan pada Rajah 1.
