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.
