The student starts the experiment by immersing a 0.5 N of slotted weight, Wo into a beaker of water as shown in Diagram 1.2. The reading of the compression balance, m is recorded. The student also calculate the value of Ww using Ww = mg.

The experiment is repeated with different weight of slotted weight, Wo = 1.0 N, 1.5 N, 2.0 N and 2.5 N. The corresponding readings for the compression balance are shown in Diagram 1.3, 1.4, 1.5 and 1.6 on pages 3 and 4.

Murid itu memulakan eksperimen dengan menenggelamkan pemberat berslot 0.5 N, Wo ke dalam bikar yang berisi air seperti ditunjukkan dalam Rajah 1.2. Bacaan neraca mampatan, m direkodkan. Murid itu menghitung nilai Ww menggunakan Ww = mg.

Eksperimen diulang dengan menggunakan pemberat berslot yang berbeza, Wo = 1.0 N, 1.5 N, 2.0 N dan 2.5 N. Bacaan yang sepadan untuk neraca mampatan ditunjukkan pada Rajah 1.3, 1.4, 1.5 dan 1.6 di halaman 3 dan 4.
