Form 4
1. Experiment on physic's law..e.g gases law, etc
2. Experiment on physics' formula..e.g P=hpg , 1/f =1/u+1/v (light)

Form 5
1. Experiment of Interference of wave (water or sound or light wave)
2. Experiment of Electricity (Length of wire affect resistance or Thickness of wire affect resistance or temperature affect resistance)

PAPER 2 TIPS

In essay question paper 2 section B and C, the question will provide you with a table of comparison. For example, if the will question ask you to choose a material from a table to build an electric kettle….then you are asked to choose the most suitable material.


Example:


Kettle

The characteristics of the materials are used in the heating element in the kettle

Boiling point / 0C

Resistivity / 10-8 Wm

W

3501

13.5

X

1085

5.2


To score this section it’s easier if you to answer it by making a table of comparison like this:


Suitable Characteristic

Reason

High Boiling Point (1 mark)

Not easily melt (1 mark)

High Resistivity (1 mark)

It can produce more heat ( 1 mark)


Then you’ll choose which one is the most suitable and repeat its suitable characteristic.

Example:
Kettle W is most suitable coz it has high boiling point & high resistivity. [2 marks]

If you answer in table form, you are more focused and will go straight to the point.

Otherwise if you choose to write like typical english essay... there's a tendency for you to repeat the points.
