PART B Paper 3 Planning Experiment
1. Identify the MV and RV from the diagram and questions. CIRCLE IT UP
2. Identify the apparatus given to link to the PHYSICS CONCEPT of experiment.
3. Relate the experiment which you had done before in school and identity the relationship
between the variables.
4.
Identity the variable from the text and diagram.
(a) Manipulated variable
(b) Responding variable
(c) Fixed variable (can be measured)
---NOT TYPE OF SUBSTANCE
Underline the variables of MV and RV from the diagram. Use the variables to substitute
the format of Planning Experiment.
1. Procedure
1. State the initial measurement of MV.
2. State the ways of measurement of RV with apparatus and follow with formula (if
necessary)
3. Repeat the experiment with 4 different MV values. a1,a2,a3 and a4.
2.
Diagram 3.1 shows two toy trains which have same pulling force at the starting line. Diagram
3.2 shows the positions of toy trains after they are switched on.
With the use of apparatus such as trolleys, ticker timer and other apparatus,
describe an experiment framework to investigate the hypothesis stated in 3 (b).
3. A man who is fishing, pulled out a fish out of the water as shown in Diagram 3.1. It
becomes more difficult to pull out the fish out of the water and the rod is getting bender
in Diagram 3.2.
With the use of apparatus such as measuring cylinder, spring balance, metal rod and
other apparatus, describe an experiment framework to investigate the hypothesis stated
in3(b)
4. Diagram 3.1 shows a diver is diving into the sea. Diagram 3.2 shows a diver is diving into the
swimming pool. They are at the same depth but the diver in Diagram 3.1 feel that his ear
was sick.
5. Diagram 3 shows a dented ping pong ball then put in a basin that consist cold water
(Diagram 3 (a)), warm water (Diagram 3 (b)), and hot water (Diagram 3 (c)). Observe
the shape of ping pong ball and their surroundings.
With the use of apparatus such as a thermometer, capillary tube, bunsen burner and other
apparatus, describe an experiment framework to investigate the hypothesis stated in 3 (b).

6. Diagram 3.1 shows a worker pushing down on piston of a clogged bicycle pump. Diagram
3.2 shows the same worker finding it harder to push the piston further down.
With the use of apparatus such as a Bourdon gauge and other apparatus, describe an
experiment to investigate the hypothesis stated in 3 (b).
3(a)
Temperature influence the size of pingpong ball.
3(b)
When the temperature increases, the height of air trapped also
increases.
3(c)(i)
To study the relationship between temperature and volume/height
3(c)(ii)
MV – temperature
RV – Height of air traped/volume
FV – pressure
3(c)(iii)
Capillary tube, thermometer, beaker, ruler, stirrer, tripod stand,
bunsen burner, rubber bands and retort stand with clamp.
3(c)(iv)
Charles’ Law experiment.
3(c)(v)
The experiment is set up as shown.

When the thermometer is θ = 30 C, the height of the air column, h is
read on the ruler scale and record.
