Constant / Control / Fixed variable =what is kept the sameKey word – same / equivalent

Manipulated variable = what is changedKey word – different

Responding variable = what is observedResult / outcome / what is tested /what to record / what to note down

a) Based on the results, write one statement relating thetwo variables.Answer 1: The higher the temperature the faster the

sugar melts.Correct Answer: The higher the water temperature, the

faster the time taken for the sugar todissolve.

The quantity of sugar dissolved in water depends on thevolume of water used.

b) Write one hypothesis based on the statement above.Answer 1: The more the quantity of sugar dissolved in the

water, the more the volume of water used.Correct Answer: The more the volume of water used, the

more the quantity of sugar dissolved inthe water.

4. Figure below shows three electriccircuits, R, S and T. The

brightness of the bulbs arerecorded.



03/06/09 HENRY HCH

a) What is the purpose (aim) of this investigation?Answer 1: The effect of number of bulbs on the

brightness of bulbs.

Answer 2: To investigate whether the number of bulbscan affect the brightness of bulbs.Answer 3: To investigate the number of bulbs and the

brightness of bulbs.Answer 4: To investigate the effect of brightness of

bulbs on the number of bulbs.

Correct Answer 1: To investigate the relationship betweenthe number of bulbs used and thebrightness of the bulbs.

Correct Answer 2: To study the effect of number of

bulbs used on the brightness of thebulbs.

D. OBSERVATIONS &

INFERENCESObservationOver all what can we see from the question (diagram /table / graph)If the question has more than one figure, we have tostate the comparison.

Inference = ReasonTo explain the cause and the effect of an observation

Must be logical and involve Science fact / conceptAnswer base on your observation, if observation iscomparative, inference must be comparative as well.

5. Amin carried out an investigation. He prepared thefollowing circuit. An eraser and a thumbtack is connectedto the circuit.

a) State two observations in the investigation.Answer 1: (i) The bulb will light up when thumbtack isconnected to the circuit.

(ii) The bulb will not light up when eraser isconnected to the circuit.

Correct Answer:

(i) The bulb will light up when thumbtack is connected tothe circuit but not the eraser.(ii) The thumbtack will become hot when it is connected

to the circuit but not the eraser.
