Section C : ExperimentingSTEPS1. From the statement given, underline the words showing the manipulated and

responding variable2. Guided format in answering this type of question

Find Manipulated Responding

1 HYPOTHESIS

Making relationship between the manipulated variable with respondingvariableEg:

The polar the manipulated, the polar the responding //If the polar manipulated so the polar responding//

Note: If the above sentence cannot be used:The manipulated variable can be split. The sentence must have manipulatedand responding variableEg: Macronutrients are needed for healthy growth of plants

Iron nail rust faster than steel nail 1 m

2 AIM OFEXPERIMENT To study the effect of .......Manipulated....... on / to ......Responding . 1m

3 VARIABLES (a) Constant : 1m(b) Manipulated: 1m(c) Responding : 1m

4 APPARATUSAND MATERIALS

Only the important apparatus and materials 1m

5 METHOD Diagram must be labelled (if drawn)Students must write the steps of the experiment

6 TABULATIONOF DATA

Draw table

Table must have:

4. Apparatus are left for . 1m If the student has no idea for

Section C - Experimenting

Find Manipulated :Mass of object

RespondingMotion of object

1 HYPOTHESISEg:The greater the mass of the object, the difficult the object to move //The more the mass of the object, the harder/difficult //If the mass is more , so the object is hard to move

1m

2 AIM OFEXPERIMENT To study the effect of mass of object on the motion of the object

1m3 VARIABLES (a) Constant : Size of tin// the height of tins hang 1m

(b) Manipulated: Mass of tin 1m(c) Responding : Motion of object/tin 1m

4 APPARATUSAND MATERIALS

Tins, rope/ string, sand, retort stand // any place to hang the tinsNote : Must have all 1m

5 METHOD

1. Prepare two tins with the same size and hung up using ropeat the same height - pt 1 (1 m)

2. Fill one tin with sand and leave the other tin empty -pt 2 ( 1 m)3. Push the tins (with the same force) at the same time-pt 34. The tin that is harder to swing is observed -pt4

6 TABULATION

OF DATA

7 CONCLUSION Eg:The greater the mass of the object, the difficult the object to move //The more the mass of the object, the harder/difficult

Mass of tin/object Motion of object

Less (empty tin)More (tin fill withsand)

The motion of an object is affected by its mass
