Section C : Experimenting STEPS 1. From the statement given, underline the words showing the manipulated and responding variable 2. Guided format in answering this type of question Find Manipulated Responding
Making relationship between the manipulated variable with responding variable Eg:
1 HYPOTHESIS
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 manipulated and responding variable Eg: Macronutrients are needed for healthy growth of plants Iron nail rust faster than steel nail 1m
To study the effect of .......Manipulated....... on / to ......Responding . 1m (a) Constant : 1m Max. 2m (b) Manipulated: 1m (c) Responding : 1m
4 APPARATUS AND
MATERIALS
5 METHOD
Note:
Steps explaining constant variable - 1m 2. Steps explaining manipulated variable - 1m 3. Steps explaining responding variable - 1m
If the result cannot be obtained at that particular time, remember to write this sentence
1m
Observation is recorded
- 1m
6 TABULATION OF DATA
Draw table MANIPULATE RESPONDING Table must have: D Title of table have Manipulated and responding Data LEAVE Data Manipulated MANIPULATED BLANK Data Responding not needed
1m 7 CONCLUSION
Write the conclusion of the experiment @ Rewrite the hypothesis sentence
1m
FORM 5 SCIENCE
Exercise Study the following statement. The motion of an object is affected by its mass You are given two tins with the same size and sand. (a) (b) Suggest a hypothesis to investigate the above statement. Describe an experiment to test your hypothesis in (a) based on the following criteria. (i) Aim of the experiment Identification of variables List of apparatus and materials Procedure or method Tabulation of data Conclusion Manipulated Responding [1 mark] [2 marks] [1 mark] [3 marks] [1 mark] [1 mark]
RESPONDING
7 CONCLUSION
FORM 5 SCIENCE
1 HYPOTHESIS
Eg: 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 To study the effect of mass of object on the motion of the object 1m (a) Constant : Size of tin// the height of tins hang 1m (b) Manipulated: Mass of tin (c) Responding : Motion of object/tin 1m
4 APPARATUS AND
MATERIALS
1m max 2 m Tins, rope/ string, sand, retort stand // any place to hang the tins Note : Must have all 1m

1. 2. 3. 4.
Prepare two tins with the same size and hung up using rope at the same height - pt 1 (1 m) Fill one tin with sand and leave the other tin empty -pt 2 ( 1 m) Push the tins (with the same force) at the same time-pt 3 The tin that is harder to swing is observed -pt4 maximum 3 marks
6 TABULATION OF DATAof tin/object Mass Less (empty tin) More (tin fill with sand) 7 CONCLUSION
Motion of object
1m Eg: The greater the mass of the object, the difficult the object to move // The more the mass of the object, the harder/difficult 1m
