1. PROBLEM STATEMENT
|
Tip : In question form relating the manipulated variable (MV) and the responding variable (RV).
(Must have question mark)
Eg: What is the effect of (MV) on the (RV)?
|
2. HYPOTHESIS
|
Tip: A statement stating the relationship between MV and RV.
Eg : The higher the MV, the higher /lower the RV
|
3. VARIABLES
|
Tip : Manipulated variable - this variable is being changed in this experiment.
Responding v - this is being measured in this experiment.
Fixed/Constant v - these are factors being kept constant throughout the experiment.
|
4. LIST OF MATERIAL AND
APPARATUS
|
Tip : Material : Things that can only be used only once; eg, solutions.
Apparatus : Things that can be reused again and again. Eg: beakers, test tube.
|
5. EXPERIMENTAL PROCEDURE
|
Tip :
1. Steps where you describe how apparatusand materials are handled (Setup of the expt).
2. Steps where you describe how the controlled/fixed variable is maintained.
3. Steps where you describe how the manipulated variable is altered.
4. Steps where you describe how the responding variable is measured and the instrument to be used.
5. Precautions.
|
6. PRESENTATION OF DATA
|
Tip : In table form with titles and units.
(The experiment has not been carried out yet,
so the results are not yet available).
