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.
