TIPS UNTUK MENJAWAB KERTAS 3 BIOLOGY SPM.

Students must have all of the following :
-Problem Statement
-Aim Of Investigation
-Hypothesis
-Variables
-List Of Apparatus And Materials
-Technique Used
-Experimental Procedure Or Method
-Presentation Of Data
-Conclusion
1)PROBLEM STATEMENT
-what is the effect of MV with RV
-e.g : what is the effect of concentration of an external solution with length of potatoes ?
2)AIM OF INVESTIGATION
-to study the relationship between MV and RV
-e.g : to study the relationship between the concentration of an external solution and the length of potatoes.

3)HYPOTHESIS
-the higher/lower/decrease/increase  MV, the higher/lower/decrease/increase  RV.
-e.g : the lower the concentration of an external solution,the increase the length of potatoes.

4)VARIABLES
Manipulated - differences in the experiment
                      - e.g : the concentration of an external solution
Responding  - measurement
                      - e.g : the length of potatoes 
Fixed             - constant in whole experiment
                      - e.g : the initial length of potatoes/types of potatoes

5)LIST OF APPARATUS AND MATERIALS
-at least list down 3 materials and apparatus
-e.g : sucrose solution,freshly potatoes,distilled water,knife,petri dish,filter paper

6)TECHNIQUE USED
-what is observed or measured
-e.g : measure the length of potatoes with ruler 

7)PROCEDURE
-how to set up the apparatus
-how to make constant variable
-how to manipulate variable
-how to record the responding variable
-precaution

8)PRESENTATION OF DATA
-construct table with the correct tittles and units
9)CONCLUSION
-write hypothesis is accepted or rejected
-repeat or modifying the hypothesis sentences
-the hypothesis is accepted.the lower the concentration of an external solution,the increase the length of potatoes.
