SCIENCE ANSWERING TECHNIQUE FOR SECTION B 1.CONTROLLING VARIABLES a. THINGS TO KEEP THE SAME / CONSTANT / FIXED - the same thing ( The type of……./ Same type/size of…..) b. THING TO CHANGE (T2C)/ MANIPULATED / INDEPENDENT - different / not the same ( The size/shape of…../ The presence of…..) c. THING TO MEASURED (T2M)/ RESPONDING / OBSERVED / DEPENDENT - the results / findings ( The conditions / numbers of……) 2. OBSERVATION ( Plant A has many leaves than Plant B ) 3. INFERENCE ( Plant A has many leaves because it get more water than Plant B ) → State another observation to support your inference ( Plant A has big leaves/ stem ) 4. AIM / PURPOSE → To investigate the relationship between T2C with / and T2M ( To investigate the relationship between size of ice with the time taken to melt ) 5. HYPHOTHESIS / RELATIONSHIP (pattern) (pattern) → The…………………..(T2C), the…………………....(T2M) (The bigger size of ice , the longer the time taken to melt) →The higher/ the lower , The bigger/ the smaller , The longer/ the shorter, The increase / the decrease, The more/ the least, The thicker/ the thinner → When…(MV)… (pattern)………,the….(RV)…….(pattern)……. → If……(MV)…(pattern)……..the…..(RV)………will……(pattern)….. 6. CONCLUSION →When size of ice big , the time taken to melt is long →The most/greatest number of flower produced when the temperature is at 35°C to 45°C 7. TREND / PATTERN → 2, 4, 6 } increase → 6,4, 2 } decrease → 5, 5, 5 } constant/ same / unchanged

Respond Variable Manipulated Variable
QUESTION SHAPE SHOULD KNOW CONSTANT VARIABLE Examples: 1. WHAT TO / WAS / IS KEPT THE SAME ? MANIPULATED VARIABLE Examples: 1. WHAT TO / WAS / IS BE CHANGED ? RESPONDING VARIABLE Examples: 1. WHAT TO OBSERVE / MEASURE? TWO VARIABLE Examples: 1. STATE TWO VARIABLES IN THIS INVESTIGATION THREE VARIABLES Examples: 1. STATE THE FOLLOWING A. MANIPULATED VARIABLE B. RESPONDING VARIABLE C. CONTROLLED VARIABLE AIM / PURPOSE Examples: 1. WHAT IS THE AIM OF THE EXPERIMENT / INVESTIGATION ? 2. WHAT IS THE PURPOSE OF THE EXPERIMENT / INVESTIGATION ? 3. STATE THE AIM / PURPOSE THE INVESTIGATION / EXPERIMENT. INFERENCE Examples: 1. GIVE THE REASON 2. STATE WHY ? HYPOTHESIS / CONCLUSION / RELATION Examples: 1. WHAT IS THE HYPOTHESIS OF THE INVESTIGATION? 2. WHAT IS THE HYPOTHESIS OF THE VARIABLE? 3. WHAT IS THE RELATION BETWEEN THE VARIABLE? 4. WRITE ONE HYPOTHESIS BASED ON ………………….. 5. STATE THE RELATIONSHIP BETWEEN MANIPULATED VARIABLE AND RESPONDING VARIABLE. 6. WHAT IS THE CONCLUSION CAN BE MADE? 7. STATE ONE CONCLUSION 8. WRITE ONE STATEMENT RELATING THE TWO VARIABLES 9. WHAT CAN YOU SAY……….MV……… AND ………RV………ON THIS INVESTIGATION? PATTERN / TREND Examples: 1. WHAT IS THE TREND OF CHANGE IN THE NUMBER OF…………… 2. WHAT IS THE PATTERN OF CHANGE IN THE……………
