ANSWERING TECHNIQUES SCIENCE PAPER 2 by HUZAINI ISMAIL

#Suitable for DLP Class

Define Variables

What to change / WTC (manipulated variable)

What to observe/ measure/ WTO (responding variable)

What to keep the same / WTS (constant variable)

Example 1

Example 2

Example 3

Aim of investigation (what to find out)

Keyword: To investigate the relationship between WTC and WTO or 

                  To find out the relationship between WTC and WTO

#investigate = study

Observation

#use 5 senses to observe what happen to the situation

Example 

Observation; In year 2012, the number of endangered animals is larger than year 2000.

Trend

• ·         Increase
• ·         Decrease
• ·         Constant
• ·         Increase and decrease
• ·         Decrease and increase

# trend based on the data given (table, graph, chart)

Example 1

Example 2

Example 3

Example 4

Hypothesis/Relationship

Relate between WTC n WTO

Keyword : The more/ the lesser  WTC, the more/the lesser WTO or

                  As the WTC trend, the WTO also trend


#replace WTC, WTO n trend with suitable answer

ALSO can be used

The bigger/ the smaller
The longer/ the shorter 
The thicker/ the thinner
The more/ the least 

Prediction

#predict what will be happen

Inference

#give reason for any situation (why something happen)

Conclusion

#conclude based on the observation

#same answer with hypothesis also can be accepted 

keyword: When/as WTC trend, the WTO trend

Let try it…

Table shows the information collected by a group of students in an investigation

a) What is changed?

    Year

b) What is observed?

     Number of endangered animals

c) What is to keep the same?

   Place of investigation, type of animals

d)What is the aim of investigation?

    To investigate the relationship between year and number of endangered animals

e) What is the relationship between two variables?

    The more year, the more number of endangered animals

f) What is the trend of number of endangered animals?

    Increase

g) Predict the number of endangered animals in year 2014?

     1000

h) Give your inference based on answer given in (g)

    The number of endangered animals are increase because illegal hunting.

i) What can you conclude from this investigation?

   The more year, the more number of endangered animals
