MAKING INFERENCE/ MEMBUAT INFERENS

• Using information from observations to make reasonable early conclusions.
• Menggunakan data dari pemerhatian untuk membuat penerangan awal.

• Making various possible interpretations from single observation
• Memberikan pelbagai andaian dari pemerhatian tunggal

• Using inferences as a tool to determine the appropriate additional observations.
• Menggunakan inferens sebagai alat untuk mengenalpasti pemerhatian tambahan yang jitu

• Testing the accuracy of inferences through additional observations.
• Menguji ketepatan inferens melalui pemerhatian tambahan

• Give reason to an observation or making an earlier conclusion from what have been observed.
• Memberikan sebab kepada pemerhatian yang telah dibuat

The Inferences/Menginferens

• Logical inference – any reason as long as it is logic.
• Inferens logik- sebarang sebab yang logik

• Comparing – any logical reason but the answer must be in a form of comparing.
• Bandingan – sebarang sebab yang logik dalam bentuk bandingan

• Controlled/exact – only one specific reason is accepted.
• Jitu – hanya satu jawapan sahaja

Examples of questions

• State two reasons based on the observation above.
• State an inference for the condition of the fish in the aquarium.
• Give a reason for the answer given in (a)
• Why is the distance of the moving trolley decreasing?
  
  
• CONTROLLING VARIABLES/ MENGAWAL PEMBOLEH UBAH
  
  
  The Variables/ Pemboleh ubah-pemboleh ubah
  
  
  1. What to change (wc) / yang berubah
  2. What to observe/measure (wm) / yang diukur/ diperhatikan
  3. What to keep the same (same)/ yang sama
  
  
  1. What to observe/measure
     
  -          Thing that is being observed / measured /investigated / recorded / the result of an
        investigation.
  
  
  2. What to change (tc)
       
  -          Thing that is changed or being manipulated in an investigation and it has an effect on
        thing that is observed.
  
  
  3.  What to keep the same
      
  -          Thing that is always the same and kept constant in an investigation.
  
  
  
  Interpreting Data/ mentafsir maklumat
  
  
  The questions based on the
  n        Table
  n        Graph
  n        Bar chart
  n        Diagram
  
  
  To state:
  Ø       The aim/purpose of the investigation
  Ø       The trend or pattern of the data given
  Ø       The relationship between the thing to change and thing to observe.
  Ø       By making conclusion or what you have learnt
  
  
  Aim / Purpose of the investigation or things to find out.
  
  
  Examples of questions
  
  
  •      What is the aim/purpose of the investigation above?
  •      What have you found out from the investigation?
  •      State the purpose of the investigation.
  •      What is/ state the aim of the investigation/experiment/ fair test
  •      What is/ state the purpose of the investigation/ experiment/ fair test
  •      What are you going to find out?
  
  

  The Sentence/ Cara Menjawab

  
  

  Ø       To investigate the relationship between..(what to change)..and ..(what to observe)….

  Ø       To find out the effect of ….(what to change)…on/to ….(what to observe)…./

  Ø       Mengkaji hubungan di antara ……… yang berubah …… dan …….yang diukur…..

  Untuk mengkaji kesan ……..yang berubah ….. terhadap/ kepada ….. yang diukur
  

  
  

  PREDICTING/MERAMAL

  
  

  • Stating the outcome of a future event based on prior knowledge gained through experiences or collected data.
  • Able to determine the outcomes from an action.
  • Using pattern of data explicitly to make projections.
  • Confident with the accuracy of the prediction.
  • Able to verify a statement of related to future events based on evidence or past experiences.
  • Extrapolating and  inserting data as a tool to predict

  
  

  
  

  Two ways to make prediction.

  1. Based on the calculation from the data given. Answers obtained from the calculation is always exact (one whole number)

  
  

        2.   If the answer obtained is not exact or in range, write down only one whole

              number from that range

              Note:  Depends on the questions.

  
  

  Examples of questions

  
  

  • Predict the length of the string if a 5 kg load is used
  • Predict in which pot the seeds will grow the healthiest.
  • Predict the condition of the animal in container B after 2 weeks.
  • What will happen to the plant if it is covered with a box?
    
    
    
    MAKING HYPHOTESIS/ MEMBUAT HIPOTESIS
    
    
    Hypothesis:
    
    
    Making a statement of which can be proven by doing an experiment or investigation or fair test
    
    
    Hypothesis sentence
    
    
    Examples:
    n        The more the time taken to heat the water, the more the temperature is.
    n        As the time taken to heat the water increases, the temperature also increases.
    n        The longer the string, the lesser the number of swings.
    n        Plants need water to grow well
    n        If the type of objects are different, the ability to absorb of water also different.
    
    
    
    
    Examples of questions
    
    
    a)      State a hypothesis based on the investigation above.
    
    
    b)      What is the hypothesis of this investigation?
    
    
    c)      Write a hypothesis based on the information above.
    
    
    
    
    
    
    Technique of answering:
    
    
  • …..( trend/pattern)….  …(wtc)…..,  ……(trend pattern )……  ……(wto) ………

  
  

  2.    As/If/When  ......(wtc)….  ….(trend/pattern)….,  ….(wto) … also  …..(trend/pattern)….

  
  

  
  

  
  

  
  

  Clue:   1.  Identify the WTC and WTO

              2  Identify the trend/pattern of the WTC and WTO (if any)

              3..Relate the WTC and WTO to form hypothesis sentence
