SCIENTIFIC SKILLS SCIENCE PROCESS SKILLS MANIPULATIVE SKILLS Observing Using and handling science apparatus Classifying Maintaining science apparatus correctly and safely Measuring and using numbers Making inferences Cleaning science apparatus correctly Predicting Communicating Handling specimen correctly and carefully Using time and space relationship, Interpreting data, Define operationally, Controlling variables, Making hypothesis, Experimenting Sketch specimen and science apparatus

How a scientist works, thinks and studies problems. (Friedl, 1995)

A way of investigation that involves specific skills which require the following steps: Planning course of actions Carrying out activities Collecting data Organising and interpreting data Reaching a conclusion

OBSERVING CLASSIFYING MEASURING AND USING NUMBERS MAKING INFERENCES PREDICTING COMMUNICATING For you information, actually there are are 12 SPS in science curriculum. But at aor level, we will concentrate on only 6 of them. They are :……….. The other 6 are : The relation between space and time. Interpreting data. Definition by operation Controlling variables Hypnotizing Experimenting


6 OBSERVING Specimen given: Groundnut Activities:
Individually, examine the specimen given. Record its characteristics. iii. Put the specimen back into the box and mix the groundnut up. iv. Try to identify your specimen based on the characteristics recorded earlier.

7 You are observing when you are …

8 Using the five senses effectively.

9 2. Identifying relevant particulars of an objects and its environment.

10 3. Focusing on relevant particulars from massive information.

11 4. Identifying similarities and differences.

12 5. Identifying strange / unusual features.

13 6. Realizing changes in environment.

14 7. Identifying the correct sequence.

15 8. Using appropriate instrument(s) to enhance senses for the details.

16 What is meant by observing ?
Observing involves collecting information about objects or phenomenon by using the five senses : Sight Hearing Touch Taste Smell Whatever we have done earlier is about observing. It is one of the six SPS that we are going to cover, Are you ready to move on the second SPS

17 Why do we need to observe?
To compile / gather as much information as possible about objects or phenomena.

18 How do we observe? Focus on the objects or phenomena to be studied.
Identify the characteristics. Compare the objects or phenomena. Identify changes and sequence of events. Use appropriate apparatus for more detailed observations.


20 You are classifying when you are….


22 Detecting similarities .
Same shape Same Colour

23 2. Grouping objects based on certain criterion.

24 3. Using other criterion in grouping objects.

25 4. Grouping objects in different ways.

26 What is meant by classifying?
Classifying is a process of grouping objects according to certain characteristics for a purpose.

27 When do we need to classify?
When there are : Many items or information. Items or information are not organised.

28 How do we classify? Identify the general characteristics of the items.
Sort out items of the same characteristic into their respective groups. Identify other characteristics. Repeat steps 1-3 until there is only one item in each group.


30 You are measuring and using numbers when you are….

31 Able to count and compare quantity of items in different groups.
= 1 = 3 = 5

32 Able to count and compare quantity of items in different groups.
= 4 = 6

33 2. Able to recognized the pattern from a table of numbers.
20 , 25 , 30 , 35 10 , 20 , 40 , 80 120 , 95 , 79 , 70

34 3. Using numbers to record phenomenon.

35 3. Using numbers to record phenomenon.
3 cm 4 cm 5 cm Hari 1 Hari 2 Hari 3

36 4. Using scales and explaining ratios.
1 cm : 10 cm

37 5. Compare objects using numbers.
RM 17.00 RM 18.00 1600 cc 2000 cc

38 6. Using tools correctly.

39 7. Recording unit correctly.
ml m c o ? g kg cm 3 km cm

40 8. Choosing and using standard unit.
km cm ? mm m

41 9. Comparing time, distance, area and volume with relevant units.
20 minutes 50 minutes 7 km 19 m

42 I have been reading for 2 hours
10. Determining the accuracy in measurements. I have been reading for 2 hours I have waited for 2 moons Which is more accurate?

43 What is meant by measuring and using numbers?
Measuring and using numbers is a process of observing quantitatively using numbers and standard or standardised measuring tools as the reference unit. Standard tools – established tools such as rulers, measuring tapes, measuring cylinders (Tools which are used established or accepted universally) STANDARDISED TOOLS – tools which can be used for measuring an object quantitatively using unit which is not established/ accepted universally such as cup, “jengkal”, hasta..etc

44 Why do we need to measure and use numbers?
To obtain more accurate observations.

45 How do we measure and use numbers?
1. Identify the measurement required. 2. Specify the instrument to be used. 3. Compare the measurement with the specific instrument. 4. Add up the total measurement.


47 You are making inferences when you are ….

48 Using information from observations to make reasonable early conclusions.

49 2. Making various possible interpretations from single observation.

50 3. Able to identify the limitations of inferences.

51 4. Testing the accuracy of inferences through additional observations.

52 5. Using inferences as a tool to determine the appropriate additional observations.

53 Why do we need to infer? To plan actions or to make a choice.
2. To analyse the cause and effect of decisions Using the inferences , we can determine what action should be taken ( throw away / keep ) Based on the decision made , what are the effects ? ( Unable to cook / stomach-ache )

54 How do we infer? Observe the situations or circumstances.
State the reason why the situation or circumstances happens . Give reasons to your statement(s). Check if the reasons given are based on opinions or observations from the situations. If based on opinions, state why.

55 What is meant by making inferences?
Making inferences is a process of making early conclusions by relating previous experiences with immediate observations.


57 You are predicting when you are……….
Using previous or present evidence to state incoming events. 2. Able to differentiate between predicting and guessing. 3. Able to determine the outcomes from action. 4. Using pattern of date explictly to make projections.

58 You are predicting when you are….
5. Confident with the accuracy of the prediction. 6. Able to verify a statement of related to future events based on evidence or past experiences.

59 You are predicting when you are….
7. Being cautious in making assumption about a certain pattern of data beyond the evidence at hand. 8. Extrapolating and inserting data as a tool to predict.

60 Why do we need to predict?
When accuracy is not essential in: Reducing the number of choice. Planning Considering choices Example : The prediction of which beans will germinate will help reduce the numbers of bean sown.

61 How do we predict? Observe to gather data.
Identify the pattern of the data. Based on the pattern or past experiences, make suitable predictions.

62 What is meant by predicting?
Predicting is a process of forecasting events based on observations and previous experiences or certain pattern of reliable data.


64 You are communicating when you are….
Speaking, listening or writing to express ideas or meanings. 2. Recording information from investigations. 3. Drawing and making notes. 4. Using and explaining the meaning of symbols.

65 You are communicating when you are….
5. Using charts, graphs and tables to present information. 6. Posting questions clearly. 7. Using references. 8. Writing experiment report to enable others to repeat the experiment.

66 Why do we need to communicate?
To spread ideas or information. To share ideas or information.

67 How do we communicate ? Record information obtained from various resources. Translate the information into other forms such as charts, graphs and tables. Spread the information through various means and ways.

68 What is meant by communicating?
Communicating is a process of receiving, spreading and sharing of information and ideas.
