8. LEARNING SCIENCE PROCESS SKILLS THROUGH THE WRITTEN EXAMINATION PAPER

11. (a) (Your answer should be based on what you can see from the diagram only. Look at the needle of the ammeter, what can you see?. Write your answer) Answer : Needle deflects (b) ( Read the reading of the ammeter, then write your answer) Answer : 0.4 A

14. 3. USING TABLE OF THE RESULT First column Second column (Manipulated variable) (Responding variable) 4. USING GRAPH Y Axis : Responding Variable Y Axis : Manipulated Variable

15. (e) State one inference for this experiment (Refer to the result of the experiment. In this case, an ammeter reading in Diagram 1.1 and 1.2 Give a reason why such results are obtain. Your reason will be an inference) Answer : Answer : Solid lead (II) bromide cannot conduct electricity OR Molten lead (II) bromide can conduct electricity

16. (f) State the hypothesis that can be made from this experiment ( Relate the manipulated variable with the responding variable and form one complete sentence ) Answer : Different state of lead (II) bromide give different ammeter reading OR The electrical conductivity of different state of lead (II) bromide is different

17. What you want to define (g) Lead (II) bromide is an ionic compound. State the operational definition for an ionic compound Answer format : …………… is a ………. that show / caused / produced …………………… Answer : (Ionic compound) is a (substance) that (caused) (deflection on the ammeter’s needle in molten stage) Using suitable term / word Choose any one Result of the experiment

18. ( h) Mark ( ∕ ) the substances which have same characteristic as lead (II) bromide (This is a question based on comparison of similarities (classifying question) Determine which substance has the same characteristic as lead bromide, which can only conduct electricity in molten stage. Then mark ( ∕ ) at the correct space . Answer : Mark ( ∕ ) for sodium chloride Sodium Chloride Sulphur Copper

20. (This is one type of question based on communicating . Your must show the rays diagram and the image formed by the concave lens in the diagram ) Your diagram must include : (i) Two light rays with arrows (ii) Correct image drawn in dotted line Answer :

21. (b) Measure and write down the distance of the image ( Measure the image using your own ruler) Answer : 1.2 ± 0.1 cm (c ) State two characteristics of the image formed in 2 (a) (This question requires interpreting of the data. Determine two characteristics of the image) Answer : 1. Virtual 2. Upright 3. Smaller than the object

22. (a) Using data in Table 3, draw a graph of the number of bacterial colonies against Time. (This question requires the transfer of information.

23. Mark all points correctly using ‘x’. Then draw a smooth line graph. The graph must joint all the points. Do not use a ruler to draw the graph. Use a pencil only) Answer :

24. Refer to the Y axis of the graph. What does it represents. Copy the unit of Y axis (b) What is the relationship between the number of bacterial colonies and time? Format answer: ( When the time increase, the ………….. increases / decreases) Answer : When the time increases, the number of bacterial colonies increases

25. (c) Predict the number of bacterial colonies produced on the 6th day. ( Continue drawing the graph from day five to day six with a pencil. Than determine the reading or value from the graph. After that, you must rub off the extrapolated part of the graph that you drew from minute five to minute 6) Answer : 22

26. Study the following statement . You are given an iron nail, a steel nail and sodium chloride solution Experimenting aspect An alloy and pure metal have a different corrosive resistance characteristic

27. (a) Suggest a hypothesis to investigate the above statement (Refer to the previous section)

28. (b) Aim of the experiment (Derrive from the statement in the box. If it cannot be done, just put the words “ To study whether” in front of the statement . Answer: To study whether an alloy and pure metal have a different corrosive resistance characteristic

29. b(ii) Identification of variables ( Refer to the previous section)

30. b(iii) List of apparatus and material (List down all the apparatus and materials given. Then add another one or two apparatus needed to ensure the success of the experiment)

32. b(v) Tabulation of data (Construct a table. The title of each column is the manipulated variable and responding variable. Information for manipulated must be detail and complete. No need to write information for responding variable) Steel nail Iron nail Corrosive condition / rusting Type of nail
