1. Diagram 1.1 and 1.2 show an experiment to study the electrical conductivity of lead (II) bromide

(a) Based on Diagram 1.2 , what is your observation on the needle of the ammeter?

(b ) What is the reading of the ammeter in Diagram 1.2?

(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

(c ) State the variables in this experiment.

(i) Constant variable :

( Determine which factor of the substance (lead (II) bromide) is the same / fixed in both Diagram 1.1 and 1.2 )

Answer : Quantity of the substance / lead (II) bromide

(ii) Manipulated variable : ( Determine which factor of the substance (lead (II) bromide) is different / changed in both Diagram 1.1 and 1.2 )

Answer : State of the substance / lead (ii) bromide

(iii) Responding variable : (Refer to the statement given in the question. Determine the aim of the experiment. The aim of the experiment is the factor that we want to find out from the experiment. It will be the responding variable)

Answer : Electrical conductivity // Reading of the ammeter

1. USING STATEMENT OF THE QUESTION

to study ……………………… by / on ……………………….. ( responding variable) ( manipulated variable)

2. USING DIAGRAM

Different factor/condition Factor/ result needed( manipulated variable) ( responding variable)

Factor which is same in the DIAGRAM or stated same in the QUESTION’S STATEMENT is a constant variable

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

(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

(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

ORThe electrical conductivity of different state of lead (II) bromide is different

Using suitable term / word

Choose any one

Result of the experiment

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)

(h) Mark ( ∕ ) the substances which have same characteristic as lead (II) bromide

CopperCopper SulphurSulphur Sodium ChlorideSodium Chloride

(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

2. Diagram 2 shows an experiment to study the formation of an image by a concave lens.

(a)Complete Diagram 2 to show the formation of the image by the concave lens.

(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 :

(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. Virtual2. Upright

3. Smaller than the object

(a) Using data in Table 3, draw a graph of the number of bacterial colonies against Time.

(This question requires the transfer of information.

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 :

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

(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

Study the following statement.

An alloy and pure metal have a different An alloy and pure metal have a different corrosive resistance characteristiccorrosive resistance characteristic

You are given an iron nail, a steel nail and sodium chloride solution

Experimenting aspect

(a) Suggest a hypothesis to investigate the above statement

(Refer to the previous section)

(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

b(ii) Identification of variables

(Refer to the previous section)

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)

b(iv) Procedure or method

Write down a minimum of four steps.

The steps must consist:

1. set up / arrangement of apparatus / material 2. duration of time3. observe and record the result4. repeating of the experiment

( Your answer must be in Present Tense)

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)
