PAPER 2 : SECTION A & C(Based on EXPERIMENT)

SCIENCE PROCESS SKILLS( 12 elements )

OBSERVATION ( O = MV+RV) INFERENCE ( I = O+Why) HYPOTHESIS ( H = MV+RV relationship) VARIABLES (MV,RV,CV) CLASSIFY MEASURE & USING NUMBER RELATIONSHIP SPACE & TIME COMMUNICATION ( graph/table/diagram) ANALYSE DATA PREDICT OPERATIONAL DEFINITION ( OD= Q is ……. O/RV) EXPERIMENTAL ( Section C No.10)


1. OBSERVATION1. What can your observe about the the plasticine block after the collision?

(Q: 4(b)(i)) SPM20072. Observe Diagram 2.1 and 2.2. Compare the focal lengths between two convex lens. SPM 2008


answerOBSERVATION

O = MV + RVTrolley Q (MV)

produceddeeper dent on the plasticine (RV)

(compare to the trolley P)


2. INFERENCE1. State one inference that can

be made based on the observation. Q:4(b)(i) SPM 2007

2 State one inference for this experiment


AnswerINFERENCE

I=O +becauseTrolley Q produced deeper dent (O)

becausetrolley Q has bigger

mass/momentum


3. HYPOTHESIS1. State the hypothesis based

on this experiment Q: 2b spm 2007 Q: 4c spm 2007


AnswerHYPOTHESIS

H=MV+RV 1.The further the distance of object (MV)

the smaller the size of image (RV)2.The bigger the mass (MV) the deeper the dent on the plasticine (RV)


4. VARIABLES 1.State the variables in this experiment (i) Sentences Example: …to study the effect of pH value on the growth of bacteria MV RV

Q: No 3 spm 2007


(ii) Table MV RV


pH value

Cloudiness of mixture

Less than 7

Slightly cloudy

More than 7

pH7

(iii) Graph


Time MV

Volume of hdyrogen gas

RV

CONSTANT VARIABLES (CS)(i)From statement ….Q: 1 spm 2007

(ii)From diagram…Q: 2,3,4 spm 2007

Find the answer !!!


5. CLASSIFY1. Tick (/) in the boxes the

substances which can be used to replace magnesium . Q: 1c spm 2007

2. Give two characteristics of the image in Diagram 2.2. Q: 2d spm 2007


6. MEASURE and USING NUMBER1. Measure and write down the

size of the image formed in Diagram 2.1

Q: 2a spm 20072. What is the final reading of the

thermometer in Diagram 1.2? Q: 1b spm 2008


7.SPACE and TIME RELATIONSHIP

1. Based on the graph in 1(a), state the relationship between the volume of hydrogen gas and time in the first 90 seconds. Q: 1b spm 2007

2. What is the relationship between the height of seedling and time? Q: 3c spm 2008


answerSPACE & TIME RELATIONSHIP


Time

Volume of hdyrogen gas

When the TIME increased ,the VOLUME OF HYDROGEN GAS increased

8. COMMUNICATION1. Based on Table 1.1, draw a

graph of the volume of hydrogen gas against time.

Q: 1a spm 20072. Using the data in Table 3, draw

a graph of the height of the seedling against time Q: 3b spm 2008


answerDRAWING GRAPH

(i) HISTOGRAM/BAR CHART

(ii) LINE GRAPH


9. ANALYSE DATA1. Based on Table 3, what is the

best condition for the growth of bacteria?

Q: 3b(i) spm 20072. Based on the graph, state the

optimum temperature for bacterial growth.



Time

Temperature

40 0C

10. PREDICT1. Predict the size of the image if object P is placed at 10 cm from the pin hole camera. Q: 2c spm 2007

2. Predict the height of seedling on the 10th day. Q: 3d spm 2008


11. OPERATIONAL DEFINITION

1. Based on this experiment state the operational definition for bacterial growth Q: 3c spm 2007

2. What is the operational definition of distilled water? Q: spm 2003

3. State the operational definition of fermentation. Q: 4d spm 2008


answerOPERATIONAL DEFINITION

1. Based on the result in Table.

Bacterial growth(Q) is a process which cause the

cloudiness of mixture become very cloudy at pH 7 (O/RV)


pH value

Cloudiness of mixture

Less than 7

Slightly cloudy

More than 7

Slightly cloudy

pH7 Very cloudy

2.

Distilled water is a substance which has

boiling point 100 0 C BENGKEL SAINS SPM 2010

Substances Boiling point /

0CDistilled water 100Distilled water + common salt

3. From the Diagram.

30 0 C

Fermentation is a process which gas P is collected at 30 0 C.
