PAPER 3 : QUESTION 1 1. MEASURING AND USING USING NUMBERS NUMBERS
Complete he table by recording the reading of thermometer, thermometer, stopwatch, stopwatch, measuring tools , ruler etc. from the given diagram. (state the unit if it is not stated in the header of table)
2. OBSERVATION
QUESTION : State two observations…. ANSWER : Write -
down what can be observed only . Usua Usuall lly y hav havee uni units ts and and val value uess Link Link MV MV and and RV RV as as show shown n in the the head header er tabl tablee Do not not do the the anal analys ysis is,, compar compariso ison n or concl conclusi usion. on.
3. INFERENCE
State one scientific explanation which corresponds to each observation
4. COMMUNICATING
Construct the table using the given titles and units, record the relevant data or calculation.
5. INTERPRETING DATA
State the relationship and explain
6. VARIABLES
Manipulated variable – 1st column of table/from question Responding variable – 2nd or 3rd column of table/ from question Fixed variable – find from question (1 is enough)
Method to handle the variables (MUST USE VERB and state the INSTRUMENT used)
MANIPULATED
Use di different …
RESPONDING
Measure RV using apparatus and record (Observe/ read/ are not accepted) Use th the sa same…/ Ma Mainta ntain … at….
CONTROLLED
7. MAKING HYPHOTHESIS
Able to state the the hypothesis correctly based on the following criteria:
State the manipulated variable (MV) State the responding variable (RV) State the relationship between MV and RV
8. PREDICTING
QUESTION : If the experiment is repeated ….., predict the observation …… ANSWER : One number or relevant statement -increase -decrease -same/constant -more than -Less than X more or less 9. DEFINING OPERATIONALLY
EXAMPLE: Based on the the results of the experiment, what can you deduce about vitamin C ? YOUR ANSWER MUST BEGIN WITH : Vitamin C is ….. (Your answer must based on the results of the experiment, not exactly from the theory. Must also include the RV and MV) e.g. Vitamin C is the ascorbic acid which can decolorize the DCPIP solution and it is found in different types of fruit juice.
Students must complete the given table according to the title. If the table is not provided, construct the table table according to the classification given given . 11. USING SPACE-TIME RELATIONSHIP
State the changes of … with time
PAPER 3 : QUESTION 2 (New Format in SPM 2010) Students must have all of the following: Problem statement Hypothesis Variables List of material and apparatus Experimental procedure or method Presentation of data
1. PROBLEM STATEMENT(3M)
Must be in a question form. (What/how/is/does the MV…..RV?) 2. HYPOTHESIS(3M)
Able to state the hypothesis correctly based on the following criteria: State the manipulated variable State the responding variable Relate the MV and RV Higher………..higher/ lower Bigger……….. bigger/smaller More………… lesser 3. VARIABLES(3M)
Manipulated variable: Responding variable Fixed variable: (1 is enough)
List down at least 5 apparatus . MATERIALS (can be used only once)
List down at least 3 materials
5. PROCEDURE / METHOD METHOD (3M)
Write down each step clearly and systematically (include precautionary steps ) . K1: technique of assembling the apparatus to carry out the experiment K2: technique of fixing the FV K3: technique of changing the MV K4: technique of measuring the RV K5: precautionary method to increase accuracy/formula
6. PRESENTATION OF DATA (2M)
Construct the table with the correct titles and units (results (results – no need to fill, just leave it blank).
