SCIENCE PROCESS SKILL (SPS) 1.Observing 2.Classifying 3.Measure using numbers 4.Makin Inference 5.Predict 6.Communicate 7.Using time space 8.Interprete data 9.Operational definition 10.Controlling variables 11.Making Hypothesis 12. Experimenting
1. READ AND UNDERSTAND THE QUESTIONS 2. FIND THE HEART OF THE QUESTIONS
VARIABLES MANIPULATED (MV) = FACTOR CHANGED RESPONDING (RV) = FACTOR OBSERVED CONSTANT (CV) = FACTOR FIXED
MANIPULATED VARIABLE (CV) THINGS / OBJECT / DIFFERENT SITUATION FACTOR THAT IS CHANGE?
RESPONDING VARIABLES (RV) RESULT / OBSERVATION TRV ORV Theory/ Science concept FACTOR THAT'S BEING OBSERVE? Experiment • Measuring tools • Changes in substance
CONSTANT VARIABLES (CV) SAME / NO CHANGE FACTOR THAT IS FIXED?
HOW TO IDENTIFY VARIABLES? 1.Graph 2.Table 3.Diagram 4.Question's statement
1 Graph mv Gas volume (cm3) time (s) rv
Type of nail Condition of nail Iron nail Turns to brown Steel nail No changes orv 2 Table mv
Concentration of thiosulphate(mol dm-3) 0.25 0.20 0.15 0.10 0.05 Time take for 'X' to dissapear (s) 20 23 35 46 48 2 Table mv orv
3 Diagram Moist bread Dry bread Black spot mv rv cv
4 Question's statement Experiment conducted to study the relationship between MV and RV Experiment to study therelationship between size ofsubstanceandrateofreaction
4 Question's statement Experiment conduct to study the effect of temperature on the growth of microorganism Experiment conduct to investigate the corrosion's resistance of alloy and pure metal
HYPOTHESIS GENERAL 1. 1. The MV, The ____ RV. 2.If MV , Then RV . FACTS 1. MV1 have RV than MV2 RELATION OBSERVATION INFERENCE Observation (ORV) + because + (MV) + RV (THEORY) OPERATIONAL DEFINITION Increase/decrease/ more/less/higher/ lower 1 Last word (Underline) 2 is a 3 substance/process/condition 4 that is shown by// that is produced 5 ORV (from experiment) 6 when 7 CV
OBSERVATION 1. Answer must comes from diagram/table that can be seen OR result (ORV) 2. General observation: Comparison of result of experiment 3. Specific observation : Comparison of result based on diagram given
INFERENCE 1. Give EXPLANATION towards OBSERVATION 2. Explain the result of experiment FORMULA: Observation (ORV) + because + reason (MV) + (TRV) INFERENCE = REASON/CAUSE
OBSERVATION Iron nail have rust but steel nail does not. INFERENCE Iron nail have rust but steel nail does not because Iron nail does not have resistance towards corrosion
OBSERVATION Theclearareaforantibioticdiscthathavehighconcentrationisbiggerthanantibiotic discwithlowerconcentration INFERENCE Theclearareaforantibioticdiscthathavehighconcentrationisbiggerthanantibioticdisc withlowerconcentration because High concentration of antibiotic Killsmorebacteria//inhibitthegrowthofbacteria
HIPOTESIS
OPERATIONAL DEFINITION SUITABLE WORD OPERATIONAL DEFINITION Substance Alloy, Metal, Nutrient agar, Distilled water, Latex, Culture solution, Simple Chemical Cell Condition Inertia, Pressure, Temperature, Pulse rate, gravititional Force, Free fall Process Alloying, Growth, Vulcanisation, Polimerisation Value/ Measurement / Numbers / Rate of reaction , Calorific value, Pulse rate Principle Bernoulli, Pascal
WHAT TO DO FOR SECTION A 1. READ through the question. 2. UNDERLINE the sentence 'TO STUDY ..... / TO INVESTIGATE ......... ' until fullstop 3. IDENTIFY MV and RV (and CV if given) in th sentence - if not given, find from TABLE / GRAPH
4. READ all the questions 5. VARIABLES: COPY directly what is given 6. OBSERVATION : ONLY give what you can SEE/MEASURE from diagram given 7. HYPOTHESIS : 3 WAYS to build hypothesis (MV must comes first, then only RV)
7. HYPOTHESIS : 3 WAYS to build hypothesis (MV must comes first, then only RV) - The _________ MV, the ________ RV - If MV ________, then RV ___________ - FACTS FORM
HYPOTHESIS :
PREDICTION : TIPS * Have to refer to data given in table
EXAMPLE 1:
8. RELATIONSHIP : Comes from Graphs - almost the same as HYPOTHESIS 9. GRAPH : - plot ALL correct = 1m - Graph neat, smooth = 1m 10. Operational Definition : - UNDERLINE the last word in question - The last word should be the FIRST word to starts your answer _________ is a substance/process/condition that is shown by RV in (constant variables)
RELATIONSHIP : Use what is being ask - almost the same as HYPOTHESIS
Operational Definition : - UNDERLINE the last word in question - The last word should be the FIRST word to starts your answer _________ is a substance/process/condition that is shown by RV in (constant variables)
11. INFERENCE : OBSERVATION + because + REASON (Theory)
