FOOD CHAIN  Boleh menggunakan padi tikus helang  Boleh menggunakan ayat Padi dimakan oleh tikus, tikus dimakan oleh helang.
Food chain 2 padi tikus helang 1. What happen to an eagle when the population of rat increase? Population of eagle increase. 2. What happen to paddy field when the population of eagle increase? Population of paddy field increase.
OBSERVATION  LIHAT  RASA  DENGAR  HIDU
OBSERVATI ON : Paku tekan jatuh apabila rod dipanaskan
State your observation after 10 minute the experiment are conducted. 1. The thermometer reading increase 2. The temperature reading in beaker X higher than temperature in beaker Y
SIMILARITIES  CARA MENJAWAB:  Both / Kedua-duanya  and / dan Contoh: ( Function of carbohydrate and fat ) 1.Both supply energy 2.Carbohydrate and fat supply energy
Similarities - example  Artery and vein 1.Both carries blood 2.Artery and vena carry blood
DIFFERENCES  CARA MENJAWAB:  …….but ………  ………. While ………
Artery and vein  Artery carry oxygenated blood but vein carry deoxygenated blood. • Artery carry oxygenated blood whereas vein carry deoxygenated blood.
X Y State the different in colour between car X and car Y. Nyatakan perbezaan antara kereta X dan kereta Y dari segi warna. X is white, Y is black or Car Y is darker than Car X
COMPARE  Similarities – 1 Mark  Differences – 1 Mark
Comparison between boiling and Evaporation – (Process) Similarities:- Boiling and evaporation (Both) are a process in which liquid changing into a gas and heat is absorbed. Differences:-  Evaporation takes place at all temperatures below boiling point but boiling takes place at the boiling point only.  Evaporation is a slow process, boiling is a very fast process  - Evaporation - takes place from the surface of the liquid. - Boiling – throughout the liquid.
EXPLAIN WHY…
CARA MENJAWAB..  USE WHAT AND WHY.. WHAT Renal artery has thicker wall because it carries blood in higher pressure. WHY
Knowing the limitation of measuring apparatus Measuring cylinder can 35 Measure the volume of liquid up to 0.1 ml accuracy. 34 34.2cm³ = or 34.2 ml
Burette 27 Burette can measure up to 0.1 ml accuracy 28 =27.8 cm³ or 27.8 ml
CALCULATION Step 1 – write down the formula  Load X distance of load = effort X distance of effort Step 2 – substitute with the relevant values  5 N X 16 cm = Effort X 20 cm Step 3 – solve the problem to get the answer  Effort = 5N X 16 cm 20 cm Effort = 10 N
WORK DONE  Work done =Force (N) X Distance (m)  Work done = (52+28)x10N X 10 m  = 800 N X 10 m  = 8000Nm  = 8000J  = 8 KJ 
VARIABLE  From table  From question  From picture / experiment  Graph
TABLE manipulated responding
Variables – from observation table Length of nichrome Current (A) wire (cm) 20 1.5 30 1.2 40 0.9
VARIABLE Manipulated : Length of nichrome wire Responding Ammeter : reading
From QUESTION manipulated  Both the iron and glass are heated simultaneously. The time taken for thumbtack drop is recorded. responding
Example:…… A student carried out an experiment to study the affect of light intensity on the rate of photosynthesis. Manipulated : Light intensity Responding : Rate of photosynthesis
From PICTURE / EXPERIMENT Responding Manipulated
Manipulated : Types of rod Responding : Time taken for thumbtack fall down
From graph Responding variable Manipulated variable
Current / A Manipulated : Thickness of wire Responding : ammeter reading Thickness of wire / mm

HYPOTHESIS  CARA MENJAWAB: 1. _____________ affects ____________________. Manipulated V Responding V
Hypothesis: Types of surface affects the thermometer reading
Position of centre of gravity affects the stability of object Hypothesis ???? Variables :- a.Constant – Base area b.Manipulated – Position of centre of gravity ( ) c.Responding – Stability of object
2. The lower / higher / increase / decrease ______ ** Gunakan manipulated V dahulu, diikuti dengan responding V ……
Hypothesis: Manipulated The conductivity of heat increase, time taken for thumbtack fall down decrease Responding
 The higher the centre of gravity (variable that is manipulated)  The less stable the object (variable that respond)
 The lower the centre of gravity (variable that is manipulated)  The more stable the object (variable that respond)
INFERENCE CARA MENJAWAB :  ________ _______ because ___________. What how ( responding v) why ( manipulated )
NECESSITY Food Oxygen Shelter  FISH …………………… DIE ………….……………  because NO ……….. …………………………………………………..
 Balloon slopes to the left because air has mass. Balloon B Balloon A
CONFIRMATION TEST _____________ tested by _______________ What? Substances use change from ____________ to _______________ . +ve result : EXAMPLE Carbon dioxide tested by lime water change to cloudy.
An acid tested by red litmus paper changed from red to blue. W HAT SUBSTANCE +VE USE RESULT Starch tested by iodine solution changed to dark blue
DEFINING OPERATIONALLY ___________ shows by _____________________ What what can you observed from t the experiment. @ ______________ is __________________________ What what can you observed from
Q: State the operational definition of a good heat conductor. Good heat conductor is the time taken thumbtack fall down /drop. OBSERVATION WHAT
Q: State the operational definition of a good heat absorber. Good heat absorber is the increasing the thermometer reading
