KEY WORD

OBSERVATIONState what you see in the picture, table, graph• What can you say• What can you observe

INFERENCE

Explain your observation.Give reason based on your observation.

Diagram shows a flowering plant in a pot. After 4 days the condition of the plant looks like as follow.

a) Write one observation after 4 days.

b) Based on the observation, give one reason.

The plant wilted

Because no water / sunlight

Number of elephant

2000 2001 2002 2003 2004 2005 Years

a) What can you observe?

b) What can you infer?

The number of elephant decreased

Because of illegal hunting.

River A

Bigger size fish

River B

Smaller size fish

Size of the fish in river A is bigger than river B

Because river A has no pollution compare to river B

OBSERVATION AND INFERENCE

OBSERVATION

INFERENCE

Because fish in river A got enough food than river B

CONTROLLING VARIABLES

The things you select in a fair test / experiment eg. What to change? What to measure? What keep the same?

Answer Key

Parameter object+Size of the ice-cubeAmount of waterPresence of sunlightType of plant

WHAT TO CHANGE? NUMBER OF BRICKS

WHAT TO OBSERVE? DISTANCE TRAVEL BY TOY CAR

WHAT KEEP THE SAME? SIZE OF BRICKS / SIZE OF PLANK /TYPE OF TOY CAR

PREDICTION

Using the data / from past experienceState what will happen next

Answer Key

Study the trend / pattern changes Predict the number eg 75oC / 10 g / 6cm

Predict the situation eg It will stay healthy It will be extinct

Based on the trend, predict the number of elephant for 2007

The elephant will extinct.

Predict the situation

INTERPRETING DATA

Write the aim / purpose of investigationState the trend of change in the dataState the relationship between the variablesState the conclusion for the experiment

Question KeyWhat is the aim / purpose of the investigation?Based on the ….. state the trend in the………What is the relationship between……………..What conclusion can be made from this investigation?

i. Aim / purposeTo find out the relationship between {what to change} and{ what to measure}

ii. Trend Increase : From small getting bigger or larger From lower became higher

Decrease: From bigger/larger getting smaller From higher getting lower

Did not change / unchanged

iii. RelationshipAs { what to change} increase / decrease, the{what to measure} increase/ decrease

iv. ConclusionAs { what to change} increase / decrease, the{what to measure} increase/ decrease

Science concept : Plant needs water to stay alive

General statement : Light can be reflected

As the WTC increase / decrease the WTM increase / decrease
