Use our 5 senses eg eyes, nose, ear, skin and mouth.Identify all the information given.Do not give reason

.

eg

The number of elephant decrease

Plant B is bigger than plant A

State one inference…

Give reason for youranswer in ….

Explanation from an observation why it happen - give reasons. a) observation + why

Think why it happens – using our mind.

Animals extinct because of …………………… not enough food illegal hunting The plant getting withered because …. a) didn’t get enough.. b) didn’t get any… c) didn’t get the right amount of… d) there is no..

State two variables in

the Investigation

In the investigationstate i what to change ii what to measure iii what to keep the same

State two information gathered …………..

Identify the variables.

What to change (manipulated)Look for the things difference /changes in the diagram The weight of load hangedWhat to measure (responding)Look for the result The length of the springWhat to keep the same (control)Look for the things that are the same in the diagram The size of the spring

State a hypothesis for thisinvestigation

Using the information above, write a hypothesis

Hypothesis can be made based on the inference.

Look for what to change and what to measure

Relates between what to change and what to measure

The heavier the load the longer the spring.

The bigger / the smallerThe longer / the shorterThe thicker / the thinnerThe more / the least

As the {weight of the load } increase, the {length of the spring } also increase

As the number of pupil increase the classroom temperature also increase

What can you conclude from this activity/fair test.

State your conclusion based on the activity/fair test.

What the result means?

What have you learnt from this activity?

The results/findings from an activity/ fair testIt relates between what is changed and what is measured.

Use Science Concept

When / If /As {what to change] increase / decrease, the { what to measure} increase / decrease.eg

As the time to heat the water increase, the water temperature also increase

From the fair test, we found out that………

plant needs sunlight to stay alive

animals need food to stay alive
