Controlling VariablesTo test students understandings in what has to keep the same , what to change and what to observe while conducting or when carry out any fair test.

Students should well known with this three major elements in any investigation or experiments.

What to keep the same ?Any factors or elements that should be kept the same while conducting a fair test.Normally things that should be kept the same can be found whether in the diagram or in the statement.Students should well known through this item.

Figure 3 shows the apparatus used by Rohaya in an experiment. The bobs of the pendulums have the same mass. She used the same size and type of string.Types of stringSize of the stringMass of pendulums

What must be changed Any factors or elements show in the diagram or graph or table are changed or not the same while the fair test is carried out. The result of the experiment based on this matter.

What to change ?Size of the beakers

Table 1 shows the distance taken by a toy car after being pushed on different surfaces in 20 seconds.Types of the surface

SurfaceDistance /m Glass3Play wood2Bitumen0.5Carpet1

What to observe / whats your finding ?What to measure The result of any fair test or experiment is considered as what to observe / measure

Tips: Student must have the ability to determine this factor either in the table , diagram or in the statement.

Water temperature

Which model fall first

Model F is the most stable and model H is the less stable

Number of nails that can be supported

Making hypotheses / State the relationship between two factors. Normally student just make one statement by adding with what to change and what to observe. Sample answer: To investigate / find out the relationship between the number of teaspoon of salt and the time taken to dissolved.w.t.cw.t.o

Check your understandingThe size of the shadow was measured each time the object is moved nearer to the light source. To investigate the relationship between the distance of the object fromthe light source and the size of the shadow.What to changeDistance of the objectfrom the light sourceWhat to measureSize of the shadow

State the trend / pattern Students are advisable to study the pattern of data that has given in the question.

The answer normally in either one word , two words or three words. Sample answer Increasing Decreasing Remain , Same

Decreasing

Making conclusionMake one statement to conclude the finding of the fair test or investigation.

Sample answer: As the number of grasshopper increase / decrease the number of snake increase / decrease too.

Sometimes using a general statement also can be use as a conclusion. To use this statement students must be able to recognise the situation given.Sample statement. 1. Plants need sunlight to grow.2. Light travelled in straight line.3. Rusty is caused by the present of air and water.

Check you understanding.Light travel in a straight line.

Electric current produce heat

Aim / Purpose of the investigation Students are advisable to use the sample answers of making hypothesis.
