We try to provide an answer to theabove question by making a smartguess. For example, your guess couldbe :

µWhen the length of a simple pendulum is shortened, it will swingfaster.¶



Step 3 : Planning the experiment

What observation to make

What measurement to take

How to record the observations andmeasurements.



Step 4 : Controlling the variables

In sentences

In a table



Step 6 :Analysing and interpretingthe data.

Study your data

Try to see any pattern in your data. You may present in the form of a

graph



Step 7 : Making a conclusion

Make a conclusion whether the smartguess you have made is true



Step 8 : Making a report

Write a full report on yourinvestigation in your science report

book.
