Physics (0625) IGCSE PAPER 62 .. EXPERIMENT QUESTION DOUBT

[Dubi Pro]

any one who can answer this experiment? breifly? Any Idea??

A student’s plastic bottle of water tips over in class.

Plan an experiment to investigate how the quantity of water in a plastic bottle affects its stability.

The plastic bottle holds up to 2000 cm3 of water and has a height of 42 cm.
(a) Write a plan for the experiment, including:
• the apparatus needed
• instructions for carrying out the experiment
• the values you will use for the quantity of water
• how you will make sure your results are as accurate as possible
• the graph you will plot from your results
A diagram is not required, but you may add to Fig. 4.1, or draw your own diagram, if it helps to
explain your plan.

Chill bro! If you're giving exams this May/June, then don't worry about it. 2014 syllabus doesn't include designing experiments. It's in 2016 syllabus, that's why you found it in the Specimen Paper!

Anyways, I've solved the question as follows:

A. Apparatus: Plastic bottle, measuring cylinder and large protractor.
B. Instructions:
-Filled in the bottle with fixed volume of water, measured using measuring cylinder
-Slightly push the bottle
-Measure the angle of tilt using a large protractor
C. Values: 400, 800, 1200, 1600 and 2000 cm^3
D. Accuracy: Measure angle a few times for same volume of water and take average
E. Graph: Plot graph of angle of tilt (y axis) against volume of water (x axis)
