Question 1: {Planning - 15 marks}
● This question tests your ability to plan experiments.
● While solving this question, keep these points in mind:
○ Defining the problem {3 marks}
○ Method of data collection {4 marks}
○ Setup for the apparatus {1 mark}
○ Method of Analysis {2 marks}
○ Safety considerations {1 mark}
○ Any additional details {4 marks}
1. Defining the problem:
➔ Firstly, identify the variables in the experiment:
◆ Independent variable: variable that you will vary in the
experiment.
◆ Dependent variable: variable that you will measure as a result
of change in independent variable
➔ After the identification of variables, you are required to identify the
quantities you are going to keep constant. Any quantity which may vary
your results, other than quantities involved in the experiment, must be
kept constant. Mention ‘how’ you are going to make sure it does not
change, and ‘why’ you think it should be kept constant. While you do this,
keep in mind one thing that there may be a lot of such quantities that need
to be kept constant; always mention that quantity which DIRECTLY
affects the variables being measured.
2. Methods of data collection:
➔ Now that you have mentioned the variables, you need to describe how to
measure them. Describe the method to vary the independent variable, and
a method to measure
