Scientific method is a systematic method used by scientists or researchers to solve problems related to science. This method involves several general steps to solve a problem using the correct methods
step 1 : Making observations
Using senses of sight, hearing, touch, taste or smell to gather information about an object or a phenomenon taking place.
Asking questions based on the inference made
Identifying the manipulated variable, responding variable and fixed variable(s) in an experiment to test the hypothesis that is formed.

step 6 : Controlling the variables
Making a general statement about the relationship between a manipulated variable and a responding variable to explain an event or observation. This statement can be tested to prove its validity
Identifying the manipulated variable, responding variable and fixed variable(s) in an experiment to test the hypothesis that is formed.
In an investigation, a variable is manipulated to observe its relationship with the responding variable. Simultaneously, other variables are fixed.
