Scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
The scientific method includes four main steps:
The scientific method is the most reliable technique for obtaining new knowledge because it is purely based on measurable evidence.
Scientific articles based on scientific method are, as a rule, most clear because they are focused on verification of one or several hypotheses. The scientific method helps to prepare and run well-structured and clear experiments. Best scientific journals often require all submitted articles to be written using the scientific method.
To make it more clear, this sample experiment contained three variables:
independent - reaction temperature;
dependent - yield of the reaction
controlled - concentrations of reagents, time of reaction, pressure, volumes, light, stirring and any other parameters, which may affect the yield of the reaction.
