How is observation used in the scientific method?
Observation consists of receiving knowledge of the outside world through our senses, or recording information using scientific tools and instruments. Any data recorded during an experiment can be called an observation. The Scientific Process
A scientific process or scientific method requires observations of nature and formulating and testing the hypothesis. It consists of following four steps.
Observe something and ask questions about a natural phenomenon (scientific observation)
Make your hypothesis
Make predictions about logical consequences of the hypothesis
Test your predictions by controlled experiment, a natural experiment, an observational study or a field experiment
Create your conclusion on the basis of data or information gathered in your experiment.
