The steps followed in an experiment include;
-Observation; this involves
taking note of something such as a curious phenomenon worth further thought and investigation
-Research; it involves forming a question so as to find out more about the natural phenomenon observed.
-Hypothesis, this is an informed guess as to the possible answer of the question.Its purpose is not to arrive at the perfect answer to the question but to provide a direction to further scientific investigation.
-Experiment, the hypothesis formed must be tested by conducting a well designed and controlled experiment. Its is an important step as it proves whether the hypothesis is correct or wrong.
-Analysis; it entails taking down the results and analyzing it together with the data and suing it to draw conclusion regarding the strength of the hypothesis.
-Conclusion; From the analysis a conclusion about the hypothesis can be drawn, explaining why the phenomenon occurs.
-Publish; the results may then be published as a reference and for future use and comparison.
